Tools for Drones

    How to use

    Step-by-step guides for each tool

    KML Converter

    Steps

    1. 1Upload a KML or KMZ file.
    2. 2Check the polygons shown on the map and in the list.
    3. 3Select a polygon in the list to zoom to it.
    4. 4Download all polygons, or one at a time, as Pilot 2-ready KML.
    5. 5Copy the KML to the root of the controller's SD card and import it.

    Tips

    • •The converter strips unsupported KML elements that cause DJI Pilot 2 to reject files.
    • •Multi-polygon KMZ files are split into separate KML files for individual import.
    • •Polygons without names will use the original filename as their base name.

    Send to Drone

    Steps

    1. 1Upload your KML or KMZ files.
    2. 2Get a 5-character transfer code.
    3. 3On the controller, open 4dr.one in the browser.
    4. 4Enter the code and download the files.
    5. 5Import them in Pilot 2.

    Tips

    • •DJI waypoint missions (KMZ with waylines) are detected and sent as-is.
    • •The compatibility check strips styling, metadata, and complex structures that can cause issues.
    • •Transfer codes expire after 24 hours for security.
    • •Use the feedback link if files don't work as expected after the compatibility check.

    FlightHub Converter

    Steps

    1. 1Upload a DJI Pilot 2 KMZ waypoint mission.
    2. 2Check the detected aircraft and payload.
    3. 3Select the target Dock aircraft.
    4. 4Convert and download the KMZ.
    5. 5Import it into FlightHub 2.

    Tips

    • •The tool modifies both .kml and .wpml files inside the KMZ archive.
    • •Raw aircraft and payload codes are displayed for verification and debugging.
    • •Only DJI Pilot 2 waypoint missions (containing waylines.wpml) are supported.
    • •You can use Send to Drone integration to transfer converted files directly to your controller.

    Area Splitter

    Steps

    1. 1Upload a KML or KMZ with your survey area.
    2. 2Pick the polygon to work with if the file has several.
    3. 3Set a section count, or draw cut lines on the map.
    4. 4Check the sections and their areas.
    5. 5Download each section, or all of them as a ZIP.

    Tips

    • •Plan your slices to create roughly equal areas for balanced multi-drone operations.
    • •Each slice is color-coded for easy identification on the map.
    • •Area statistics are shown for each resulting polygon section.

    Mission Splitter

    Steps

    1. 1Upload a DJI Pilot 2 KMZ mission.
    2. 2Review waypoints, distance and flight time.
    3. 3Choose how to split it.
    4. 4Preview the parts on the map.
    5. 5Download each part as its own KMZ.

    Tips

    • •Use this tool when your mission exceeds DJI Pilot 2's waypoint limits.
    • •Split points are calculated to maintain logical mission flow.
    • •Consider battery life and overlap when determining split sizes.

    SAR Planner

    Steps

    1. 1Pick a search pattern.
    2. 2Draw the search area, line or datum on the map.
    3. 3Choose your drone and camera.
    4. 4Set altitude, speed and spacing, then check the summary.
    5. 5Send to your drone or download the mission.

    Tips

    • •Video recording starts automatically at the first waypoint and stops at the last — included in every export format.
    • •Search spacing is the distance between parallel passes (or resampled points on Shoreline). Smaller = tighter coverage but more battery.
    • •For Shoreline missions, set Path Position to Left/Right with an offset to fly safely alongside cliffs, rivers, or roads.
    • •Camera Direction 'Towards feature' auto-yaws the gimbal perpendicular to the line — useful for inspecting shorelines or escarpments.
    • •Terrain Contour Search (DEM-based) is coming soon — not the same as the Shoreline pattern.

    GSD Calculator

    Steps

    1. 1Select your drone or camera.
    2. 2Enter your planned flight height.
    3. 3Read the GSD, footprint and coverage.
    4. 4Adjust height until the GSD meets your survey requirement.

    Tips

    • •Lower GSD values mean higher resolution imagery.
    • •Common survey requirements: 2-3 cm/px for mapping, 1 cm/px for inspection.
    • •Flying higher increases coverage but decreases resolution.
    • •The calculator supports 30+ drone and sensor combinations.
