UNG2AVS

This rountine is used to convert files in UNGenerate FORMAT to AVS format.
UNGenerate files are produced by ARCINFO.

FORMAT:

ung2av/avs_file_out/ung_file_in/[constant]/ & [xy, xz, yx, zx, yz, zy]

default is:

ung2avs/avs_file_out/ung_file_in
     converts ung_file_in to avs_file_out with a constant default z value of 0.0

  or

ung2avs/avs_file_out/ung_file_in/7.0
converts ung_file_in to avs_file_out with a constant default z value of 7.0 in xy order

  or

ung2avs/avs_file_out/ung_file_in/15.0/xz
converts ung_file_in to avs_file_out with a constant y value of 15.0 in xz order
 

UNG file format:

The UNG format contains a file of xy values, in groups of sequentially numbered sets, of connected line segments, each ending with END. The format for connected lines that form polygons or that do not form polygons is very similar. To make sets of connected lines that are polygons the first xy pair for each set of lines must be on the same line as the set number. Closed polygons will be formed by connecting the last point of a point set to the first point of the  point set. The set number is on a line by itself for non-polygons. Spacing on a line must not contain tabs.

    FORMAT for connected lines that do not form polygons:

           1
             x   y
             x   y
             x   y
               ...
           END
           2
             x   Y
             x   y
            x   y

               ...
           END
               ...
           n
             x   y
             x   y
               ...
           END
           END

    FORMAT for polygons:

           1 x   y
             x   y
             x   y
               ...
           END
           2 x   y
             x   y
             x   y
               ...
           END
               ...
           n x   y
             x   y
               ...
           END
           END
