Spatial Data Sources
About this list: This is a selected list of datasets and internet sources for spatial data. The purpose is to include reliable sources of commonly-sought data, most of which is available free of charge, suitable for use with geographic information systems. If you have comments, corrections or suggested sources, please contact the Map Collection.
ASU Libraries' Data
The Map Collection has spatial data available for Arizona, other U.S. states, the United States, and the World. Most of the datasets in the Collection are available on CD-ROMs; the Collection's primary CD-ROMs are listed below. Other datasets can be searched in the Library Catalog. Some datasets, such as U.S. Census information, are held in Government Documents on the 3rd floor of Hayden Library. For more information on available data, please contact the Map Collection at (480) 965-3582.
Note: Some CD-ROMs are non-circulating and must be used within the Map Collection.
