Yes, I found this problems too for using v.strahler.. <br>so we tried to solve with r.strahler.. but we still have some problems for low values of (r.wateshed) threshold.. <br>but maybe Jarek has a better way with this new approach to the problem..<br>
just "no dependencies" sounds good..<br>so we wait for good news!<br><br>Annalisa<br><br><div class="gmail_quote">2009/7/28 Jarek Jasiewicz <span dir="ltr"><<a href="mailto:jarekj@amu.edu.pl">jarekj@amu.edu.pl</a>></span><br>

I have compiled and used Jarek's stream order script and the results<br>
look to be satisfactory- good job!. <br>

You use windows as I remember, isn't it It is very important for me if program also work on windows. Please send me aslo feeback about time of analysis and size of maps<div class="im"><br>

I am having a hard time creating<br>
vectors from this raster representation. r.thin -> r.to.vect creates<br>
lots of erroneous squares that I believe are there as an artifact of<br>
the larger stream networks. <br>

It is problem that no streams are marked as 0 (for now, it will be fixed to null). For now try to<br>
convert 0 to null with mapcalc formula: neworder=if(order=0,null(),order) and try again.<div class="im"><br>

The lower order (smaller) streams look<br>
fine, but when you start getting to the higher order streams +5 I<br>
think the r.thin algorithm may have problems delineating a stream. <br>

Is<br>
there a way around this? I would be happy with a line that ran<br>
through the middle of the stream for now. Some trick converting to<br>
points and then to lines? Or something along those lines. Is there a<br>
way to connect centroids? I have made an area map of the streams<br>
raster- can I connect the areas together? Thanks for any help.<br>
thanks,<br>
<br>

I just work on another module which will be convert stream netowork to correct vector stream network (in most cases r.to.vect do not it well) i thing it is metter of next week.<div><div></div><div class="h5"><br>
