Andrew Tridgell 9ca65602c6 AP_Terrain: added dataflash logging 2014-08-06 17:59:19 +10:00
Andrew Tridgell 147a7b8b69 AP_Terrain: added extrapolation based on last available data 
if we run out of terrain data then extrapolate using the last
available terrain height at the AHRS position. This can be used to
cope with GCS outages over long distances where the terrain data isn't
preloaded
