This site, created by Tom Patterson, started out as a resource for cartographers creating shaded relief, panoramas, land cover, and related raster art on maps. It has since grown to include his other cartographic interests and has become a repository for his maps, all of which are in the public domain. It also includes articles and tutorials on the topic of cartography.
