00readme.txt -  DOS ASCII text file that describes the digital data for U.S. Geological Survey Open-File Report 02-393, 10/15/02, ksb

Bolm, K.S., Lewis, Tasha, Hirschberg, D.M., Pitts, G.S., and Dickinson, W.R., 2002, Spatial digital database for the geology of the San Pedro River basin in Cochise, Gila, Graham, Pima, and Pinal counties, Arizona: U.S. Geological Survey Open-File Report 02-393 digital database, version 1.0, 36 p., 1 digital map sheet, scale 1:125,000 (received Director's approval September 30, 2002).

This report describes the contents of a digital data set which consists of ArcInfo exchange-format and associated text files.  The page-sized, color version of the digital geologic map is included in the report.  An Adobe Acrobat PDF file for printing a paper copy of the map at a scale of 1:125,000 is also included.  The database is available via anonymous FTP from geopubs.wr.usgs.gov, in the directory pub/open-file/of02-393.

Requirements:  A networked computer system is required to copy the files 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 map file is stored in Adobe portable document file format (quib24k_map.pdf).  The digital data files are in UNIX ASCII format.

Explanation of digital data files:

The GIS for version 1.0 of the "Spatial digital database for the geology of the San Pedro River basin in Cochise, Gila, Graham, Pima, and Pinal counties, Arizona" is available as the compressed UNIX TAR file, quib24k.tar.Z, which includes the report text (of02-393.pdf) in an Adobe portable document format.

To set up the digital database in an UNIX environment, create a new workspace in Arc, change directories to the new workspace, and download the quib24k.tar.Z files to your new workspace.  Use the 'uncompress -v quib24k.tar.Z' to uncompress the file.  Use the command 'tar -xvf quib24k.tar' to extract the files from the TAR file.  And finally, to import the ArcInfo exchange-format files (*.e00) into your workspace, start ArcInfo on your workstation and enter '&run importfile.aml' at the Arc prompt.

Your working directory should contain the following files:

00readme.txt - this readme file in DOS ASCII text format
importfile.aml - ArcInfo program to import ArcInfo interchange-format files into the user's workspace
of02-393.pdf - report text in Adobe Acrobat PDF format

ArcInfo exchange-format files (*.e00) and metadata include:
quib24k.e00 - principal line and polygon geologic map GIS (contacts, structures, and map units) in UTM  projection
quib24kg.e00 - line and poly GIS (contacts, faults, folds, and map units) in a geographic reference system (latitude and longitude)
quib24kp.e00 - point GIS (structural data such as strike and dips, and fault attitudes) in UTM projection
quib24kpg.e00 - point GIS (structural data such as strike and dips, and fault attitudes) in  a geographic reference system (latitude and longitude)
quib24k.met - FGDC-compliant metadata file

Files in this package have been attributed to produce plots using the shade, line, and marker sets listed below.  These sets are included for the user's convenience.
