Litchi y virtual licthi missions

[JORGE SM]

As I said in my presentation, I have a great mavic pro and I have already tried DJI GO 4. But I come from an F450 and a tower. With a tower I could plan missions and with DJI GO it is more complicated. That's why he has decided to buy Litchi, and I'm trying to register missions and then see them on google earth. All that is correct, so you can see where you are going to travel and if there is any obstacle. For the purposes of use, it has been corrected. This can happen if between wp and wp there is an obstacle. But after practicing, I read something about litchi virtual missions, which I think is a fabulous tool, that you can see the flight almost as real. The application of a CSV file is already available, it is not correct. It does not fly around the tower. My problem lies in the concept of heights, in the absolute relationship with the ground, etc. Will there be a thread where I explain step by step a simple configuration to start? I've seen videos on YouTube and the Google Earth flight looks fabulous.
In the tests that I have done, the waypoints appear very high and when viewing it with virtual litchi missios in google earth, the vision is very high.
thank you very much
