Earth Relief Globe
Here is a relief globe that includes the sea bottom.
It was created using the program "globe" by DJ Moews available under the GNU GENERAL PUBLIC LICENSE. Globe can be downloaded from http://djm.cc/dmoews.html.
The data is derived from the Scripps SRTM30_PLUS V8.0 data set which is copyright but can be used for non-commercial purposes - see srtm30plus_copyright.txt for the license. The derived data set, srtm30plus, the input to globe, is at http://djm.cc/dmoews.html.
Two stl files are provided:
n_hemisphere.stl and s_hemisphere.stl
When printed and joined together the two files produce a globe about 5 inches in diameter. The red version in the image above was scaled by 0.8.
