How Do I Find GIS Data?
Until further notice, access to the Map Library is limited to library staff only.
For access to many of our maps, aerial photographs, and other physical materials, please search for the item in Libraries search. Sign in and place a “Get It” request and you can pick up items at one of our four open buildings — Wilson, Walter, Health Sciences, and Magrath libraries — or have them delivered to your office or residence hall.
For access to non-circulating materials or for in-depth research assistance, please send an email to email@example.com.
While this list is not exhaustive , its goal is to identify and provide access to as wide a variety of online GIS data and resources as possible.
