Richard,
The NASA SRTM seems as if it would suit my purposes, except that using
r.in.srtm I get a lovely image with no elevation data. So r.what comes
up with latitude, longitude, and null, eg:
150 | -34 | | *
also consider the option to import ASCII SRTM data usign r.in.gdal in GRASS.
the projection is lat/long (WGS84, epsg id = 4326), while the elevation data
are in meters.
Regards,
Marco
