Help for GTASTERFIX

PURPOSE:
When asterlog changes the HDF ASTER files into VICAR files, the
label is not compatible to be used with VDEV programs such as
gtwarp and gtcopy.  "gtasterfix" changes and updates the labels
so that the image can be input into VDEV programs.

EXECUTION:

Example

gtasterfix A  -- where A is the input file.
                               
OPERATION:

Opens the VICAR file.
Acquires the MODELTIEPOINTTAG labels and their values.
Performs least squares fitting on 3 corner points.
Deletes the MODELTIEPOINTTAG labels.
Adds MODELTRANSFORMATIONTAG into the labels.
Closes the VICAR file.

TIMING: 

Look at OPERATION documentation.  As fast as the machine
can perform those operations.
