Yosemite National Park @ 1/3 Arc Second
Yosemite National Park in California. El Capitan in the left foreground and Half Dome seen in the background. 1/3 Arc Second (~10 meters per point) Elevation Data and satellite orthoimagery obtained from the USGS seamless server. Generated using custom software written in C++ with the blue sky background added using GIMP.
Yosemite National Park @ 1/3 Arc Second (2)
Yosemite National Park in California at a similar angle (slightly elevated) to the previous model and using Hypsometric Tinting instead of Satellite images. El Capitan in the left foreground and Half Dome seen in the background. 1/3 Arc Second (~10 meters per point) Elevation Data obtained from the USGS seamless server. Generated using custom software written in C++.
jDem846 Example: Google Earth
Example of a two dimensional DEM rendered using jDem846 and loaded into Google Earth as an layer overlay. Subject is Mount St. Helens in Washington using 1/9 arc second raster data provided by the USGS.
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 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.
