Region 8 GIS Data
You can download ARC files from our data warehouse (click on "E00"). The elevation and hillshaded relief are grids which have been "tar´d" but are not "e00"export files.  All of the data files are in Unix "gzip´d" Arc/Info 8.01 format. If you do not have the GZIP program, you can download it from www.shareware.com. Exit EPA disclaimer

For a detailed description of each data set click on "META".

NOTE: If your browser strips the ".gz" extension from the file, you will need to first rename it (<filename>.e00.gz or <filename>.tar.gz) and then "gunzip"it before importingor "un-tar"ingit.
