Coverage Area for US 10m Terrain in Google Earth
Earlier this week I asked someone at Google whether we could get details on the areas covered by the new 10 meter 3D terrain (or digital elevation model) data released last weekend for Google Earth. I had noticed some areas in the western US did not seem to have the high res areas. Before I jump on a plane to head home from California, I wanted to share this KML file (1.2 Mbytes) Google sent me in an E-mail last night. NOTE: the file has many tiles - so it may slow performance while turned on. The file shows that most of the western US got the update, but there are a few gaps here and there. So, now you know which areas have the new terrain. Google also confirmed the data came from a version of the USGS 10 meter terrain dataset.
If you haven't looked at the new terrain, I highly recommend it. Change the setting in your "Options" (or Preferences on the Mac) for "3D View->Terrain Quality" to a higher setting (set to the highest if your graphics card is reasonably fast and you have broadband). Then visit a mountainous (or varied terrain) area you know well. You'll be impressed by how realistic it looks now (especially if you saw the way it looked before). The data is now three to nine times higher resolution.
