GIS Data

Find datasets for GIS mapping applications recommended by the library's subject specialist. It features current and historical data in the library’s collections and in public repositories.


The data layers that you can download here are good for ArcGIS. Some of the data the Library bought for our users needs. That data requires your login and password to access. Other data are available via the Web. Those types of data may require that you register before downloading information. As this page is always a work in progress, if you don't see what you need, please contact the Evans Map Room for assistance.
