questions

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

I don't know the DEMON algorithm. But I would say you're on the right track. If GRASS doesn't include the algorithm you want, you can include it! Just a Simple Matter of Programming--you could do it in C, or C++, or even PERL. Writing a new module for GRASS is not difficult.

I am a bit puzzled by your third question though. If you've already decided to use DEMON, why are you asking how to use it? Sorry if that's an obvious question; I'm a mathematician, not a hydrologist.
