Overview of attributes

>The dataset may be downloaded in either ARC/INFO export format (.e00 files) or
>ARCView shapefile format.  A printable PDF version of the map is also available.
>The dataset consists of four coverages (ENNISGEO, ENNISFLT, ENNISSYM, and
>ENNISATT) and a  .tiff file containing the scanned USGS topographic basemap.  The
>coverages containing both arc and polygon or point entities, ENNISGEO/ENNISATT,
>have been divided into two separate sets of files in the ARCView shapefile
>format named ENNISGLN/ENNISALN and ENNISGPT/ENNISAPT for the line and point
>entities respectively.  All coverages contain the standard ARC/INFO items in
>addition to the items defined in more detail below.
