Shaded Relief Map of US Terrain in Google Earth
A GEB reader wrote me to tell me of his project over the holidays to create a dynamic KML which shows Shuttle Radar Topography Mission (SRTM) digital elevation model in a shaded relief format for North America (NOTE: GE 4 is required). Jiro implemented this using KML 2.1 region tags so you get more detail as you zoom in, and it works very quickly. He also has used Google Picasa web servers and managed to parse the resulting location of all the images which really helps since the images end up being on many servers. The entire database is just under 1 GBtyes. But, you don't need the technical stuff. Just go download this shaded relief map 
and check it out. Jiro points out it is possible to do the whole world since the SRTM mission data is available for the whole Earth. Great job Jiro, this is amazing!

You can see the srtm data as custom tiles in a google map mashup at www.shaded-relief.com

Actually, the SRTM data covers only the region between 56°S and 60°N. Most of the Earth is covered, but places like Alaska, northern Canada, northern Europe, northern Siberia and whole Antarctica don't have data.
