[GRASS-user] Horton's streams order - has it sense?

[Jarek Jasiewicz]

Hi list!

I've just thinked how to create horton stream order based on my module 
strahler module and accumulation file. Hortons stream order differs 
sligty form strahler order, see for example here fig. 1 page 78 
http://iahs.info/hsj/134/134008.pdf

Because I have some tests results from some of you (many thanks for your 
courage) i'm about to finish module, modify code to meet grass 
requiments and officialy anouce it on grass-dev, but If I will add 
horton stream order it  will may take a bit more time.

So I have 2 question  about that (horton):

Did you think taht horton stream order has already sense (it is almost 
not in use)

Does any body know any program (commercial or not) which calculate 
horton's stream order

Thanks for ansvers
Jarek
