I'm still having troubles generating watersheds.

I would like to generate Watershed Areas in a 2 x3 km. DTM (1.6m. grid). The area i relatively flat: From 50m. to 110 m. in height.

I started the generation with a Stream Cell Count of 5000 and a Depression Fill Depth of 0.7 m. Today (2½ day after start) the process still hav'nt completed.(GM is stil trying to fill depressions).

This is realy bad - a GIS program like GeoMedia Grid can complete this Fill-operation in 15 minutes.

I'm using GM build nov11 2010 23:46:05

    We are aware that the depression filling operation needs re-done to avoid taking so long. I would suggest pressing Cancel to stop the depression filling which should allow you to just continue with the operation with whatever depressions have been filled so far.

    Let me know if I can be of further assistance.

    Thanks,
