<div>Dear all,</div>
<div> </div>
<div>I have a DEM, a drainage and a Cover mapa, and I need to</div>
<div>estimate - for ANY pixel of my drainage - what is the </div>
<div>amount of my cover classes that "contribute" (or are upstream) </div>
<div>of that pixel.</div>
<div> </div>
<div>Any help are VERY welcome.</div>
<div> </div>
<div>Cheers</div>
