DJI Agras T100 Tutorials: How to Edit Fields in Route Mode (FAA Part 137 & FAA Part 107)

🇺🇸 U.S.A. FIRST — DJI Agras T100 Field Editing, Route Optimization & Agricultural UAS Compliance

A field plan is not finished simply because a boundary appears on the remote controller. The quality of that boundary—and the routes generated inside it—directly affects how efficiently the DJI Agras T100 turns, how consistently it covers the crop, how far it remains from obstacles, where it begins the operation, and whether spray is applied only where intended.

Fields also change. An original map may include an inaccurate corner, an obstacle that was drawn too small, a non-application area that needs revision, or one large irregular block that would be easier to operate as several smaller fields. A grower may want full interior coverage one day and boundary-only spraying another. The operator may need to reserve a larger margin along one road without changing the opposite side of the field, or complete only a selected proportion of the route before weather or available material changes.

The DJI Agras T100 Field Editing workflow in Route Mode gives operators the tools to correct and reorganize that plan before flight. You can rename or delete a field, divide one field into multiple fields, preserve the original with Save As, fine-tune individual boundary points, revise obstacles and non-application areas, change route spacing, set overall and one-side margins, adjust obstacle clearance, relocate the start point, configure boundary spraying, control route direction, and segment the route for a partial-field operation.

This Ares Acres tutorial expands DJI’s field-editing demonstration into a complete operating guide. It explains not only which controls to select, but why the order of those changes matters and what should be verified before the T100 is allowed to use the edited field.

Ares Acres supports DJI Agras operators with agricultural aircraft, OEM replacement parts, diagnostics, technical education, and field-operation resources.

Quick Answer: How Do You Edit a Field in DJI Agras T100 Route Mode?

Operation Mode Switch → Route → Field List → Select Field → Rename, Delete, Divide, or Edit → Use Field Division if separate field records are needed → Add cutting lines with boundary points or crosshair anchor points → Use Save As to preserve the original → Select the field again → Field Editing icon → Choose Field, Obstacle, or Non-Application Area → Fine-tune boundary points → Set route spacing → Set the overall field margin → Set one-side margins afterward → Set obstacle safety distance from 1.5–5 m → Choose the start point → Configure boundary spraying and direction → Review sided spraying → Adjust route direction or Auto Optimization → Segment the route if only part of the field will be operated → Save → Name Field → Save Again → Use.

The most important editing principle is order of operations. Establish accurate geometry first. Then set route spacing and the overall margin. Apply one-side margin adjustments only after the overall margin is finalized. After that, verify obstacles, start point, boundary behavior, route direction, route segmentation, and the complete generated task.

Why a Well-Edited Field Improves Operation Efficiency

The route planner builds the flight from the information stored in the field. If the field geometry is inaccurate, the generated route may be inefficient even when the aircraft follows it perfectly.

A well-edited field can help reduce:

  • unnecessary turns;
  • duplicated passes;
  • untreated strips;
  • excessive overlap;
  • route lines outside the crop;
  • passes too close to roads, trees, poles, or buildings;
  • incorrect start-point transitions;
  • repeated setup for an overly large or complex field;
  • application over non-target areas; and
  • confusion between operators using the same field library.

Editing is especially valuable when a field was originally created from satellite imagery, a quick crosshair plan, an older survey, or approximate boundary points. The final task should reflect current field conditions rather than the map that happened to be available when the record was first created.

Field Editing vs. Field Division vs. Route Segmentation

These three tools solve different problems and should not be treated as interchangeable.

Function What it changes Best use What it does not do
Field Editing Changes the stored field geometry or its route-related settings. Correcting boundaries, obstacles, margins, start point, direction, or route behavior. It does not necessarily create separate field records.
Field Division Splits one large or complex field into several fields using cutting lines. Operating different sections separately or simplifying a complex field. It is not merely a temporary partial-route selection.
Save As Preserves the original field while saving the fields created from the division workflow. Keeping a recoverable original and separate divided versions. It does not guarantee that every resulting field is operationally ready without review.
Route Segmentation Selects a desired proportion of the generated route for the current operation. Operating only part of a field without necessarily creating new field records. It does not redraw the original boundary or replace field division.
Non-Application Area Editing Revises a region inside or near the field where material should not be applied. Protecting waterways, structures, sensitive crops, buffers, or other excluded zones. It does not replace accurate obstacles or field boundaries.

A Simple Decision Rule

  • If the stored boundary is wrong, edit the field.
  • If one large field should become several reusable fields, divide it.
  • If the field is correct but today’s operation should cover only part of its route, use route segmentation.
  • If the original may still be useful, use Save As during division.

Before Editing: Inspect the Field and Protect the Original

Before changing a saved field, compare the digital map with the current operation site. Identify:

  • the actual crop boundary;
  • recent field expansion or contraction;
  • roads, ditches, waterways, and windbreaks;
  • poles, wires, buildings, irrigation equipment, and tree lines;
  • sensitive neighboring crops;
  • non-application zones and required buffers;
  • terrain changes;
  • logical places to divide the field;
  • safe takeoff and landing locations;
  • practical refill and battery-change positions; and
  • the expected Return-to-Home route.

If the field is valuable, frequently reused, or difficult to recreate, preserve a recoverable version before making substantial geometry changes. The DJI tutorial specifically demonstrates Save As during field division when the operator wants to keep the original field as well as the resulting divided fields.

Before operating the edited task, complete the aircraft checks in the DJI Agras T100/T50 Pre-Flight Safety Tutorial.

U.S. Regulatory Context: FAA Part 107, Part 137 & the T100

Field editing is an aircraft-interface workflow. It does not, by itself, grant regulatory authority to conduct an agricultural drone operation in the United States.

FAA Part 107

14 CFR Part 107 is the FAA’s Small Unmanned Aircraft Systems rule and generally applies to aircraft weighing less than 55 pounds at takeoff. A Part 107 Remote Pilot Certificate is also the pilot credential used in the FAA’s current civil UAS agricultural-operations framework, including under applicable exemptions and authorizations.

The DJI Agras T100 is a large agricultural aircraft when operated at weights at or above 55 pounds. It therefore should not be described as operating under Part 107 alone. The governing approval structure depends on aircraft weight, mission, exemption, certificate, operating limitations, and other facts.

FAA Part 137

14 CFR Part 137 governs agricultural aircraft operations involving the dispensing of certain materials and related agricultural operations. The FAA states that operators conducting covered agricultural operations must hold an Agricultural Aircraft Operator Certificate, commonly called an AAOC, unless specifically relieved from that requirement.

For UAS agricultural operations, the FAA process can also require an exemption from regulations written for crewed aircraft. For aircraft weighing 55 pounds or more, the operating framework can involve a Section 44807 exemption, Part 91 conditions, and a Certificate of Waiver or Authorization, as applicable.

What This Means for Field Editing

An operator should verify that the edited route remains consistent with:

  • the operator’s AAOC;
  • the applicable exemption and its conditions and limitations;
  • aircraft registration and identification requirements;
  • the authorized aircraft and operating weight;
  • the pilot qualification requirements;
  • airspace authorization or COA requirements;
  • visual-line-of-sight and operating-area restrictions;
  • product labels and state pesticide rules;
  • local environmental and property restrictions; and
  • recordkeeping requirements.

Do not use the “FAA Part 107 & FAA Part 137” language in this title to imply that selecting Route Mode makes an operation compliant. The edited mission must be flown under the authority actually applicable to the aircraft and operation. This article is operational education, not legal advice.

Step 1 — Switch the Operation Mode to Route

From the operation-mode switch interface, select Route.

Route Mode is the planned-field environment in which the controller uses a saved boundary to generate and execute an organized set of operation lines. If you are new to this workflow, review the DJI Agras T100 Route Mode Field Planning & Task Execution Tutorial.

Before editing, confirm that the controller is displaying the correct account, team, aircraft, region, and field library. Similar field names or neighboring polygons can make it easy to select the wrong record.

Step 2 — Open the Field List

Click the Field List on the left side of the interface.

The field list is the starting point for selecting an existing field. Use the map position, field name, geometry, and any other available identifiers to confirm the correct record.

If several fields have generic names, renaming them with a consistent convention can reduce future errors. A useful field name may include the farm, block, crop, season, or section, provided it remains concise enough to recognize on the controller.

Step 3 — Select the Field You Want to Edit

Choose the field that requires modification.

Before changing anything, inspect its displayed shape. Ask:

  • Does it match the intended farm and crop block?
  • Is the boundary current?
  • Are the obstacles and excluded regions visible?
  • Is this the original field or an already divided copy?
  • Will another operator need the unmodified version later?

This verification is especially important before using Rename, Delete, division, or Save As.

Step 4 — Rename the Field When Needed

Use the Rename option when the current field name is unclear, duplicated, outdated, or inconsistent with the operation’s naming system.

Good naming reduces selection mistakes. For example, a team might use a structure such as:

Farm – Block – Crop – Year – Section

The exact convention matters less than consistency. Avoid naming every field “Field 1,” “New Field,” or another label that becomes ambiguous when several records are displayed together.

After renaming, verify that the field geometry—not only the label—still matches the intended location.

Step 5 — Delete a Field Only After Verifying the Record

The field list also provides a Delete option.

Deletion should be reserved for an obsolete, duplicate, test, or incorrect field that is no longer needed. Before deleting:

  1. Confirm the field name and map position.
  2. Determine whether the field is referenced by current or historical operations.
  3. Confirm whether an original or alternate version exists.
  4. Make sure another team member does not still need it.
  5. Avoid deleting a field merely because its boundary needs correction; editing may be more appropriate.

Field deletion is different from removing a single boundary point. One removes the saved field record; the other changes its geometry.

Step 6 — Decide Whether Field Division Is Appropriate

If a field is large or complex in shape, the tutorial recommends using Field Division to create several fields that can be operated separately.

Field division can be useful when:

  • one field contains narrow necks or separated lobes;
  • terrain or obstacles make one continuous mission inefficient;
  • different sections require different products, rates, or timing;
  • the operator wants separate refill or battery-management plans;
  • weather conditions may allow only one section to be completed;
  • access points favor independent sections; or
  • one generated route would create excessive non-productive transitions.

Do not divide solely to make the map look cleaner. Every new field becomes another record to name, verify, configure, and manage.

Step 7 — Open Field Division

Click the Field Division button.

The division workflow creates cutting lines through the original geometry. The goal is to place a line that separates the field into useful operational sections without producing tiny slivers, impractical turns, or new shapes that are harder to operate than the original.

Before drawing the cut, identify where real field conditions already suggest a division:

  • a road or lane;
  • a ditch or waterway;
  • a windbreak;
  • a natural crop boundary;
  • a terrain change;
  • a change in product or rate;
  • a narrow connection between larger areas; or
  • an operational break that supports refill or battery logistics.

Step 8 — Add a Cutting Line With Boundary Points

Click boundary points to create the cutting line.

The line should intersect the field geometry in a way that produces valid, usable sections. After adding it, inspect both resulting shapes.

Cutting-Line Check

  • Does the line divide the intended sections?
  • Does either new field contain a very narrow or unusable strip?
  • Does the cut pass through an obstacle or non-application area in a confusing way?
  • Will each resulting section generate sensible flight routes?
  • Can each field be reached and operated safely?
  • Do both fields still reflect the real crop boundary?

If the division is not useful, revise the cut before saving rather than accepting poor geometry.

Step 9 — Use Save As to Preserve the Original Field

If you want to retain the original field, click the field and choose Save As.

The DJI tutorial explains that this preserves:

  • the original field; and
  • the fields divided from the original.

This is valuable when the undivided record may still be needed for reference, later planning, a different application method, or recovery from an editing mistake.

Name the divided fields clearly so the operator can distinguish them from the original. Terms such as North, South, East, West, Upper, Lower, or Section A/B may work when they correspond to obvious real-world geometry.

Step 10 — Add Anchor Points Outside the Field With the Crosshair

The field can also be divided by moving the crosshair to create anchor points outside the field and using the line between those points as the cut.

This approach can be helpful when the desired division does not begin and end cleanly on existing boundary points. Place the external anchor points so the connecting line crosses the field exactly where the division should occur.

Verify that:

  • both anchors are outside the correct sides of the field;
  • the connecting line crosses the entire intended section;
  • the line does not create an accidental extra fragment;
  • the new polygons remain closed and valid; and
  • the resulting fields match the operational plan.

The anchor points are planning controls for the dividing line. They should not be confused with new crop-boundary points that expand the actual field.

Step 11 — Reopen the Field for Editing

In the field list on the left, select the field you want to modify and click the Field Editing icon in the lower-right corner.

This returns the selected record to the editing interface. Reconfirm the field name and location, especially if division created several similar shapes.

For controller-interface orientation, see the DJI Agras T100/T50 Remote Operation View Tutorial.

Step 12 — Choose What You Want to Edit

The editing interface can be used to select different areas or elements of the field, including:

  • the field boundary;
  • obstacles; and
  • non-application areas.

The source tutorial focuses primarily on field-boundary editing, but the operator should still inspect all three layers. A corrected boundary can change the relationship between the route and an obstacle or excluded region.

Field Boundary

Defines the outer operating geometry from which the route is generated.

Obstacle

Represents a hazard or protected feature inside or near the field.

Non-Application Area

Represents a region where the aircraft should not apply spray or spread material, even if that region lies inside the broader field geometry.

These layers should complement one another. A non-application area should not be used to hide a badly drawn outer boundary, and an obstacle boundary should not be used as a substitute for an agronomic or label-required exclusion zone.

Step 13 — Select an Inaccurate Boundary Point

If a boundary point is inaccurate, select it in the Boundary Tuning panel.

Zoom in enough to compare the point with the high-definition map or verified field edge. Keep enough surrounding context visible to understand how the selected point connects to its neighbors.

Common boundary-point errors include:

  • a corner placed inside the crop;
  • a point placed outside the property or treatment area;
  • a line crossing a road or ditch;
  • a point offset by old or inaccurate imagery;
  • an overly simplified curve; or
  • a point that creates an unnecessary spike in the polygon.

Step 14 — Fine-Tune the Point With the Arrow Keys

Use the arrow keys in the left-side Boundary Tuning panel to move the selected boundary point.

Fine-tuning is useful when the field is fundamentally correct but one point needs a small positional adjustment. Move the point gradually and observe both connected boundary lines.

A point has two relationships:

  • the line entering it from the previous point; and
  • the line leaving it toward the next point.

Moving the point can correct one side while making the other less accurate. Review the complete corner, not only the point itself.

Step 15 — Use Previous and Next to Inspect Adjacent Points

Click Previous or Next to jump quickly between adjacent boundary points.

This is useful for auditing a long or irregular boundary systematically. Start at one recognizable corner and move point by point around the field so no section is skipped.

While reviewing adjacent points, look for:

  • inconsistent spacing;
  • sudden spikes or inward cuts;
  • boundary lines crossing non-target areas;
  • sections that should follow a road, tree line, or crop edge more closely; and
  • places where an additional point may be required to represent the shape accurately.

Step 16 — Reset the Current Boundary Point if Needed

Click Reset to cancel adjustments previously made to the currently selected boundary point.

Reset is useful when fine-tuning made the geometry worse or when the original position was more accurate than the new one.

The tutorial describes Reset in relation to the current boundary point. Do not assume it reverses every edit made across the whole field. Verify what changed on screen before continuing.

Step 17 — Delete an Unnecessary Boundary Point

Click Delete to remove the selected boundary point. The tutorial also demonstrates that a boundary point can be removed by double-clicking it.

Delete a point when it:

  • creates an artificial spike;
  • duplicates another nearby point;
  • was added accidentally;
  • causes an incorrect bend; or
  • adds complexity without improving boundary accuracy.

After deletion, the neighboring points will be connected differently. Inspect the replacement line to make sure it does not cut through the crop, road, obstacle, waterway, or another excluded region.

Step 18 — Click a Blank Area to Save the Point Adjustment and Exit

When the current boundary-point adjustment is correct, click a blank area of the interface to save that adjustment and exit the point-editing state.

After exiting, zoom out and review the complete field. A local change that looks correct at close range may alter the larger route geometry in an unexpected way.

Step 19 — Open Flight Route Settings

Use the left-side Flight Route Settings panel to configure the generated operation route.

This panel includes route spacing and field-margin controls. These values are related, but they serve different purposes:

Setting What it controls Main risk if incorrect
Route Spacing Distance between neighboring operation passes. Gaps when too wide; overlap or inefficiency when too narrow.
Field Margin Offset between flight routes and selected field boundaries. Route too close to or too far from the field edge.
Obstacle-Boundary Safety Distance Distance between the route and a mapped obstacle boundary. Insufficient obstacle separation or unnecessary loss of usable route area.

Do not choose route spacing solely from a prior job. Effective width changes with payload configuration, material, altitude, speed, droplet or particle behavior, wind, crop canopy, and other field conditions.

Step 20 — Adjust Route Spacing

Set the route spacing appropriate for the intended application.

Route spacing should be based on verified effective coverage, not only the nominal capability of the aircraft. Before finalizing it, consider:

  • nozzle or feeder configuration;
  • spray or spread material;
  • planned flight altitude;
  • planned operating speed;
  • droplet size or particle characteristics;
  • wind speed and direction;
  • crop height and canopy;
  • terrain;
  • desired overlap; and
  • label or agronomic requirements.

If route spacing is too wide, untreated strips may remain between passes. If it is too narrow, overlap can increase material use, flight time, refill demand, crop exposure, and cost.

For spreading-specific setup, review The DJI T100 Spreading System Tutorial.

Step 21 — Set the Overall Field Margin First

Under Widen Field Margins, select Overall when one unified margin should be reserved for all flight routes around the field.

The overall setting establishes the baseline relationship between the generated route and the complete field perimeter.

Before accepting it, inspect:

  • roads or occupied areas along the field edge;
  • neighboring properties or crops;
  • trees and windbreaks;
  • fences, poles, and wires;
  • waterways and drainage features;
  • field-edge slope or terrain changes;
  • label-required setbacks; and
  • whether boundary spraying will be enabled later.

The most important sequencing instruction in the source tutorial is: set the overall margin before adjusting a one-side margin.

Step 22 — Apply a One-Side Margin After the Overall Margin

Select One Side when only a particular field boundary—or a selected range of boundaries—needs a different route margin.

Click the relevant field boundary or select the required boundary range, then adjust the margin for the flight routes near those selected edges. The margins for the remaining routes stay unchanged.

This can be useful when:

  • one edge borders a public road;
  • one side is next to a sensitive crop;
  • a waterway follows only part of the perimeter;
  • one boundary contains trees or power infrastructure;
  • the downwind side needs a different operational plan; or
  • one field edge has a larger legal, label, or property setback.

Why the Order Matters

The tutorial warns that changing the overall margin after a one-side adjustment can affect the one-side margin. Use this sequence:

  1. Finalize the overall margin.
  2. Select One Side.
  3. Choose the specific boundary or boundary range.
  4. Enter the special margin.
  5. Verify the selected side and the unchanged sides.
  6. Click OK to complete the settings.

If the overall margin must be changed later, recheck every one-side adjustment before saving.

Step 23 — Set the Obstacle-Boundary Safety Distance

Obstacle-boundary safety distance is the distance between the generated flight route and the mapped obstacle boundary.

In the demonstrated T100 workflow, this value can be set from 1.5 meters to 5 meters based on the actual situation.

Do not interpret that software range as a universal guarantee that every obstacle can be safely approached within those distances. Appropriate separation also depends on:

  • obstacle size, height, and shape;
  • branches, cables, arms, or wires extending beyond the mapped boundary;
  • map alignment and point accuracy;
  • GNSS or RTK performance;
  • wind and aircraft movement;
  • route speed and turn geometry;
  • payload and aircraft state;
  • terrain and crop height;
  • people, vehicles, or animals nearby; and
  • the operator’s exemption, manual, label, or site requirements.

If the real operation requires more clearance than the interface can represent through this setting, redesign the boundary, obstacle geometry, field margin, or operation instead of assuming the maximum displayed value solves the hazard.

Step 24 — Review or Change the Start Point

By default, the start point is set to the waypoint closest to the agricultural drone.

To change it, click Start Point and select a new start point.

The nearest point is not always the best operational point. Consider:

  • the takeoff location;
  • refill and battery-change logistics;
  • wind direction;
  • terrain and obstacles;
  • the safest entry path;
  • where the aircraft should finish;
  • whether the first pass begins near a sensitive boundary; and
  • the Return-to-Home path.

If the aircraft is moved after the route is planned, verify the start point again. A point that was previously nearest may no longer produce the most sensible transition.

Step 25 — Open Advanced Settings for Boundary Operations

In Advanced Settings, choose whether the aircraft should fly and apply along the field boundary.

Boundary operation can improve edge coverage when the crop and application plan require it, but it can also increase overlap or bring the aircraft closer to boundary hazards. Review the perimeter carefully before enabling it.

The demonstrated options include Route and Boundary and Boundary Only.

Step 26 — Understand Route and Boundary

When Route and Boundary is selected, the aircraft first completes the routes through the middle of the field and then flies and applies along the field boundary.

This can improve spraying effects at the perimeter when the interior passes alone would leave insufficient edge coverage.

Before using Route and Boundary, check:

  • whether the boundary is mapped accurately;
  • whether the field margin supports the desired edge pass;
  • whether obstacles or wires exist near the perimeter;
  • whether interior routes already create sufficient edge overlap;
  • whether the product label allows the planned boundary treatment;
  • whether neighboring crops or properties could be affected; and
  • whether the aircraft can complete the boundary turn safely.

Step 27 — Understand Boundary Only

When Boundary Only is selected, the aircraft applies only along the field boundary rather than completing the interior route set.

Boundary Only can be useful for perimeter-focused applications, but it should not be mistaken for full-field coverage.

Verify:

  • the boundary treatment is the actual objective;
  • interior crop areas do not require application;
  • the planned width remains inside the permitted treatment zone;
  • the boundary route does not create excessive overlap at corners; and
  • the material quantity estimate reflects a perimeter-only job.

Step 28 — Select Clockwise or Counterclockwise Boundary Direction

Choose whether the aircraft follows the boundary clockwise or counterclockwise.

The direction can affect:

  • which side of the aircraft faces the field;
  • the relationship between active sprinklers and the crop;
  • the sequence of corners;
  • the first and final boundary segment;
  • wind exposure;
  • operator visibility; and
  • how the aircraft approaches nearby obstacles.

Select the direction that produces the clearest and safest boundary sequence for the real site. Trace the complete perimeter after choosing it.

Step 29 — Evaluate Sided Spraying Carefully

The tutorial explains that when Sided Spraying is enabled, the aircraft uses selected sprinklers depending on the maneuver:

  • during lateral movement, only the outer sprinklers operate; and
  • during bypassing, only the inner sprinklers operate.

The precise sprinkler behavior can depend on the installed configuration, software, firmware, and route state, so confirm the current controller display and DJI documentation.

Sided spraying is intended to direct application toward the target side while limiting treatment outside the desired area. It is not automatically appropriate for every crop, chemical, boundary, or obstacle-bypass maneuver.

Sided Spraying, Overspray & Phytotoxicity Risk

DJI’s tutorial specifically warns that enabling sided spraying during bypassing can create an overspraying risk. It recommends not enabling this function when spraying crops prone to phytotoxicity.

Phytotoxicity can result when a crop receives excessive concentration, repeated coverage, an incompatible product, or treatment under unsuitable environmental conditions. Route geometry is only one factor; the operator must also consider:

  • product label directions;
  • crop sensitivity;
  • application rate;
  • overlap from interior and boundary passes;
  • nozzle output;
  • speed changes during turns or bypassing;
  • wind and downwash;
  • tank mixture; and
  • prior applications.

If there is uncertainty, use a more conservative route plan and consult the product label, agronomist, applicator guidance, and applicable requirements. Software convenience should not override crop-safety limits.

Step 30 — Open Route-Direction Adjustment

To change flight-route direction, either:

  • click Settings to enter the route-direction fine-tuning interface; or
  • click the Course Angle icon directly.

Route direction affects the number of passes, turn count, pass length, wind relationship, slope relationship, obstacle interaction, and travel efficiency. The shortest-looking angle is not always the safest or most effective.

Step 31 — Disable Auto Optimization Before Manual Direction Changes

Disable Auto Optimization before manually adjusting route direction.

If Auto Optimization remains active, the system may continue selecting or modifying the route direction instead of preserving the manual angle you are trying to establish.

Before changing direction, note the existing route and compare:

  • number of passes;
  • number and location of turns;
  • route length;
  • short or fragmented lines;
  • obstacle bypasses;
  • start-point transition; and
  • field-edge coverage.

Step 32 — Align the Route With a Selected Field Boundary

Double-click a selected field boundary to align the route direction quickly with that boundary.

This is useful when crop rows, planting direction, drainage, or the field’s longest edge follows a clear boundary line.

Alignment should still be verified against:

  • actual crop-row direction;
  • terrain and slope;
  • prevailing wind;
  • field width;
  • obstacle placement;
  • turn space; and
  • the desired start point.

The visually longest boundary is not always the best route heading.

Step 33 — Drag the Route-Direction Icon

Drag the route-direction icon to rotate the planned flight lines.

Use this for larger directional changes. Watch how the entire route regenerates as the angle moves. A small angle change can alter the number of passes, create short edge fragments, or move turns toward a hazard.

Compare at least two or three plausible orientations when the field is irregular. Choose the direction that balances coverage, safety, turn geometry, wind, and operational efficiency.

Step 34 — Use Fine-Tuning Controls for Minor Changes

If only a small route-angle correction is needed, use the left-side fine-tuning icons.

Fine adjustments can help align the path with crop rows or remove inefficient short passes without dramatically rotating the mission.

After every adjustment, review the start, finish, turns, obstacle relationships, and field-edge coverage. Do not evaluate the center lines alone.

Step 35 — Reconsider Auto Optimization

DJI advises enabling Auto Optimization so the system can automatically select an optimal flight-route direction.

Auto Optimization can be a strong starting point or comparison, but “optimal” is based on the system’s route-planning logic and available map information. The operator must still account for conditions the app may not fully understand, such as:

  • current wind;
  • wet or soft access areas;
  • temporary equipment;
  • field crew position;
  • product restrictions;
  • operational staging; and
  • a preferred refill or battery-change sequence.

If you compare manual and automatic directions, use the route that makes the complete mission safer and more practical. Click Yes to complete the route-direction adjustment.

Step 36 — Use Route Segmentation for a Partial-Field Operation

If the operation does not need to cover the entire field, select Route Segmentation.

Drag the slider to select the desired proportion of the flight route, then click OK.

Route segmentation can be useful when:

  • only part of the field requires treatment;
  • limited material is available;
  • weather provides a short operating window;
  • a customer wants one section completed first;
  • part of the field is not ready;
  • the operation will be completed across separate shifts; or
  • the operator wants to test settings on a controlled portion.

Route Segmentation Is Not Field Division

Route segmentation controls how much of the generated route is selected for operation. Field division creates separate reusable field geometries. If the sections need different permanent boundaries, names, obstacles, margins, rates, or recurring schedules, field division may be the better tool.

After moving the segmentation slider, verify exactly which route lines remain active. A desired proportion does not automatically mean the selected portion corresponds to the most important agronomic area.

Step 37 — Save the Edited Field

Click Save after completing the geometry and route settings.

Before saving, perform a final review:

  • field boundary;
  • divided-field geometry, if applicable;
  • obstacle locations;
  • non-application areas;
  • route spacing;
  • overall field margin;
  • every one-side margin;
  • obstacle safety distance;
  • start point;
  • boundary-operation setting;
  • clockwise or counterclockwise direction;
  • sided-spraying selection;
  • route angle;
  • Auto Optimization state; and
  • route segmentation.

Step 38 — Enter the Field Name and Save Again

Enter the field name and click Save again to complete field editing.

Use a name that distinguishes the edited field from the original and from any divided sections. If Save As was used, confirm that all intended records appear in the field list with clear names.

Step 39 — Click Use to Operate Over the Field

Click Use to prepare the selected field for operation.

Do not treat Use as immediate authorization to launch. First review the generated task in the current aircraft state and operating environment.

Confirm:

  • the correct field was selected;
  • all routes render as expected;
  • the start and entry paths are safe;
  • application parameters match the product and crop;
  • the aircraft and payload are correctly configured;
  • batteries and power-system equipment are ready;
  • positioning and controller link are acceptable;
  • weather and airspace are suitable; and
  • the operation remains within the operator’s FAA and local authority.

How to Review the Edited Route Before Launch

Boundary Geometry

  • Does the outer boundary match the current crop and property limits?
  • Were inaccurate points corrected without creating new errors?
  • Are divided fields closed, usable, and clearly named?
  • Does any boundary line cross a road, ditch, building, or non-target crop?

Route Geometry

  • Does spacing match verified effective coverage?
  • Are route lines efficient and free of unnecessary fragments?
  • Does the selected angle follow the intended crop or terrain direction?
  • Are turns clear of obstacles and boundaries?
  • Is the segmented portion the correct part of the field?

Margins and Obstacles

  • Was the overall margin set before one-side margins?
  • Are all one-side changes still present after later edits?
  • Is the 1.5–5 m obstacle-distance setting appropriate within the larger safety plan?
  • Do mapped obstacle boundaries include the full physical hazard?

Application Behavior

  • Is the operation Interior, Route and Boundary, or Boundary Only as intended?
  • Is clockwise or counterclockwise direction correct?
  • Is sided spraying appropriate for the crop and maneuver?
  • Could boundary or bypass spraying create overlap or phytotoxicity risk?
  • Do rate, speed, nozzle, droplet, feeder, or material settings match the job?

Operational and Regulatory Readiness

  • Is the operator using the authority applicable to the aircraft and mission?
  • Are AAOC, exemption, pilot, aircraft, COA, and airspace conditions satisfied as applicable?
  • Are product-label and state requirements satisfied?
  • Are the takeoff, landing, refill, and Return-to-Home areas clear?
  • Can the pilot supervise and pause the mission if field conditions differ from the plan?

Decision Table: Which Editing Tool Should You Use?

Field-planning problem Recommended tool Reason
One corner is mapped inaccurately Boundary Tuning Corrects the individual point without rebuilding the field.
Field name is unclear Rename Reduces selection errors without changing geometry.
Duplicate test field is no longer needed Delete after verification Removes an unnecessary record.
Large irregular field should be operated in separate reusable sections Field Division Creates separate field geometries.
Original field must remain available Save As during division Preserves the original and divided fields.
Desired cutting line does not match existing boundary points External crosshair anchor points Allows a line to cross the field from outside anchors.
Entire perimeter needs a larger route offset Overall Margin Applies a common baseline margin.
Only the road-side edge needs more separation One-Side Margin after Overall Changes selected boundary routes while leaving the rest unchanged.
Route is too close to a mapped obstacle Obstacle-Boundary Safety Distance and geometry review Adjusts separation within the supported 1.5–5 m setting range.
Aircraft should begin from a different side Start Point Changes the route entry location.
Interior and perimeter both require treatment Route and Boundary Adds a field-edge application after interior routes.
Only the perimeter requires treatment Boundary Only Restricts the application plan to the boundary route.
Flight lines do not match crop-row direction Route Direction controls Allows manual alignment or automatic optimization.
Only part of today’s route should be operated Route Segmentation Selects a portion without necessarily creating new field records.

Overall Margin vs. One-Side Margin: Exact Order

Sequence Action Verification
1 Open Flight Route Settings Correct field and route are displayed.
2 Select Overall Baseline margin applies around the complete field.
3 Enter and verify the overall value Route remains appropriate on all sides.
4 Select One Side Special boundary editing becomes active.
5 Click one boundary or select a range Only the intended edge is highlighted.
6 Enter the special margin Nearby routes move as intended; other routes stay unchanged.
7 Click OK Setting is accepted.
8 Recheck after any later overall change One-side margins may have been affected.

Boundary Spraying Decision Table

Setting Aircraft behavior Best-fit use Main caution
Interior route only Operates the generated middle-field routes without an added boundary pass. Full-field treatment where existing edge coverage is sufficient. May leave inadequate perimeter coverage if spacing and margins are not planned correctly.
Route and Boundary Completes interior routes, then operates along the field boundary. Jobs needing improved edge coverage. Can create overlap or bring application closer to neighboring areas and hazards.
Boundary Only Operates only around the field boundary. Perimeter-specific treatment. Does not provide full interior coverage.
Sided Spraying Uses selected inner or outer sprinklers during demonstrated maneuvers. Directing treatment toward the intended side when configuration and crop allow. Bypassing can create overspray; avoid when phytotoxicity risk makes repeated application unacceptable.

Common Field-Editing Mistakes

1. Editing the Wrong Field

Similar names and nearby polygons can look alike. Verify name, location, and geometry before making changes.

2. Deleting a Field That Only Needed Correction

If the record remains useful, edit or preserve it instead of deleting it.

3. Dividing a Field Without Preserving the Original

Use Save As when the original may be needed later.

4. Creating a Cutting Line That Produces an Unusable Sliver

Inspect every divided polygon and its likely generated route before accepting the cut.

5. Treating Route Segmentation as Permanent Field Division

Segmentation selects a route proportion; it does not necessarily create separate reusable field records.

6. Moving One Boundary Point Without Checking Adjacent Lines

Every point affects the lines on both sides. Review the entire corner after fine-tuning.

7. Deleting a Boundary Point Without Inspecting the Replacement Line

The newly connected line may cut through the crop or another restricted area.

8. Setting One-Side Margins Before the Overall Margin

Later overall changes can affect the one-side adjustment. Set Overall first.

9. Using the 1.5 m Obstacle Distance Automatically

The supported range is a software control, not a universal safe-clearance rule.

10. Choosing the Nearest Start Point Without Reviewing the Entry Route

Nearest does not always mean safest or most efficient.

11. Enabling Boundary Spraying Without Checking Edge Overlap

Interior passes plus a perimeter pass can change total crop exposure.

12. Enabling Sided Spraying Around Sensitive Crops

Bypassing can create overspray and may increase phytotoxicity risk.

13. Manually Adjusting Direction While Auto Optimization Is Still Enabled

Disable Auto Optimization before attempting a manual route-angle change.

14. Accepting the Automatically Optimized Route Without Field Judgment

The controller may not know current wind, temporary hazards, crew position, or logistics.

15. Clicking Use Without a Final Task Review

Saving and loading a field do not replace pre-flight inspection and regulatory verification.

Troubleshooting DJI T100 Field Editing

Problem Likely cause What to check
Wrong field was opened Similar name or neighboring geometry Return to the field list and verify location, name, and shape.
Divided field has an impractical narrow section Cutting line was placed poorly Reposition the cut or use outside anchor points.
Original field disappeared from the intended workflow Save As was not used or wrong record selected Check the field list and preserve originals before reattempting division.
External anchor line does not divide the intended area Anchors do not cross the full field correctly Move both anchors outside the proper field sides and verify the connecting line.
Boundary point will not align accurately Map scale, imagery, or point selection is inadequate Zoom appropriately, verify current mapping, and use arrow-key fine-tuning.
Reset did not undo every field edit Reset applies to the current selected boundary point Review the current point and use field-level save/cancel controls as available.
Deleted point creates an incorrect boundary line Adjacent points connected directly Add or reposition a point to restore accurate geometry.
One-side margin changed unexpectedly Overall margin was modified afterward Reapply and verify Overall first, then One Side.
Routes are too close to an obstacle Safety distance or obstacle boundary is inadequate Adjust within 1.5–5 m and correct obstacle geometry; redesign if more clearance is required.
Start transition crosses an undesirable area Default nearest waypoint is not operationally suitable Select a different start point and inspect the entry path.
Boundary pass creates excessive overlap Route spacing, margin, or boundary setting is unsuitable Recheck Route and Boundary, effective width, and perimeter geometry.
Crop shows potential over-application risk in plan Sided spraying or bypass overlap may be inappropriate Disable the feature and reassess rate, crop sensitivity, and route behavior.
Manual route direction will not remain selected Auto Optimization may still be enabled Disable it before manual adjustment, then confirm the final state.
Segmented route selects the wrong area Slider proportion does not match the desired section Review active route lines and consider field division if permanent sections are needed.
Use button loads an unexpected task Wrong field version or divided section was selected Return to the field list and verify the exact saved name and geometry.

Ares Acres Recommended Field-Editing Workflow

  1. Inspect the real field and identify current boundaries, obstacles, excluded zones, and access points.
  2. Confirm the operator, pilot, aircraft, and mission have the required authority.
  3. Open Route Mode and select the correct field from the field list.
  4. Rename ambiguous records before creating additional versions.
  5. Preserve a valuable original before substantial changes.
  6. Use Field Division only when separate reusable fields improve the operation.
  7. Place cutting lines along logical operational breaks.
  8. Use outside crosshair anchors when existing boundary points do not support the required cut.
  9. Name and inspect every resulting field.
  10. Reopen the intended record with the Field Editing icon.
  11. Correct the outer boundary before changing route settings.
  12. Review obstacles and non-application areas after boundary changes.
  13. Fine-tune points systematically with Previous and Next.
  14. Inspect both connected lines after moving or deleting a point.
  15. Set route spacing from verified application performance.
  16. Set the Overall field margin.
  17. Apply One-Side margins only after Overall is final.
  18. Select obstacle-boundary safety distance within the demonstrated 1.5–5 m range and evaluate the real hazard separately.
  19. Choose a start point based on the complete entry and exit plan.
  20. Select Interior, Route and Boundary, or Boundary Only behavior deliberately.
  21. Choose clockwise or counterclockwise boundary direction.
  22. Avoid sided spraying when overspray or phytotoxicity risk is unacceptable.
  23. Compare route directions and turn geometry.
  24. Disable Auto Optimization before manual route-angle changes.
  25. Re-enable or compare Auto Optimization when useful, then inspect the result.
  26. Use Route Segmentation only when a partial route—not separate permanent fields—is intended.
  27. Save and clearly name the edited field.
  28. Click Use, then review the generated mission again.
  29. Complete aircraft, payload, positioning, weather, crew, and airspace checks.
  30. Launch only when the stored plan matches the current site and authorized operation.

FAQ: DJI Agras T100 Field Editing in Route Mode

When can I edit a field?

The DJI tutorial explains that a field can be edited while it is being planned or before it is used for an operation.

How do I find the field-editing controls?

Switch to Route Mode, open the field list on the left, select the desired field, and use the available field controls. To reopen detailed editing, select the field and click the lower-right Field Editing icon.

Can I rename a field?

Yes. Rename unclear or duplicated records so operators can identify the correct farm, block, crop, or section.

Can I delete a field?

Yes, but verify the exact record first. Deleting a saved field is different from deleting one boundary point.

When should I divide a field?

Field division is useful when a large or complex shape is easier or safer to operate as several separate reusable fields.

How do I divide a field?

Open Field Division and add cutting lines by selecting boundary points. You can also place crosshair anchor points outside the field and divide it with the line between them.

How do I preserve the original field?

Use Save As during the demonstrated division workflow. DJI explains that this preserves the original field and the fields divided from it.

Is route segmentation the same as field division?

No. Field division creates separate field geometries. Route segmentation selects a desired proportion of the generated route for an operation.

Can I edit obstacles and non-application areas?

Yes. The editing interface allows different field elements to be selected, including the field, obstacles, and non-application areas, although the source video primarily demonstrates field editing.

How do I fine-tune one boundary point?

Select the point in the Boundary Tuning panel and use the arrow keys. Use Previous and Next to move between adjacent points.

What does Reset do?

Reset cancels adjustments previously made to the currently selected boundary point. Verify the on-screen result rather than assuming it reverts all field edits.

How do I delete a boundary point?

Select it and click Delete, or double-click the point. Then inspect the line created between the adjacent points.

How do I finish a point adjustment?

Click a blank area to save the boundary-point adjustment and exit the point-editing state.

What is route spacing?

Route spacing is the distance between adjacent operation passes. It should be based on verified effective application width and the current material, settings, crop, and environment.

What is the difference between overall and one-side field margins?

Overall reserves a unified baseline margin around the field. One Side changes the margin near a selected boundary or range while leaving the other routes unchanged.

Which margin should I set first?

Set the Overall margin first. The tutorial warns that later changes to Overall can affect One-Side adjustments.

What is the DJI T100 obstacle-boundary safety-distance range?

The demonstrated interface allows a value from 1.5 to 5 meters. This setting must still be evaluated against the real obstacle, map accuracy, operating conditions, and applicable requirements.

How is the default start point selected?

The default is the waypoint closest to the agricultural drone. You can select Start Point and choose another location.

What does Route and Boundary do?

The aircraft completes the middle-field routes and then flies and applies along the field boundary to improve perimeter coverage when appropriate.

What does Boundary Only do?

It limits the planned application to the field boundary and does not provide full interior-field coverage.

Can I change boundary-flight direction?

Yes. The route can be configured to follow the boundary clockwise or counterclockwise.

What is sided spraying?

In the demonstrated workflow, sided spraying uses only selected outer sprinklers during lateral movement or selected inner sprinklers during bypassing. Confirm behavior for the installed system and current software.

Why can sided spraying be risky during bypassing?

DJI warns that it can create overspray. The tutorial recommends not enabling it for crops prone to phytotoxicity.

How do I change route direction manually?

Disable Auto Optimization, open Settings or the Course Angle control, then double-click a selected boundary for quick alignment, drag the direction icon, or use fine-tuning controls.

Should I use Auto Optimization?

DJI recommends it for automatic route-direction selection. The operator should still verify the result against real wind, terrain, obstacles, logistics, and application requirements.

How do I operate only part of a field?

Open Route Segmentation, move the slider to the desired route proportion, and click OK. Verify that the active route lines correspond to the intended area.

Does Part 107 alone authorize T100 spraying in the United States?

No. Part 107 generally applies to aircraft weighing less than 55 pounds at takeoff. T100 operations at or above that threshold require the applicable large-UAS authority, and covered agricultural dispensing operations also implicate Part 137. A Part 107 Remote Pilot Certificate remains relevant to the FAA’s current agricultural UAS pilot framework, but it is not the entire operational authorization.

What is an Agricultural Aircraft Operator Certificate?

An AAOC is the operator certificate required by Part 137 for covered agricultural aircraft operations unless the FAA grants specific relief. UAS operations can also require an exemption and other approvals.

What should I check before clicking Use?

Confirm the field version, boundary, obstacles, non-application areas, spacing, margins, obstacle distance, start point, boundary settings, sided spraying, route direction, segmentation, aircraft configuration, application parameters, weather, positioning, airspace, and applicable FAA and local authority.

Final Takeaway

Efficient DJI Agras T100 operations begin with accurate field data. Route Mode can generate a sophisticated mission, but it cannot correct a field that the operator has left inaccurate, poorly divided, badly named, or configured with unsuitable spacing and margins.

The field-editing workflow provides a complete set of controls: select the saved field, rename or divide it, preserve the original with Save As, refine individual points, review obstacles and non-application areas, establish route spacing, set the overall margin before one-side adjustments, choose an obstacle distance from 1.5 to 5 meters, relocate the start point, configure boundary spraying, evaluate sided-spraying risk, adjust route direction, segment the route when necessary, and save the final field.

The strongest field plan is not simply the one the controller accepts. It is the one that matches the current crop boundary, represents the real hazards, supports efficient flight, keeps application within the intended area, and can be executed under the operator’s actual FAA, label, state, and local authority.
