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.

Online Map Collections and Historic Maps

Many libraries or other collections have taken the time to scan historic maps, which can be used in a GIS system once they are georeferenced--some of these collections even have pre-georeferenced maps!

Databases

The UM Libraries subscribe to some databases that include maps...

Atlases

Gazetteers

Gazetteers are wonderful resources - they list place names (this can be particularly handy for historical research, since place names do change over time) and provide latitude and longitude coordinates.  They also give information such as square mileage, length, and height for various geographical features.
