What happens when the
height_amsl() function is ‘corrected’. Does this mean that the height returned is the terrain height above the home location rather than above mean sea level?
find the terrain height in meters above sea level for a location return false if not available if corrected is true then terrain alt is adjusted so that the terrain altitude matches the home altitude at the home location (i.e. we assume home is at the terrain altitude) */ bool height_amsl(const Location &loc, float &height, bool corrected);
