I use Litchi and VLM interchangably on my PC to build and check Waypoint Missions I fly and visualise them with Google Earth.
I got caught a couple of times when Namirda’s Google API quota got exceeded so I recently went thru the process of getting my own. Works fine as far as Mission design is concerned.
I usualy check the “Altitude Profile” graph to get a guide of what sort of ground clearances I have but with my own Key, the Altitude Profile isnt created. Delete the Google API Key and revert to Litchi and I get the profile.
Years ago I think this was identfied in Mavic Pilots but no solution or reasoning was found.
Any new light on this for current versions of everything ?
