I have a client that is building a new 25 mile road in the middle of the forest. They have mapped it they just want me to fly the 25 mile length capturing video in 4 mile segments. I was thinking of using Litchi waypoints. Does anyone have any suggestions on possibility different apps to do a job like this? I have a P4 and was planning on following aircraft on 4 wheeler. Any other suggestions are welcomed. TIA
