Our Earth
Rendering of the Earth. This was done using new experimental C++ code that is being put together as a possible successor to jDem846. It has improved algorithms and now integrates OpenGL for hardware acceleration. This new code is considerably faster and much more memory efficient than the Java-based project. Elevations are exaggerated by about 50 times to better visualize terrain features, and cloud and atmospheric elevations are rather arbitrary.
Sources:
- Elevation Data is derived from the Shuttle Radar Topography Mission 30-arcsecond data (SRTM30), the Radarsat Antarctic Mapping Project Digital Elevation Model Version 2 (RAMP2), and the GEBCO_08 bathymetric raster from General Bathymetric Chart of the Oceans.
- Satellite imagery provided by the NASA's Earth Observatory Blue Marble project.
- Global clouds are from the NASA Visible Earth catalog.
