| 説明 | 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 bedrock 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) with some brightness and contrast adjustments.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 flat image (~100MB) is available upon request. |
