GIS Data and Websites

Where can you get data to use in a GIS? The UM Libraries have geospatial data in the collections, many websites have free data, and data can also be purchased.

Commercial Data Providers

Looking to buy some GIS data?  Here are some of the biggest providers.  But remember, the Libraries may already have what you need!  Be sure to check the catalog first.  Also, please be aware of licensing restrictions if you buy and use data.
