Hey
I'm using arc map for the first time to make a school assignment. For this I need to do the following, but I don't know how. I hope someone can help me.
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’
2. Do the same for the viewpoints (‘viewpointsBest’), with a maximum distance of 5000 meter in this case ‘Fviewpoints’.
3. add these two costs to your original pristine friction layer. 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’. Display your friction map (‘mapFrictionT’) with on top the four viewpoints and two settlements.
Step 1 and 2 succeeded, but I don't know how I need to do the 3the step. I think I will need raster calculator, but then the layers that lay beside the buffer doesn't get counted.
What schould I do?
With kind regards
Alyllyra
