In performing an Internet search using the term “GIS,” a user discovers a myriad of sites. Some sites contain one or two links and others have multiple links to a vast amount of excellent information.
The resources listed below are some that I use for Geography and GIS Internet training classes. I chose sites with a multitude of links to other areas. These sites cover such areas as government, education, and commerce. Included are resources for diction aries, newsgroups, mail lists, and periodicals to show the spectrum of material available in GIS. So enjoy and have fun creating your world!
