OPTHILL Terrain Processor for CTSG Features
----------------------------------------------------------------------

Purpose:
--------
          Compute the optimum hill-shape exponent and length-scale
          parameters for a set of distance, height pairs which
          describe the hill profile from the crest to the base along
          one axis.  These parameters are then entered into the control
          file via the GUI, or by using an editor.


Demonstration:
--------------

          Prepare hill-shape exponent and length-scale parameters for
          the two axes of the terrain feature used to illustrate the
          use of OPTHILL in the Users Guide (Section 4.1.4).

   NAME        TYPE     SIZE(bytes)             DESCRIPTION
___________   _______  ____________     ____________________________

 OPTHILL.EXE  Program       522,836     Executable
 RUNOPT.BAT   Program         3,834     Batch file

 AXIS1.INP    Input             457     Control file for first axis
 AXIS2.INP    Input             457     Control file for second axis

 AXIS1.LST    Output          1,182     Results for first axis
 AXIS2.LST    Output          1,182     Results for second axis



Procedure:
----------

1.  Two applications of OPTHILL will be made, one for each axis.  Both
    are orchestrated by the batch file RUNOPT.BAT.  The data describing
    the feature profile along each axis are contained in the control
    file.

2.  Process the first axis by typing:

    runopt opthill.exe axis1.inp axis1.lst [return]

3.  The program reads the processing instructions from AXIS1.INP, and
    overwrites the axis1.lst file listed above.  If you wish to direct
    the output to a different file, replace "axis1.lst" with another
    filename that conforms to the "________.___" convention.

4.  Review the .LST file for the configuration used, and resulting 
    CTSG parameters.

5.  Repeat steps 2, 3, and 4 for the second axis.  The command is:

    runopt opthill.exe axis2.inp axis2.lst [return]
