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 /pub/open-file-reports/ofr-97-0052.

Green U.S. Geological Survey Box 25046, Mail Stop 905 Denver, CO 80225 ggreen@usgs.gov (303) 236-5390 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.

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.
