GIS cataloging capabilities are used to document every DEM created for EDEN. Each contains metadata that includes information on the intended use, date of production, modifications from previous DEM versions, and spatial characteristics. A separate metadata file that meets Federal Geographic Data Committee spatial metadata standards is associated with each release DEM version (such as EDEN_EM_JAN07). This open file report documents the approach used to create release EDEN DEMs. Future DEM releases will reference this file for those interested in the approach used to generate them. If EDEN DEM production methods change significantly from those documented here (e.g., with the use of satellite or airborne remote sensed data for DEM interpolation), a new open file report will be published to document the revised approach. Release DEMs are freely distributed through the South Florida Information Access website (http://sofia.usgs.gov/eden/models/groundelevmod.php).
