GIS Data

This table not only gives link to data you can download, but it also gives links to states where they have created their own mapper. You pick from the data available and map it. You then have a choice of saving the resulting map and/or printing it. Not every state has a mapper, but where they do, a link is provided.

Please note: you cannot cross state lines when using one of the mappers.

Thanks to Linda R. Zelmer, Map Librarian at Western Illinois University for the online atlas part of this list.
