The Clean Earth overlays replace the default Google Earth textures at high altitudes for the entire Earth. Instead of seeing inconsistent strips of different aerial/satellite photography that look very unrealistic, you can now see a nice clean natural looking Earth surface. The Clean Earth overlays use hill shading to exaggerate the vertical elevations of . . . → Read More: Clean Earth
This terrain map of California was created by combining the NASA Blue Marble imagery with the global elevation data from the Space Shuttle Radar Topography Mission (SRTM). The combination of these two data sets creates an amazing new way of viewing the Earth’s topography and landforms.
Major Land Resource Areas (MLRA) and Land Resource Regions (LRR) are areas of the United States with similar geography (physiography, climate, geology, etc.), as defined by the US Department of Agriculture and the Natural Resources Conservation Service. These areas are used for large scale interstate planning. There are approximately 280 MLRAs in the . . . → Read More: Major Land Resource Areas of the United States
