Thank you for your work, Markus, it's wonderful :)<br><br>Best,<br><br>Margherita<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Hi all,<br>
<br>
in grass-addons is a new module for clean stream network extraction from<br>
flow accumulation. It can extract streams from accumulation maps<br>
generated with any method (D8, FD8, D-Inf, DEMON, etc) and any software,<br>
granted that exactly the same elevation map is provided that was used to<br>
calculate flow accumulation. In case of r.terraflow, that would be the<br>
flooded (filled) output elevation map, not the elevation map used as<br>
input for r.terraflow. For e.g. TAS flow accumulation as input, it must<br>
be the elevation map used within TAS to calculate flow accumulation.<br>
<br>
r.stream.extract output is available as raster and vector with unique<br>
stream IDs. The vector is a complete network with stream segments and<br>
points for stream heads, confluences and outlets. The raster output can<br>
be used as input for the r.stream.* modules of Jarek, also in grass-addons.<br>
<br>
Regards,<br>
