GIS Data

About this collection

The GIS Data Collection is a product of the Geospatial Multistate Archive and Preservation Partnership (GeoMAPP) project, which aims to address the preservation of "at risk" and temporally significant digital geospatial content.

This online collection currently consists of a subset of "demonstration" datasets or purposely identified datasets to capture as part of the demonstration portion of the project. As such, not all of these datasets are currently available online. The dataset categories include local and state government datasets, orthoimagery, centralized datasets (Framework and Non-Framework data), project files and digitized maps. The GIS Data collection spans the years 1947-2009, with the bulk of the items ranging from 1999-2009.

Additional datasets are available that are not currently listed in this online GIS Data Collection. For information on the location of these materials, please contact the Government Records Branch of the State Archives and consult the GIS Data Collection online finding aid.
