I´m trying to map green corridors between different stands of hardwood, using Spatial Analyst Cost path tool. I think my cost distance and backlink raster are OK, but the cost path output normally gives a default message, saying in the Results that its empty. In the map view, all that exists are a few raster cells, on and around the input feature/raster data, sometimes in a gradient from green (good, low costs) in the north and red (high costs) in the south. Attached some pictures (upper: cost distance, middle: backlink, lower (cost path) to show what it looks like. This specific cost path result was however different, but still useless.
Anyone got solution for this?
