BACKGROUND INFORMATION ON THIS PUBLICATION

This CD-ROM publication contains raw and interpreted data, maps, and other graphic displays linked to the geological history and characteristics of the Upper Cretaceous-age Sussex Sandstone of the House Creek oil field, Powder River Basin, Wyoming. Data were statistically analyzed and mapped in 2-D and 3-D, and included as ASCII-formatted, space-delimited data files. Files included on this CD-ROM can be retrieved for use in other applications, including graphics editing and display, mapping, and statistical programs. Graphics are stored as Graphics Interchange Format (GIF) and TARGA (TGA) images (see glossary for explanations of acronyms and words).

World Wide Web (WWW) network browsing software is required to integrate the graphics images and text located on this CD-ROM. While included HTML (Hypertext Markup Language) documents (in the "ssx_txt" directory) can be viewed with standard word-processing software, the interactive capabilities of Web browsing software link text, images, movies, and data. Numerous graphics software programs can view and edit individual GIF and TARGA files which are located in the "ssx_gif," "ssx_tga," and several other directories.

This CD-ROM was produced in accordance with both the ISO 9660 and Macintosh HFS standards. Contained data and text files can be read by platforms supporting either of those standards. Also required is a CD-ROM drive and associated software. Provided graphics and movies are designed for use under DOS/Windows on IBM or 100 percent compatible personal computers (PC's) and the Apple Macintosh family. The stand-alone EarthVision faces file is a 3-D model intended for use on Silicon Graphics Corporation IRIS workstations. This ssxporos.faces file displays porosity distribution and sand-ridge boundaries for the House Creek field. The ssxporos.demo.Z and evview.Z compressed files are located in the "IRIS" subdirectory; these files are intended primarily for archive, but they can be loaded onto an IRIS workstation to create a stand-alone EarthVision 3-D model.

All brand and product names are trademarks or registered trademarks of their respective companies. The ^tm notation is not appended to these product names, largely because the HTML superscript notation did not work with all World Wide Web (WWW) browsers. The authors primarily use Mosaic as the reference for accessing the information on this CD-ROM. The Mosaic programs located on this CD-ROM are software that are written and upgraded at the National Center for Supercomputer Applications (NCSA) at the University of Illinois in Urbana-Champaign. Included with computer programs located in the "software" directory are general directions to copy Mosaic and other applications for your platform. Other network browsing programs are available and have been used to view this publication.

Mosaic and associated software are available through anonymous FTP (file-transfer protocol) from NCSA. The ftp location is ftp.ncsa.uiuc.edu. Due to the number of people that use, and overload, the network, you may need to make several attempts to access and copy the files from NCSA. We recommend linking with the NCSA network early or late in the day. You are utilizing FTP on UNIX computers; remember that UNIX is case sensitive.

The file-naming convention on this publication is primarily eight dot three. This indicates the file has a maximum of eight characters to the left of and three to the right of the ".". An asterisk (*) is used in this publication as a symbol to match all characters. It commonly indicates a longer file name, for example Mosa*.hqx would access all .hqx files that start with Mosa and end with .hqx, such as Mosaic.hqx.

While this is dependent upon your system and software, stand-alone movies located in the "movie" directory can be opened by 1) starting your movie viewer and opening the movie file, 2) double-clicking on individual movie names or icons, or 3) accessing the movies with imbedded links in the HTML documents, which is the slowest option of the three. The *.MOV movies are designed to run on Macintosh and PC/Windows computers. The movies were created using the QuickTime and GraphicConverter software programs on a Macintosh IIsi. Our experiments with MPEG formatted movies produced lower quality images and are not included with this publication. File names displayed on each movie image are saved as separate GIF and (or) TARGA files; single 3-D images can also be displayed from the "3-D images and movies" subsections of the table of contents.

• Note: The price of this CD-ROM does not include costs of the software located on the disc. Please consider the usage requests of the software authors and companies. Instructions for how to use programs and where to contact the companies are in text files, generally associated with the software programs.

   Files located on this CD-ROM are accessed locally and linked by the WWW browsing software using the File command heading and Open File or Open Local subheadings (generally). For that reason, MacTCP software is not required to view the files. MacTCP v. 2.0.2 (or later) Apple software is needed to connect to a remote host (also known as cruising the Web). MacTCP now comes bundled with System 7.5. Your software needs may be different, depending upon the network browser software utilized.

2. Minimum of 4 MB RAM; 8 MB or greater is recommended

3. Should you load Mosaic or other WWW software on your hard disk, suggested minimum disk space is 3 MB.

4. This program requires a Macintosh with a 13" or larger color monitor and CD-ROM drive. The drive and software should support ISO 9660 or HFS standards.

5. QuickTime software was used to display the GIF movies and images located on this CD-ROM. QuickTime needs to be installed in the Extensions folder within your System folder. QuickTime will run on all Macs with 68020, 68030, 68040, or PowerPC processors (essentially everything but Mac Pluses, SE s, and PowerBook 100 s).

INSTALLING MOSAIC FOR PC/WINDOWS

1. Create a directory for NCSA Mosaic and copy into it the Microsoft Windows ZIP file that is specific for your Windows version.

2. Follow the procedures that are specified in the readme.txt text file located in "../software/pcwindow/mosaic." Note that the executable version of Mosaic for Windows95 (Win95x20.exe) includes a 32-bit driver. Installation of the executable for Windows3.1 and 3.2 (Win31x20.exe) requires incorporating 32-bit drivers; this software is available as Win32s with OLE v1.30a from NCSA. The NCSA program is also located in the "software" directory and is named w32sOLE.exe.

3. A program element can be inserted for Mosaic by choosing New under the File menu. Refer to your computer system documentation for the icon creation procedure. Mosaic.EXE is the executable file for Mosaic.

INSTALLING MOSAIC FOR MACINTOSH

1. Copy the compressed version of the NCSA Mosaic for Macintosh 2.0.1 software to your hard drive. Mosai68K.HQX is the compressed Mosaic file name for Macintoshes that have 68020, 68030, or 68040 processors (this excludes Power Macintoshes, Mac Pluses, SE s, and PowerBook 100 s). Mosai68K.HQX is located in "software/mac/mosaic/Mosai68K." Mosaic for Power Macintoshes is named MosaiPPC.HQX and is located in the "software/mac/mosaic/MosaiPPC" subdirectory. Decompressed versions of this software are also located in the subdirectories. Once you have copied the NCSA Mosaic .HQX file from this CD-ROM to your computer, open it using decompression software. One of these is StuffIt Expander software, which is located in the "/software/mac/stuffit" and "/software/pcwindow/stuffit" subdirectories on this CD-ROM.

2. Decompressing the .HQX and resulting .sit file creates the Mosaic executable program. Following decompression, the .SIT and .HQX files can be deleted as they are of no further use. Double clicking on the resulting file (name or icon) will start Mosaic. This 3-D tour is started by opening the homepage.htm file. This is accomplished by choosing "open file," "open local," or similar command under the "File" heading on the WWW browsing software.

INSTALLING MOSAIC FOR UNIX

1. First copy the compressed Mosaic binary file that is specific for your computer platform to your hard drive. These are located in "/software/unixzip/mosaic." Uncompress the downloaded Mosaic binary (an example for a Silicon Graphics Corporation, Indigo computer is: "uncompress Mosaic-indy.Z").

2. Create the binary executable using the "chmod" command (for example, type "chmod 755 Mosaic-indy" ).

3. Execute the resulting binary file, thereby opening Mosaic.

COMPUTER PROGRAMS LOCATED IN THE "MAC," "PCWINDOW," AND "UNIX" SUBDIRECTORIES OF THE "SOFTWARE" FOLDER
