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.
--------------------------------------------------------------------------------
ENNISGEO: Polygon coverage containing all contacts and known or approximated
fault lines along with unit label points.
PAT Item Definitions:
UNIT_SYM is a character item defining the geologic unit represented by each
polygon using the unit abreviations defined in the accompanying pamphlet
(Proterozoic = !, Cambrian = _, Pennsylvanian = &, and Triassic = @)
SHADE_SYM is an integer item defining the cartographic color of each polygon
from the shadeset ctr269.shd
