UCR Library provides access to a wide variety of maps, atlases, aerial photos, and geographic data.

Maps

We hold historical, thematic and road maps, as well as atlases. Our United States Geological Survey (USGS) topographic maps come in various scales for the entire U.S. Geological maps can also be found online through the U.S. Geological Publications Warehouse or the California Geological Survey.

Many maps are cataloged in the Scotty (UCR) catalog and the Melvyl (UC) catalog. Search using the type of map and the geographic area (e.g. quadrangle name) as keywords and modify your search to limit to maps.

We also hold captured German and Japanese maps from the World War II era. For questions about our collections of maps please contact Manuel Urrizola

Geographical Information Systems

Geographical Information Systems (GIS) make maps come to life by storing, analyzing, and relating spatial and geographical information. To support GIS, we provide ArcGIS software on computers in the Orbach Science Library Map Room and Learning Commons computers, as well as Learning Commons computers in Rivera Library. We can help you identify, obtain, and organize data sets for your research - email us at dataconsult-lib@ucr.edu.
