- simple tool for mapping with drone, a free alternative to commercial apps. You need Litchi and a compatible drone.
Tutorial: youtube
Important notes:
1. Ff you save CSV file:
Litchi stops at each waypoint. To get around this, I implemented an "advanced" mode - default. With the additional waypoints, photos will be taken only during a straight path, at a constant speed, and the drone will turn smoothly without stopping.
For this feature to work, you need to select "Curved turns" in the app settings (or Litchi Hub) before flight. Otherwise, the drone will stop at each waypoint.
Look at the created path and adjust "Buffer" setting to cover your area of interest.
It's a the Litchi feature (Straight lines) which I can't get around or switch in the csv file.
After creating a CSV file you have to open it in Mission Hub and save in Litchi Cloud (Litchi itself doesn't accept csv files).
2. If you choose binary file:
You can save the binary file directly in the Litchi folder. It's Android/data/com.aryuthere.visionplus/files/missions/__users/USERNAME. I created a button to get you there.
Next, you can just open Litchi and select the file from the list. No need to change settings or use Mission Hub.
Unfortunately it works only in Android 10 and lower. If you have Android 11-12 you still need to save the binary file in Downloads (or another public) folder and move it using file manager. Or, you can still upload it using Mission Hub (like csv files).

Release notes:
1. Added multiple waypoint mode (mode 4) - needen for AGL calculation when flying over hilly terrain. If the line is more than 60 meters, points are added (in increments of 30). This allows Litchi to accurately determine AGL heights.
Important: after loading a mission in Litchi, click "batch edit" icon, then "Select all / edit". Turn on "Height relative - ground" and set the desire height. Now Litchi will calculate all waypoints relative height.
2. Added option to show waypoint numbers (just to show all waypoints).
Known bug:
I think there is something wrong with Litchi making photo each x seconds (time interval). If you set photo mode to "Single photo", Litchi will make
photo eache x seconds (for example every 2 seconds) but it sometimes doesn't work correctly and my tests shows that delay is sometimes 4 seconds.
You can alternatively set Litchi (manual settings before mission) to make photo every 2 seconds, it will be independend of the mission, but it's reliable. The drawback is that photos will also be taken at the turns. I can't solve it for now, I think it's Litchi's fault, I need to test it more.
