Hello. IF YOU DON'T HAVE A UNIX ENVIRONMENT, THEN YOU PROBABLY WANT TO FTP THE ASCII DATA FROM ANOTHER MACHINE CALLED alum.wr.usgs.gov THE DATA CAN BE OBTAINED USING FTP ANONYMOUS IN THE DIRECTORY ~ftp/pub/map/ascii THE DATA SETS IN THIS DIRECTORY ARE WRITTEN AS REAL NUMBERS IN BINARY FILES. THEY CAN ONLY BE READ ON UNIX ENVIRONMENTS. The programs in this directory will output latitude and longitude geographic and fault data in an ASCII file corresponding to a rectangular region. NOTE: THIS PROGRAM DOES NOT PERFORM ANY PLOTTING. YOU WILL HAVE TO PROVIDE YOUR OWN SOFTWARE TO PLOT THE DATA PROVIDED BY THIS PROGRAM. The data files (ie., the *.bin) have been collected from various people who have digitized these maps for their own personnel research efforts. Please note that I cannot guarantee that all data points are accurate. You will need approximately 10.5 MBytes of storage to hold all the source and data files. The program, called "sift", is interactive, and prompts for the rectangle, the map scale, and output file name. The input scale factor is used to decimate the data so that data is output with appropriate resolution. The following coverages are available: California state outline California major Quat. faults from Jennings (1975) (hand digitized) California quaternary faults from Jennings (1992) ===> The 1992 Jennings fault data is copyrighted by the California Div. of Mines and Geology For access to these data, please contact David Wagner Div. of Mines and Geol. 801 K Street, MS 14-33 Sacramento, CA 95814-3532 916-324-7380 California major lakes and reservoirs California minor lakes and reservoirs Yellowstone faults, boundaries, lakes, calderas Snake River Plain outline Hawaii outline, geographic features U.S. state boundaries World map World tectonic plate boundaries Coalinga, CA anticline Mammoth Lakes, CA faults Mammoth Lakes, CA roads Mammoth Lakes & Mono-Inyo, CA geography Darrel Herds fault map of Morgan Hill Jon Mattis 1985 map of the Banning fault region Alquist-Priola flts in SF Bay region Sites of active creep in SF Bay region Major highways in SF Bay region John Sims Parkfield fault map Cenozoic anticlinal fold axes in southern CA Physiographic provinces of western U.S. Fault maps of Nevada The user can choose from a menu those regions of interest. In particular, there is a data base of the digitized fault map from the Jennings 1992 Fault Map of California published by the state. Unfortunately, CDMG has a copyright on this information and requires permission for redistribution of this information (See above address). A subset of this file, which was digitized by hand from the 1975 version of the Jennings map, is in the main menu as "cf". This output is easily editable. However, it is out-of-date and incomplete. The .bin files are binary format created by a SUN Sparcstation. If you have copied these files via FTP, you needed to use the "binary" option during the mget. If you don't have a Unix environment, then please contact me at the address below, and I'll uncompress the ASCII files that can be converted into the proper .bin format within your own environment. The Makefile will build the fortran program. However, before you make it, change line 30 in the begining of 'sift.f' to reflect the pathname where the ".bin" files will reside. Three different output formats are supported: Qplot: 6 coordinate pairs/record, decimal degrees, + west longitude, fortran format (6(f6.4,f7.4)), pen lift=(0.0, 0.0) Ascii dump: 1 coordinate pair/record, decimal degrees, - west longitude, fortran format (2(f10.5, 5x)), pen lift=(-999.0, -999.0) MapInfo (.MIF & .MID interchange format) Descriptive tags are output beyond column 80 for the Qplot and Ascii dump formats so that you can edit the output file if need be. If you have questions, suggestions, or bugs to report, you can send me E-mail at oppen@alum.wr.usgs.gov or call me @ 415-329-4792. If you have any digitized files to contribute, I'd be more than happy to enter them into this low-brow database. Good luck, David Oppenheimer
