The GeoMAPP effort aims to address the preservation of “at risk” and temporally significant digital geospatial content. Geospatial data layers containing information about land parcels, zoning, roads, and jurisdictional boundaries change regularly. Existing copies of these data are often at risk of being overwritten when updates or changes are made and these superseded snapshots of data are then lost for future use and analysis.
Project Detail - Digital Preservation (Library of Congress). The GeoMAPP project is exploring ways to expand the capabilities of state governments to provide long-term access to geospatial data. The project is bringing together geospatial and archival staff in multiple states to identify, preserve, and make available temporal and superseded digital geospatial data with ongoing value. A key approach will include testing a geographically dispersed content-exchange network for the replication of state and local geospatial data among several states to promote preservation and access.
