I have created a least cost path raster with three paths which I have then converted to three separate polylines. Everything works fine up to this point, but I would like to get the average slope and the absolute distance of each path. When I run Add Surface Information on my polyline data using the same surface I created the least cost path with, the resulting data is incorrect. The length of each polyline doesn't make any sense and my max slope for all three is 1000. The only correct data is the min and max elevation. Any suggestions are appreciated.
