Digital Elevation Model of our Earth
The flat DEM was generated using custom software (jDem846; not yet released) I have written in Java using algorithms derived from my earlier masters thesis software. The data is from NOAA ETOPO1 land elevation and ocean bathymetry at 1 arc minute. (see previous image in photostream).
The image was mapped to a sphere using the GNU Image Manipulation Program (GIMP).
The software is not yet feature complete as I plan to add support for ESRI shapefiles, additional raster input formats, and some limited three-dimensional rendering options.
The full size image (~120MB) is available upon request.
