Yes, it can, though whether it's sensible to do so would depend on what you wanted to use the information for. You can use the properties interface (either by telnet or http) to set a position, then read back the ground elevation - the null fdm is ideal for this. We also have a tool which can load scenery tiles and return elevations - it's far more efficient for doing this in bulk. The values you get are of cource the elevation of the scenery, which may vary from real world values - if that's what you want then you're probably better off reading values directly from SRTM or a similar source.
