0readme.txt -- DOS ASCII file that describes the digital data for U.S. Geological Survey Map I-2593, 2/13/2002, pd Harrison, J.E., Whipple, J.W., Lidke, D.J., Kayser, H.Z., and Miller, R.J., 2001, Spatial digital database of selected data from the geologic map of the western part of the Cut Bank 1o x 2o quadrangle, northwestern Montana: U.S. Geological Survey, Geologic Investigations Series, Map I-2593, version 1.0, 31 p., 1 digital sheet, scale 1:250,000. Received Director's Approval January 2, 2002. URL = http://pubs.usgs.gov/imap/i2593/ This report describes the contents of a digital data set which consists of ArcInfo exchange-format files and associated macro programs. A page-sized, color version of the digital geologic map is included in the report. The data set also includes macro programs and complete plot files for creating a paper copy of the map at a scale of 1:250000. The data set is available on the World Wide Web at http://pubs.usgs.gov/imap/i2593/. Requirements: A networked computer system is required to copy the data set from the host computer across the Internet. A geographic information system (GIS) capable of importing ArcInfo exchange-format files is required for access to the digital files. The plot files are stored in Hewlett-Packard HPGL2 format (cb250k.hp), encapsulated PostScript format (cb250k.eps) and Adobe Acrobat portable document format (cb-map.pdf). The digital data files are in UNIX ASCII format. If you wish to run the cb250k.aml program: You will need to download the fonts of the "GeoAge" fontgroup and the "0content.txt" and/or the "0content_GeoAge.txt" files for details. Contact Richard Koch (rkoch@usgs.gov) if you need help. *************************************************** Explanation of digital data files: The GIS for the Cut Bank quadrangle is available as one UNIX compressed TAR file, i2593.tar.Z, which includes the report text (i2593.pdf) in an Adobe Acrobat Portable Document File (PDF) format. To download the GIS data files, create a new workspace in a UNIX working environment and copy the i2593.tar.Z file to your new workspace. Use the command 'uncompress -v i2593.tar.Z' to uncompress the file. Then use the command 'tar -xvf i2593.tar' to extract the files from the TAR file. And finally, to import the ArcInfo exchange-format files (*e00) into your workspace, open ArcInfo on your workstation and enter '&run importfile' at the Arc prompt. Your working directory should contain the following files: 00readme.txt - this file in UNIX ASCII format importfile.aml - ArcInfo program to import ArcInfo interchange-format files into the user's workspace. i2593.pdf - Report text in Adobe Acrobat Portable Document File (PDF) format. Primary ArcInfo exchange-format files (*.e00) and metadata (*met.txt) include: cb250k.e00 - principal line and polygon geologic map coverage cb250kmet.txt - metadata file Additional ArcInfo exchange-format (*.e00) and font files necessary to re-create the digital geologic map: cb_quad.e00 - map neatline fnt026.e00 - font 26 fnt037.e00 - font 37 fnt038.e00 - font 38 fnt039.e00 - font 39 fnt040.e00 - font 40 geoafa__.fon - GeoAge font geoafa__.pfb - GeoAge font geol_dia.lin.e00 - lineset wpgcmyk.shd.e00 - shadeset ArcInfo AML, graphics, key, and text files necessary to re-create the geologic map: cb250k.aml - program to create graphics file of the geologic map scale2a.aml - program to plot scale bar indx_cb.gra - index map graphic file usgslogo.gra - USGS visual identity cb-lin.key - lineset symbol values and descriptive text for explanation cb-pol.key - shadeset symbol values and descriptive text for geologic map units in the explanation geo.prj - a text file used to identify real-world (geographic) coordinates - for use in adding latitude and longitude notation around the margins of the map. tvm.prj - a text file to identify Transverse Mercator map projection - for use in adding latitude and longitude notation around the margins of the map. cb-crd.txt - text file listing map credits cb-dis.txt - text file for USGS disclaimer cb-prj.txt - text file listing map projection information cb-ref.txt - text file listing map references Plotter calibration file: cal.dat - the color calibration file used in the ArcInfo 'HPGL2' command to create plot files of the plates for plotting on the USGS HP650C in the Spokane Field Office. This file is a custom file for this particular plotter. Other plotters will require their own custom color calibration file.
