I have been to the following thread and used the equation given for calculating the RUSLE LS factor: http://forums.arcgis.com/threads/55694-Slope-Length?highlight=RUSLE. However, I am obtaining results in the 500's. I know this cannot possibly be right. I tried projecting the rasters into a USGS Albers Equal Area Conical but my results ended up being in the 50000's. I believe that it has something to do with how I am putting in the cell resolution. Does anyone know if that is my problem or how the equation given was derived so I can manipulate it for my watershed?
