title_body: Vertical Flight Paths I've been searching around for software to allow a vertical flight plan. For example I want to flight 50m across a building at 20m AGL. Then drop 1m and fly back 50m. So on and so forth. I've read a bit into DJI, DroneDeploy, and Pix4D, but haven't been able to find anything. I've read something about double grids, but I believe that is for 3D models? I am not trying to capture a 3D model. I know that in at least Drone Deploy you can create multiple flight paths, but you have to land and restart for each altitude drop. I am also not taking any pictures. Looking for just the flight path. This could be done manually, but I'd prefer it to be automated.
  Does anyone have any suggestions?
upvoted_answer: There is a software called UgCS which I believe should fit your requirements. It allows you to create waypoints with precise location and altitude. There are options like terrain following which allows the UAV to maintain a relatively constant altitude above ground level, a Facade scan tool which allows you to plan a flight path along a vertical plane at a certain distance from a wall, or there is the option to easily create custom waypoints with specific altitudes as shown in this flight path:
