Hi,
you might find the Shareware TOPAZ from Gabrecht and Martz helpful to
delineate subbasins. The output is in ascii format and no big trouble
to import that into a GIS. Another option might be the r.watershed
comand in GRASS.

Hi everyone
I am a graduate student at the university of arizona, I want to use DEMON
algorithm to delineate subbasin, the software I am using is Arc/Info. But
so far, this algorithm has not been combined with arc/Info. I want to use
this method by GRASS, and then change the result fime to Arc/Info format,
I just know a little about GRASS. would you like give me some suggestion
and answer the following questions:
1. is this idear pratical? i.e. is there the function to delineate
subbasin by DEMON algorithm in GRASS?
2. how to change Arc/info data format into GRASS format
3. how to use this algorithm
hope to receive your early reply
thanks

Hi Nicola
thanks for your advice. I know tapes have no the function to delineate
subbasin, but just calculate areas. I am trying to use r.watershed now.
