                       Files on this Disk

CA-RASS.EXE  Self-extracts the files CA-RAS-B.DBF and CA-RAS-C.DBF which
     will require 1.6 Mgb of disk space.

CA-PLUTO.EXE  Self-extracts the files CA-PLU-D.DBF, CA-PLU-E.DBF,
     CA-PLU-F.DBF, CA-PLU-G.DBF, and CA-PLU-H.DBF which will require
     1.7 Mgb of disk space.

CA-MRDS.EXE  Self-extracts the file CA-MRDS.DBF requiring 38 Mgb of disk
     space.

CA-MIL.EXE   Self-extracts the file CA-MILS.DBF requiring 3 Mgb of disk
     space.

     A compression program was run on each of the four executable files listed
above.  This was done to enable distribution of all the data on two floppy
diskettes.  To access the archived files, simply copy the desired FILENAME.EXE
to your hard drive.  After copying the file to your hard drive, type the
FILENAME.EXE and press the Enter key. The file will decompress automatically.
     
     The first two letters of the archived filenames designate the state
followed by a dash and three or four letters indicating the database from which
the files originated.  The decompressed filenames also designate the state in
the first two letters, followed by three or four letters to identify the
database.  RASS and PLUTO database filenames include another dash followed by
a letter indicating the source from which the samples originated.  This sample
source information is explained in the file OF96-004.TXT.  All of the
decompressed files are in dBase (.DBF) format.  This format was used due to the
widespread availibility of many spreadsheet and database software programs
capable of importing dBase formatted files.

Disclaimers:
          
     The databases, identified as RASS, PLUTO, MRDS, and MILS, have been
approved for release and publication by the Director of the USGS.  Although
these databases have been subjected to rigorous review and are 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.
     
     Although the program LHA.COM ((c)Yoshizaki,1988-91) was used by the
USGS to archive these files, no warranty, expressed or implied, is made by the
USGS as to the accuracy and operation of the program and related program
material, nor shall the fact of distribution constitute any such warranty, and
no responsibility is assumed by the USGS in connection therewith.
