<div>As a side note:</div>
<div> </div>
<div>We use the following line in the .map files under our grayscale imagery layers:</div>
<div>PROCESSING "COLOR_MATCH_THRESHOLD=3"</div>
<div> </div>
<div>This reduces the number of colors used up by the imagery and makes space in the color table for other uses.</div>
