| Apr 13, 2016 at 21:12 | comment | added | carderne | Great, that worked! I'd looked into that before but somehow didn't figure it out properly. Can you make a proper reply so I can mark it as the solution? Thanks a lot! | |
| Apr 13, 2016 at 20:25 | comment | added | carderne | I tried again by converting the point to a raster, using Snap Pour Point, different cell sizes... No luck. EDIT: Missed your comment, I'll try that now. | |
| Apr 13, 2016 at 20:21 | comment | added | FelixIP | It means that your processing extent is wrong. Use environment settings and set it = flow direction raster, snap to flow direction, and cell size=fdir as well. I should of tell this from the shape of your 'watershed', straight lines is the sign to watch. Check this out gis.stackexchange.com/questions/157767/… | |

| Apr 13, 2016 at 19:34 | comment | added | FelixIP | FYI ' on the river' placement is not usually working. Use flow accumulation classified to place pour point | |
| Apr 13, 2016 at 19:29 | comment | added | FelixIP | Anything, e.g. dem or flow direction. It shows where stream running from source point | |
| Apr 13, 2016 at 18:55 | comment | added | carderne | Could you elaborate on that? I've never used cost paths before. What should I use for the Cost Distance raster? | |
| Apr 13, 2016 at 18:32 | comment | added | FelixIP | Place point in the upper part of the catchment. Use flow direction as backlink raster and see if costpath goes through place where you stuck | |
