[talk-au] NASA completes another elevation map
Apparently NASA and the Japanese space agency has released another elevation map for the Eath which has 99% coverage using a 98ft grid, so roughly 9x the resolution of SRTM's ~90m grid. BBC news have it covered here: http://news.bbc.co.uk/2/hi/science/nature/8126197.stm There's also discussion on Slashdot: http://news.slashdot.org/story/09/06/30/1650208/Most-Complete-Topographical-Map-of-Earth-Complete?art_pos=11 I wonder how long it will be before OSM will be able to integrate this data... It would be nice to have a higher resolution dataset so the topo lines can be smoother and more accurate. Anybody know how this data can be downloaded?

There was comments about this on the main talk list and before you can download the data you have to a number of things including that you agree to only distribute the data inside your own organisation or in times of disaster. Although I'm sure someone will end up pinging NASA et al to see if they can get a more accommodating license from them. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

Google turned up this. Out of curiousity I'm downloading some tiles from the Japanese link of my area. http://asterweb.jpl.nasa.gov/gdem.asp ASTER Global Digital Elevation Model (GDEM) The GDEM is available for download from NASA’s EOS data archive and Japan’s Ground Data System. ASTER Global DEM and archived data are only available through the links above. This ASTER product is available at no charge for any user pursuant to an agreement between METI and NASA.

If your using gpsdrive or gosmore then you can integrate it for your own use anyway. Details are in the osm wiki. Cheers Ross Hmm, that's a bit annoying. The more restrictive license is probably due to the data being collected by Japanese equipment rather than purely NASA gear. Aw well, give it time. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
