At page 235 from book "OPEN SOURCE GIS - A GRASS GIS Approach" 3rd edition:
"Natural neighbor interpolation is implemented in addon module r.surf.nnbathy. It uses “nn” – a natural neighbor interpolation library and allows the user to define breaklines such as stream lines or ridges as 2D lines without the need to define their elevation" http://www.sieczka.org/prog/grass/r.surf.nnbathy.html I searched for more information on how to implement 2D stream breaklines in a DEM creation but I haven't found anything relevant. Can someone help me? Thank you Luís Ferreira _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
