Catchment areas with friction surface

Question asked by martin.duffy73 on Nov 16, 2018

I am using ArcGIS desktop 10.4. I have a shapefile of 494 points. I also have a cost surface/friction surface raster. I want to create a polygon of 13.4 hectares around each point based on the friction surface. In other words I dont want a simple buffer around each point, The polygon should look irregular as it should follow the friction values.

I also want to produce another polygon with the same points and friction surface that will outline one hours walk from the point - I think I can do this in Grass but Im wondering if there is a good way to do in in ARC

Thanks in advance for any help
