I am currently trying to determine the reference frame of the SRTM data. Is it MSL (Mean Sea Level), or HAE (Height Above Elipsoid)? It doesn't seem to match Google Earth (assumed to be MSL). Thanks - OBTW: I'm not complaining, as for most users, the data will be consistent among "sets" (i.e. something you want an elevation profile of), and 30' of elevation offset is no big deal. Thanks, Great feature.
