GSMAP System 9 by Gary I. Selner and Richard B. Taylor; USGS Open-File
Report 93-0511.
NOTE: Minimal user documentation is included with this package. A printed user manual for the software, also labelled Open-File Report 93-511, is available for purchase from the USGS Books and Open-File Reports Section.
GSMAP (download all files in this directory to get the complete package) and related support programs including GSMEDIT, GSMUTIL,
GSMPBLD and GSMPBS have been developed to assist geologists and
illustrators in compilation and publication drafting of geologic maps
and illustrations. These programs attempt to facilitate geologic map
compilation and drafting in the way that digital word processing
facilitates composition and editing of text. As a set of practical
graphics programs, they enable digital compilation of graphical
elements, ease the process of modification in response to second
thoughts, editorial comments, and scale changes, and lead from initial
compilation to publication without redigitizing or redrafting. These programs are oriented for use by geologists and other scientists, not for computer
specialists. Programming skills are not required.
GSMGIS by Gary I. Selner, Gregory N. Green, and J. D. Hoffman, USGS Open-File Report 95-0570.
GSMGIS (self-extracting archive, 156 kb) is a program to import and/or export data between GSMAP and ARC/INFO, GRASS, IDRISI, EarthVision, GIV, Rockware STEREO, and MAPINFO. The program executes on IBM-PC compatible microcomputers using the MS-DOS operating system, version 2.0 or higher. The microcomputer must have at least 640K RAM and, as a matter of practicality, a fixed disk drive. A math co-processor is recommended. A text editing program capable of producing ASCII files is also required. (Note: this software is also included in the GSMCAD package.)
HPGLUTIL by Van S. Williams and Gary I. Selner, USGS Open-File Report 94-0284.
HPGLUTIL (download all files in this directory to get the complete package) reads Hewlett-Packard Graphics Language (HPGL) plotter command files and
transmits the commands to various types of output devices. It
will optionally rescale the drawing and transform the
coordinates. A drawing may be registered to a basemap mounted in
the plotter by using a digitizing sight to identify three
registration points marking the upper left, lower left, and lower
right corners of the drawing. An HPGL file must be prepared that
plots those three points first using exactly the same parameters
as the main plot file. The program will also change the size of
the plot without registration, for example, a D-size plot may be
reproduced on a page-size laser-jet. Pen color, width, and gray
tone can be set for output to some raster devices.
Potential-Field Geophysical Software for the PC, version 2.2, by Jeffrey D. Phillips, USGS Open-File Report 97-0725.
This report
describes DOS-based geophysical software available as
downloadable files. This software can be used for the geographic
projection, gridding, image display, contour display, filtering,
and interpretation of potential-field geophysical data. The
software consists of DOS executables, help files, test data files,
and source code, and is available in three downloadable, DOS self-
extracting files from
ftp://ftpmusette.cr.usgs.gov/pub/pf/.
This report supercedes Open-file report 92-0018.
Seismic Trace Plotting Program for Macintosh (self-extracting
archive, 536 kb), version 2.2; USGS Open-File Report 92-226, by John Miller.
The file Readme.documentation contains the version 2.0 documentation and user's
guide and file Readme.too contains documentation for the version 2.2 update.
Geologic and topographic map patterns and textures for use in Adobe Illustrator, developed in the Central, Eastern, and Western Publications Groups of the Geologic Division of the U.S. Geological Survey. This collection consists of 550 patterns and variations of patterns grouped into 20 files.
