Download ESI Maps and GIS Data

On this page, you can download free Environmental Sensitivity Index (ESI) maps and data in a variety of formats:

• PDF (Portable Document Format) files.
  
• Geodatabase format with an ArcMap map document (.mxd). (The date following the geodatabase links shows when modifications were made to the data tables and/or map document only. The underlying data content is not changed with the update.) We've developed several ESI Tools to help you work with the geodatabase files.

• ESI Viewer, a freeware mapping and database engine that allows viewing, printing, and simple queries of ESI data. (Both Macintosh and Windows installers are included in the download.)
  
• Shapefiles, data tables (.dbf), and an ArcView 3.x project.
  
• ArcExport files (.e00), with the relational and desktop data tables in ArcExport and text formats.

Downloads for ESIs that were generated using GIS (post-1993) include metadata in PDF format. Other metadata formats, as available, are included in a separate Metadata download.
