Request: implement the option to choose between SRTM and Google Earth.

In many areas Mission Planner returns ground heights (SRTM) that deviate (incorrectly) from the values that you can see in Google Earth (usually more updated and more corrected).

So, it would be possible to implement a function that allows you to choose whether to use the heights derived from SRTM or those ones derived from Google Earth?

It also would be possible to implement a function that allows you to choose whether to use SRTM data or Google Earth data when "Verify Height" is enabled ?

Thanks.

Start by locating the code that retrieves SRTM ground heights and the path used when "Verify Height" is enabled. Then determine how Google Earth height data could be accessed and selected alongside SRTM, including the expected behavior for both normal height retrieval and verification. Done means users can choose either source in both contexts.
