[OSM-talk] Shuttle Radar Topography Mission

[Thom Shannon]

Has anyone tried to use data from the Shuttle Radar Topography Mission 
to add detail to osm maps? It could be used to add approximate altitude 
data to nodes, or for giving a shaded background to maps showing 
mountainous regions.

A lot of nasa material has a very relaxed licence or is public domain. 
I'm not sure if it's covered by nasa copyright guidelines 
(http://www.jsc.nasa.gov/policies.html#Guidelines), and I don't think 
they're compatible with CC-By-SA. Still it could be used to make shaded 
backgrounds for open street map that are simply licensed differently?
