U.S. GEOLOGICAL SURVEY OPEN FILE REPORT 94-255 The Southern Lake Michigan Coastal Erosion Study CD-ROM By C.F. Polloni1, C.L. Brown2, D.W. Folger1, D.S. Foster1, and A.L. Brill3 Display software by Russell A. Ambroziak4 Documentation by Christine A. Cook4 1U.S. Geological Survey, Woods Hole, MA 02543 2U.S. Forest Service, Jacksonville, OR 97530 3Duke University, Durham, NC 27708 4U.S. Geological Survey, Reston, VA 22092 GETTING STARTED This document, GETSTART.DOC, is designed as an introduction to this CD- ROM. The display software requires a VGA color monitor and a Super VGA graphics card with 640 by 480 pixels and 256 colors. You also need a mouse, and a math coprocessor is strongly recommended. Some new systems may find that they need the vesa graphics driver supplied with the graphics card. Using the vesa driver provides for higher resolution graphics. To view the CD-ROM material, place the disc into the disc drive. At the DOS prompt, type the drive letter followed by a colon and then press return. At the CD-ROM drive DOS prompt, type RUN followed by return. This mode of operation does not require any hard disk space but executes slower than installed programs and does not allow the user to save image files to disk. DOS users who wish to save image files to disk should make the CD-ROM drive the active drive; then type INSTALL. For starts after installation, type C:\SLMMAP. Non-DOS users should copy and convert map files from the other available graphics formats listed in the A_README.1ST file in the disc's root directory. After launch, DOS users see the following menu tree: MAIN MENU 1 - Introduction 2 - Overview 3 - User Information menu 0 - Return to previous menu 1 - Getting Started 2 - Disc Contents 3 - Documentation on Bathy 4 - Documentation on Klein 4 - Additional Information menu 0 - Return to Main Menu 1 - Acknowledgments 2 - Points of Contact 3 - Disclaimer 4 - References 6 - User Registration 5 - Authorship 6 - View Maps - Figures 1 thru 5 To exit to DOS, press To activate a menu option, either move the highlight bar over that option and press , or type the corresponding number. The display software was written by Russell A. Ambroziak and is part of the Geologic Information Visualization (GIV) package. The primary programs used are MAPPER and VIEWLBL. Option 6 Main Menu, View Maps - Figures 1 thru 5, calls the program MAPPER, which is mouse operated. Option 6, View Maps - Figures 1 thru 5, brings up the option to pick a figure for one of the maps for this study. After selecting a figure, press return or the left mouse button. If you see the error message, "Could not boot the board," then, either your video card is configured for a setting other than 640 by 480 by 256 colors or the installed card is not one we currently support. In the latter case, you will have to place one of the aforementioned cards into your computer, properly configure it, and try the disc again. While looking at the great lakes map, you will see a menu along the top of the screen. This digital map is fully interactive, and most of the functions of MAPPER will work directly off the CD-ROM. The function 'save map' will not work because a file cannot be written to the CD-ROM. In order to save a map, you will have to copy the file 'MAPPER.EXE' on to your hard disk and use the following command line: c:>mapper l:\giv where 'c:>' is your hard disk, and 'l:' is the CD-ROM drive letter. Alternatively you can go to the cd-rom drive and type 'install' and the install program will set up a directory called 'SLLMAP' on the drive of your choice and copy some *.bat files to the root directory of your system. The cd-rom drive is recorded and the menu program can be started at any time by typing 'SLMMAP'. The digital maps contained on this disc were created by MAPPER and related programs; MAPPER is not only a visualization tool, it is also a creation tool. Therefore, many of the functions in MAPPER are designed for creating a digital map as well as displaying it. For more information on how to use MAPPER, see the MAPPER tutorial. All the other menu options allow you to view documents about the disc, the data on the disc, acknowledgments, and so forth. The text files are ASCII files and can be printed using the DOS 'print' command or brought into a text editor. You are en- couraged to fill out the User Registration form found within the Additional Information menu. End of text; press the Escape key to continue.
