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
