Sources of Data on the Internet

Data Resources on the Web - websites with downloadable data

Links to other GIS labs' on-line data resource web pages

On-line Mapping Applications - sites from which you can generate or view maps on-line. Includes several examples of easy-to-use data available at the University of Michigan.

Off-line Sources of Data

The NSDS lab has a variety of digital data on CD for the United States and the World. Much of this can be found using the University Library Spatial Data Catalog and in Mirlyn. We also have data on the NSDS lab's local data server, primarily on the T drive. We will be happy to assist you in locating data.

On-line GIS Data Request Form - You may use this if you prefer to make a request for data using a form rather than sending us e-mail.

Have data to share? Submit data/metadata to the campus's spatial data catalog. See Metadata for Digital Spatial Data for more information.
