Mission Control supports multiple file formats for importing and exporting missions. This lets you share missions between different GCS applications, convert data for GIS tools, or back up your plans.

​
Supported Formats

FormatImportExportDescription
.waypointsYesYesArduPilot standard format. One waypoint per line.
.planYesYesQGroundControl JSON format. Includes waypoints, geofences, and rally points.
KMLYesYesKeyhole Markup Language. Used by Google Earth.
KMZYesYesCompressed KML (zipped).
CSVYesYesComma-separated values. One waypoint per row.
GPXNoYesGPS Exchange format. Compatible with many GPS tools.

​
.waypoints Format

The ArduPilot .waypoints format is a plain text file with one mission item per line. It is the native format used by Mission Planner and ArduPilot SITL. 
QGC WPL 110
0	1	0	16	0	0	0	0	-35.363262	149.165237	584.000000	1
1	0	3	16	0.00000000	0.00000000	0.00000000	0.00000000	-35.361540	149.164475	100.000000	1
2	0	3	16	0.00000000	0.00000000	0.00000000	0.00000000	-35.360068	149.168137	100.000000	1
Each line has the fields: sequence, current, frame, command, param1-4, latitude, longitude, altitude, autocontinue.

​
.plan Format

The QGroundControl .plan format is a JSON file that can contain waypoints, geofences, and rally points in a single file. 
{
  "fileType": "Plan",
  "geoFence": { ... },
  "groundStation": "ADOS Mission Control",
  "mission": {
    "items": [ ... ],
    "plannedHomePosition": { ... }
  },
  "rallyPoints": { ... },
  "version": 1
}
This format preserves the most information, including complex mission items, fence definitions, and rally points.

​
KML / KMZ

KML (Keyhole Markup Language) is an XML format used by Google Earth and many GIS tools. Mission Control can import KML files as waypoint paths or polygon boundaries. Import behavior:
  • <Placemark> with <Point> elements become waypoints
  • <Placemark> with <LineString> elements become a connected waypoint path
  • <Placemark> with <Polygon> elements become boundary polygons for pattern generators
Export behavior:
  • Waypoints are exported as a <LineString> with <Placemark> markers
  • Altitude mode is set to relativeToGround
KMZ files are ZIP-compressed KML. Mission Control handles the compression and decompression automatically.
KML uses longitude-latitude order (lon,lat,alt), while Mission Control uses latitude-longitude internally. The parser handles this conversion, but be aware of the difference if you edit KML files by hand.

​
CSV

A simple spreadsheet-compatible format with one waypoint per row. Columns: 
seq, command, frame, lat, lon, alt, param1, param2, param3, param4
Import:
  • The CSV handler detects the column layout from the header row
  • Missing columns use default values
  • Coordinates must be in decimal degrees
Export:
  • All waypoints are written with headers
  • Compatible with Excel, Google Sheets, and any CSV tool

​
GPX

GPX (GPS Exchange Format) is an XML format widely used by hiking, cycling, and outdoor navigation apps. Export only. Mission Control exports the flight plan as a GPX track with waypoints. This is useful for visualizing your planned route in GPS tools or on hiking apps.

​
Parameter Files

Mission Control also handles FC parameter files through a separate flow:
FormatDescription
.paramArduPilot parameter file (name=value pairs)
.paramsAlternative parameter extension
These are used in the Parameters panel for importing and exporting flight controller configurations, not mission waypoints.

​
Plan Library

The Plan Library stores missions locally in your browser (IndexedDB). You can:
  • Save any mission to the library with a name and description
  • Load a saved mission to replace the current plan
  • Delete missions you no longer need
  • Browse saved missions with preview thumbnails
The library persists across browser sessions. It is local to your browser and not synced to the cloud by default.
Export important missions to a file as a backup. Browser storage can be cleared by the user or the browser itself.

​
KML Overlays

In addition to importing KML as waypoints, you can load KML/KMZ files as map overlays. This is useful for:
  • Visualizing property boundaries
  • Showing restricted airspace shapes
  • Overlaying survey area outlines from other tools
  • Displaying reference paths from previous flights
Overlays appear on the map but do not become part of the mission. They serve as visual references while planning.

​
Importing a Mission

1

Open the Plan tab

Navigate to the Plan tab.
2

Click Import

Use the mission actions menu (or drag and drop a file onto the map).
3

Select the file

Choose a .waypoints, .plan, .kml, .kmz, or .csv file from your computer.
4

Review the imported mission

The waypoints appear on the map. Review and edit if needed before uploading to the FC.

​
Exporting a Mission

1

Create or load a mission

Make sure you have waypoints in the planner.
2

Click Export

Open the mission actions menu and select the export format.
3

Save the file

The browser downloads the file. For KMZ, a compressed archive is generated automatically.
