Hi! Could you please describe the process you used to combine the slopes with the streets? I'm working in a similar problem. I have the streets on a shapefile and the DEM of the region I need. I extracted the slope with the Slope tool and now I'd like to add that feature to my streets. Could you give me some advice?
For some reason it seems like the analysis is ignoring several streets in the analysis, thus shaping the polygons completely wrong. I've added a screenshot of the areas in question.
