CTG2AVDS

This directory contains the files and directories that implement 
the example program, "CTG2AVDS.exe" which converts USGS 1:250,000 
Scale Land Use and Land Cover (LULC) Composite Theme Grid (CTG) 
data into AVDS color files. The source code, contained in the file, 
"ctg2avds.c", uses the AVDS Terrain Library (ATL) for this conversion.

USAGE:
	CTG2AVDS ctg_filename Rot TransX TransY SizeX SizeY

	where: 	ctg_filename - name of a LULC CTG file to be converted.
		Rot - angle to rotate the ouput color map in degrees
		TransX, TransY - amount to move the ouput color map in degrees
		SizeX, SizeY - size of the ouput color map relative to 
			       the original size, i.e. 0.99

OUTPUT:
	CTG2AVDS outputs intermediate files containing colors
        suitable for further processing with ATL functions.
	The names of these files have the form:
		XXX_XXX.c32 where the X's are numbers.
