Aircraft and camera

Flight line spacing and photo interval use this camera. Phantom 4 Pro plans export a Litchi CSV you can fly, and the Android flight app (MSDK v4) can connect to the Phantom 4 Pro too.

Android app

Download Android flight app

This is the Drone Mapper flight app, not the Piletally measure app. Uninstall any older build of this flight app first, then install this APK. Keep DJI Fly closed while this app is connected to the aircraft.

Uses Mavic Air 2 12 MP (4000×3000), 24 mm-eq, 84° diagonal FOV. Speed is capped so photos stay at least 2 s apart. Altitude is capped at 400 ft (FAA Part 107).

Export

Load the JSON in the Android flight app, or save to my list while signed in and it will show up in the app for the same account. KML opens in Google Earth. Litchi CSV is a bonus — Air 2 has no DJI waypoint API, and Litchi also flies it with virtual sticks.

Start with step 1: tap Upload photos and pick your pictures. The upload starts as soon as you pick them.

1. Upload photos

Pile name

How to take the photos

Walk or fly all the way around the pile.
Take a photo every couple of steps so each one overlaps the last.
About 40 photos is good. You need at least 30. Max 50 photos per job for now.

2. Make the map

After the photos are in, tap Make map. It can take a while, so it does not start on its own.

3. Tap the pile

When the map is ready, tap the pile on the map. Piletally outlines it and shows the volume.

I already have a height map

Made the map in other mapping software? Open its height map (a DSM .tif file) and, if you have it, the map photo.
