Archived GIS Data

GIS Home | GIS Data

Archived GIS Data includes previously available data in ArcInfo Export File (.E00), Shapefile, and File Geodatabase format. Archived GIS data files are not updated. Data in the older ArcInfo Export File format represent previous versions of data currently maintained by DEP in Geodatabase format. ArcInfo Export files can be converted and imported to ArcInfo coverage format for use with the current version of ArcGIS Desktop software. A few archived data originated as Shapefiles instead of ArcInfo coverages and and were subsequently converted to Geodatabase format. Visit to the GIS Data page for more current information.
