The Other Shaded Relief Site

The Shaded Relief world map should not be confused with Tom Patterson’s Shaded Relief site (previously); instead, it’s a Google Maps mashup with a custom layer. “We have created a custom layer using SRTM30+ and SRTM90 DEMs and used VMAP0 sea, lake and river overlay to create a shaded relief layer,” Jon Parker writes. “We have uploaded up to zoom level 8 completely and have the Northern hemisphere of level 9 completed — Southern Hemisphere in progress — just 60,000 tiles to go. […] We will also be having a go at zoom level 10 for the shaded relief which is approx. 500,000 tiles.” (See also.)

If you like shaded relief maps, check on the 1.4 version of World Wind. Its sunlight shading option combined with a solid-color map layer (like the USGS top or the Virtual Earth road map) means you can make instant shaded relief maps of anywhere in the world, including the bottom of the ocean. The terrain exaggeration and light color, azimuth, and direction are all adjustable on the fly.
