Hello ther,
I am trying to perform a Terrain Following flight using a VTOL. I followed the steps from here Terrain Following for Plane. TERRAIN_ENABLE = 1 and TERRAIN_FOLLOW = 1.
I loaded the terrain data to the APM/TERRAIN folder in the SD card, but when I want to check the current altitude (when preparing the flight plan), no terrain data is available. See figure below:
It happends also when GPS i fixed, with more than 10 satellites. Any help on this issue?
Thank you so much,
Eduard Miralles
