The UO Libraries has extensive GIS and mapping resources for UO users. This page focuses on resources related to the Portland Metro and Greater Portland area, since these are important to UO users in Portland.
Please note: Our academic workstations for UO users are equipped with ArcGIS software to read and analyze datasets. UO students and faculty can also install the full ESRI suite on their home or office computers.

If you are new to using ArcGIS software, you may wish to use some online tutorials. One good tutorial is provided by the Pennsylvania Geospatial Data Clearinghouse, here. Our own tutorials cover the following topics for ArcGIS 10.1:
The UO MAPS and GIS Library has large collections of paper maps of the Portland area. Not all maps in the collection are cataloged, so it's best to contact the map librarian, Kathy Stroud, to find out if we have what you're looking for. Some (but not all) maps can be sent to Portland for UO users.
- To find Portland-area maps in the catalog: use call numbers or search words.
- Try a subject search for Portland (Or.) -- Maps.
- You can limit your search by choosing "Maps & Atlases" from the drop down menu, instead of "Entire Collection."
- Maps of Oregon can be found in the call number range G4290 to G4299. City maps of Portland generally begin with G4291.P.
- The Building Oregon collection includes photographs of buildings all over the Portland area, which have been added to a Google map mash-up.
- The Aerial Photography Collection at the University of Oregon Library is the largest repository of vertical aerial prints in the state of Oregon. Find out more at the website.
