This routine is used to convert files in UNGenerate FORMAT to AVS format. UNGenerate files are produced by ARCINFO.
The UNG format is described below, see AVS format at READ/AVS.
ung2avs/avs_file_out/ung_file_in ung2av/avs_file_out/ung_file_in/[constant]/ & [xy, xz, yx, zx, yz, zy]
avs_file_out is the name of the AVS file to write
ung_file_in is the name of the UNG file to read
constant (default 0.) is the value to assign to z or the second axis indicated by axis options.
xy xz yx zx yz zy (default xy) detirmines axis values to write.
ung2avs/avs_file_out/ung_file_in
converts ung_file_in to avs_file_out with a constant default z value of 0.0
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
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
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.
1 x y x y x y ... END n x y x y x y END END
1 x y x y x y ... END n x y x y x y END END
