when you click a point on the map, information about the FIS frequency and the airspaces appears. Would it be possible to show the terrain elevation at that point as an additional piece of information? This would both be generally helpful for the selected overflight altitude at that point, and because some airspaces or NOTAMs require a minimum height above ground (AGL) for overflight rather than an altitude above mean sea level (AMSL). With that info it would be easier to choose a suitable and correct overflight altitude.
