The Digital Geologic Map of New Mexico in ARC/INFO Format

by Gregory N. Green and Glenn E. Jones

This database, identified as OF-97-52, The Digital Geologic Map of New

Mexico 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 the USGS.

The files are located on greenwood.cr.usgs.gov in a directory named

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 in GSMAP version 8 (Selner and Taylor, 1992) at Socorro, New
Mexico

by Orin Anderson and Glen Jones and published as the Geologic Map of New

Mexico 1:500,000 (Anderson and Jones, 1994) in GSMAP format. The vector
line

work and polygon point labels were converted to ARC/INFO format on a DOS

based PC with GSMARC (Green and Selner,1988). These data were
transferred

to a Data General UNIX system and loaded into ARC/INFO. Each vector and

polygon was given attributes derived from the original 1994 GSMAP
geologic

map. Both digital versions are at 1:500,000 scale using the Lambert
Conformal

Conic map projection parameters of the State base map.

This database was developed on a Data General computer system using

DG/UX Release 5.4R3.10 UNIX and ARC/INFO 7.0.3 software. The lineset and

shadeset files are coded for a HP 650C plotter.

The authors wish to thank Orin Anderson for providing access to the

Geologic Map of New Mexico GSMAP data sets. For the digital review, we
also

thank Nancy Shock and Pat Stamile of the USGS.

In order to 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 New Mexico started as a
geologic

map, these features were not present. Only those water bodies that were

required to close polygons were added. 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 GSMAP version of the geologic map and none were added to

this ARC/INFO version.

LINESETS, SHADESETS, AND FONTS:

The plot program NMMAP.AML uses one lineset, NMLIN.LIN. As the NMMAP

AML runs, the line color and width are set by the INFO item HP.

To produce polygons, NMMAP.AML uses the INFO item HP to panel fill based

on colors in the NMSHD.SHD shadeset.

The text font, FNT003.FNT, contains four special geologic symbols. 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.

Nmmap.aml, the geologic map sheet aml, will produce an ARC graphic .gra

of 47.9 by 52.1 inches. The resulting plot is to large for E size paper.
Try

the trick of plotting the map twice. Once in the conventinal manner and
once

after using the ARC command ROTATEPLOT twice. The results can be spliced

together.

CONTACTS, DIKES, INDEX and SOURCES coverages:

The Digital New Mexico Geologic Map is made of two spatial datasets. The

map coverages are (1) contacts, dikes and faults, and (2) the volcanic
vents.

The attributed vector portion of the contact coverage is NMMAP.AAT. The

attributed closed polygons of the contact coverage is NMMAP.PAT.
VENTS.PAT

is a point file of the isolated volcanic vents. At a scale of 1:500,000
these

vents are best represented by a marker symbol.

The Index and Sources coverages are graphic versions of our attempt to

present this traditional information within the limits of ARC/INFO.

Nmindex.aml, the index sheet aml, will produce an ARC graphic .gra of
25.9 by

32.7 inches. Sources.aml, the sources of data sheet aml, will produce an
ARC

graphic .gra of 22.7 by 35.4 inches.
