For those interested in the geology of the map area that do not use an ARC/INFO-compatible (Environmental Systems Research Institute, www.esri.com) Geographic Information System (GIS), we have provided two sets of plot files containing images of much of the information in the database. There is a plot file image in Adobe Acrobat PDF (<http://www.adobe.com/>) format (see Plot file Package sections below).
Those who have computer capability can access the plot file packages in any of the three ways described below (see the section Obtaining the Digital Database and Plot file Packages). However, the plot file packages do require zip utilities to access the plot files. Therefore, additional software, available free on the Internet, may be required to use the plot files (see Zip files section).
Those without computer capability can obtain plots from an outside vendor (see section Obtaining plots from an outside vendor).
Note: filenames used in this report are based on combinations of the Open-File Report number, followed by an underscore, followed by the number of the package, followed by an alphabetic character denoting the part of that package, followed by a ".", and a three or four digit file extension. For example, for a text file of the metadata part of the documentation package (package number 1) in Open-File Report OF99_999 (a fictitious report number) would have a file name of of099_999_1a.txt
Documentation Package The Documentation Package includes descriptions of this report, including instructions on how to get the report, data formats and content. It consists of 3 parts, a text description (this file), FGDC compliant metadata describing the report, and a revision list that lists any revisions made to this report. The documentation package contains the following:
of06-1165_1a.txt a text file of the report text (this file) of06-1165_1a.pdf a PDF file of the report text (this file) of06-1165_1b.txt a text file of the geologic description pamphlet of06-1165_1b.pdf a PDF file of the geologic description pamphlet of06-1165_1c.txt a text file of FGDC compliant metadata for this report of06-1165_1d.html a HTML file of FGDC compliant metadata for this report of06-1165_1e.html a HTML 'FAQ' file of FGDC compliant metadata for this report
Digital Database Package
The database package includes geologic map database files for the map area. The digital maps, or coverages, along with their associated database directory have been converted to uncompressed ARC/INFO export files for distribution. ARC export files promote ease of data handling, and are usable by some Geographic Information Systems in addition to ARC/INFO (see below for a discussion of working with export files). Additionally, ARC export files are files that contain both the spatial and associated database information, so that it is possible to read and interpret the files and write simple code to convert the files to a format more convenient to the user, should no such code be available off-the-shelf. The ARC export files and associated ARC/INFO coverages, and directories, as well as the additional digital material included in the database, are described below: of06-1165_2a.e00 Faults, depositional contacts, and rock units in the quadrangle of06-1165_2b.dbf A DBF table of field observations The database package (of05-1165_3.zip) also includes the following files: of06-1165_1b.txt a text file of FGDC compliant metadata for this Report import.aml an ARC/INFO Arc Macro Language file for importing the above coverage
Converting ARC export files ARC export files are converted to ARC coverages using the ARC command IMPORT with the option COVER. To ease conversion and maintain naming conventions, we have included an ASCII text file in ARC Macro Language that will convert all of the export files in the database into coverages and create the associated INFO directory. With the Workspace set to the directory containing the Arc Export files, from the ARC command line type:
Arc: &run import.aml
ARC export files can also be read by some other Geographic Information Systems. Please consult your GIS documentation to see if you can use ARC export files and the procedure to import them. Note: consult the metadata or the Database Specifics section of this Report for details of the format and content of the digital database
Plotfile Package For those interested in the geology of the map area whom don't use an ARC/INFO compatible GIS system, we have included a separate data package of printable maps created from the database. Because this release is primarily a digital database, the plot files (and plots derived from) have not been edited to conform to U.S. Geological Survey standards. Small units have not been labeled with leaders and in some instances map features or annotation overlap. The map image is 29 by 64 inches and requires a large plotter to produce paper copies at the intended scale. of06-1165_3a.eps A PostScript format file containing an image of the geologic map, at a scale of 1:100,000. of06-1165_3a.pdf A PDF format file containing an image of the geologic map, at a scale of 1:100,000.
This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
This database 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 digital data can be obtained in any of three ways: a. From the USGS Web Pages. b. Anonymous ftp over the Internet c. Sending a CDR with request
