The National Geographic web-link has multiple resources for all types of cartographic themes. It’s a good site to visit for examples of physical geography maps, regional geography maps, cultural geography maps, and current issues maps. Recent issues of the magazine are on-line, and they also have an on-line map store for area mapping.
The U.S.G.S. web-link is a good resource for digital data, and has maps for geological and natural sciences. Digital data is available for purchase, and the U.S.G.S. link also provides create-your-own-map interactivity.
The separate link to class e-mail geog590@yahoo.com is provided for homework assignments and project related notes.
