The Digital Geologic Map of Wyoming in ARC/INFO Format

                        by

    Gregory N. Green and Patricia H. Drouillard

	This database, identified as OFR-94-0425, The Digital Geologic 
Map of Wyoming in ARC/INFO Format, has been approved for release and 
publication by the Director of the USGS.  Although this database has 
been subjected to rigorous review and is substantially complete, the 
USGS reserves the right to revise the data pursuant to further analysis 
and review.  Furthermore, it is released on condition that neither the 
USGS nor the United States Government may be held liable for any damages 
resulting from its authorized or unauthorized use.

	The database can be downloaded via 'anonymous ftp' from a USGS 
system named greenwood.cr.usgs.gov (136.177.48.5).  The files are 
located in a directory named /pub/open-file-reports/ofr-94-0425.

	This geologic map was prepared as part of a study of digital
methods and techniques as applied to complex geologic maps.  The
geologic map was digitized from the original scribe sheets used to
prepare the published Geologic Map of Wyoming (Love and Christiansen,
1985).  Consequently, the digital version is at 1:500,000 scale using 
the Lambert Conformal Conic map projection parameters of the State base
map.  Stable base contact prints of the scribe sheets were scanned on
a Tektronix 4991 digital scanner.  The scanner automatically converts 
the scanned image to an ASCII vector format.  These vectors were
transferred to a VAX minicomputer, where they were then loaded into
ARC/INFO.  Each vector and polygon was given attributes derived from
the original 1985 geologic map.

     This database was developed on a MicroVAX computer system using VMS 
5.4-3 and ARC/INFO 5.0.2 software.  The lineset and shadeset files are 
coded for a Calcomp electrostatic plotter.  

	The database was reviewed at the University of Wyoming, Wyoming 
Water Resources Center.  The review was cross-checked at the USGS in 
Denver.

	The authors wish to thank Dave Love and Ann Coe Christiansen for 
providing access to the original Geologic Map of Wyoming scribe sheets 
and negatives.  For the digital review, we also thank Pat Stamile of the 
USGS and Chris Arneson and Laisan Serebryakov of the University of 
Wyoming Water Resources Center.

	In order use this database, ARC/INFO software and hardware and FTP 
transfer software to copy the database to the ARC/INFO platform are 
required.  To install the database, run LOAD.AML.

WATER, ROADS, CONTOURS, AND TOWNS:

	Published geologic maps are prepared using a USGS topographic base 
map that contains the hydrology, hypsography, and political features.  
Because this digital version of the Geologic Map of Wyoming started with 
the original geologic scribe sheets, these features were not present.  
Only those water bodies that were required to close polygons were added 
by hand.  The digital hydrology is not complete or as accurate as the 
original USGS 1:500,000 topographic base.  A few water bodies were added 
for visual effect.  No roads, contours, or towns were present on the 
geologic scribe sheets and none were added to this digital version. 

LINESETS, SHADESETS, AND FONTS:

	The plot program WYOMING.AML uses two linesets, CARTO.LIN and 
CCA.LIN.  As the WYOMING.AML runs, black lines are produced from the 
INFO item BW which calls the ARC/INFO CARTO.LIN line set; to generate 
color lines the INFO item CCA calls the electrostatic 1024 color line 
set file, included as lineset CCALIN.E00.

	To produce polygons three shadesets are used.  Color polygons are 
produced from the INFO item CCA which calls the electrostatic 1024 color 
shadeset file, included as shadeset CCASHD.E00.  To generate polygon 
patterns the INFO items DOT and PLT call the shadeset file DOT, included 
as DOTSHD.E00 and the shadeset file PLOTTER.E00.  PLOTTER.SHD is the 
default ARC/INFO shade set. 

	The text font for the four special geologic symbols is included as 
font FNT003.FNT.  The ASCII code for @ has been redefined to the symbol 
for Triassic, the ASCII code for & has been redefined to the symbol for 
Pennsylvanian, the ASCII code for _ has been redefined to the symbol for 
Cambrian, and the ASCII code for ! has been redefined to the symbol for 
Proterozoic and Late Archean.


CONTACTS, DECORATIONS, DIKES, BORDER, and EXPLANATION coverages:

	The Digital Wyoming Geologic Map is made of four spatial datasets. 
The map coverages are (1) contacts and faults, (2) decorations,(3) 
dikes, and (4) the border-title.  The attributed vector portion of the 
contact coverage is CONTACT.AAT. The attributed closed polygons of the 
contact coverage is CONTACT.PAT. DECO.AAT is an attributed vector 
graphic overlay of the decoration coverage. This dataset contains the 
teeth of thrust faults, shear zones, bars and balls, impact structure, 
diatremes, and ARC/INFO annotation. The polygon portion of the 
decoration coverage, DECO.PAT, is an attributed closed polygon graphic 
overlay.  In order to fill the teeth and the balls with black paint, 
these had to be topologically structured.  DIKES.AAT is the attributed 
vector file of the single line outcrops.  Dikes at a scale of 1:500,000 
are best represented by a thin single line and consequently have no 
area. The DIKES.PAT file is present but blank. The BORDER coverage is 
the scale bars with ARC/INFO annotation.

The Explanation sheets replicate the original explanations and 
references, within the limits of ARC/INFO.
