##Usage

Run from commandline

The output file will be written to a file next to the input file and its name will end in "_Cropped.asc"

    java -jar ESRI_DEM_CROPPER dem_file xmin xmax ymin ymax
    

	dem_file = input file of the dem elevation map 
	
	xmin = new lowest x coordinate must be between 1 and xxmax - 1
	xmax = new highest x coordinate must be between xmin +1 and NCOLS (in the file header)

	ymin = new lowest y coordinate must be between 1 and yxmax - 1
	ymax = new highest y coordinate must be between ymin +1 and NROWS (in the file header)
