Hi,
for a GIS project I'm trying to get the LS-factor respectively the slope length out of a DEM.
I tried the following steps:
1. fill dem (hydrology/fill)
2. get flow direction (hydrology/flow direction)
3. get flow accumulation (hydrology/flow accumulation), but I'm not sure about the result. It looks wrong, most of the cells got the value 0.
what's the next step here, is this workflow even right ?
Input:
LIDAR DEM
Software:
ArcGIS 10.1 (Info)+ Hydrotools
Greetings,
Bernhard
