For this I need to do the following, but I don't know how. I hope someone can help me.</P><P></P><P>1. Create a cost raster for the settlements, by means of Euclidian distance (max 10 000 meter) application to ‘settlements’ and inverting the distance to a cost (1/’distanceSettlements’*3 000 000), in order to get highest values closest to the settlements  ‘Fsettlements’</P><P>2.

Be aware: you have to make sure the area outside your viewpoint and settlement buffers retains the old values, which two tools can you use for this?  ‘frictionT’.
