The DNR's NRGIS Library has been retired.

The Library's data has been merged into Iowa Geodata (Click Here), the State's clearinghouse of geospatial data. This is a collaborative space for users and publishers of geospatial data about Iowa.

Proposed in 1988, and implemented by 1993, the NRGIS Library quickly became one of the largest and most used repositories of GIS data in the country. Many thanks to the early developers and promoters, including Jim Giglierano, Bernard Hoyer, Kevin Kane, and Joost Korpel.

Thanks for all the visits and we are glad to have promoted open data for all these years. We look forward to serving you just as well, or even better at Iowa Geodata:
