Geospatial data for the Vegetation Mapping Inventory Project of Effigy Mounds National Monument

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2006-03-01T00:00:00Z
The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. We converted the photointerpreted data into a GIS-usable format using three fundamental processes; (1) geo-reference, (2) digitize, and (3) database enhancement. The resulting map products are two ArcInfo coverages (the Yellow River Unit and environs and the Sny Magill Unit and environs), each projected in UTM, Zone 15, using NAD83.
