Hi All
I'm wanting to use a DEM/DTM to automatically map the watershed/catchment
area upstream of a known point.
After a bit of reading, this appears to be a not-so-simple task but
suggestions are to use the "Upslope Area" algorithm.
In my case, the program fails to finish running, and the message window
shows the following error:
SAGA Version: 7.8.2 (64 bit)
Error: tool needs graphical user interface [Upslope Area]
C:\Users\Tony\Documents>exit
Questions:
* Does anybody know what that error means?
* Is there another tool/method that is preferable to use?
Cheers
Tony
