Re: [GRASS-user] accumulation map from directions map
Hello again, I am still searching a method to generate a flow accumulation map from a flow direction map. I got the direction map from an arcgis user. In arcgis the module FLOWACCUMULATION(FLOW_DIR) would do this, but I want to use an open source solution. If anyone could give me a hint, where I could find a tool like this (inside GRASS it does not seem to be possible), I would be very grateful.

Thanks, Jaroslaw for response, there shoud be no problem if you have oryginal DEM I know, but I do NOT have the DEM. Thats the problem.

Re: [GRASS-user] accumulation map from directions map
Hi Silvia, thank you very much. I will use h.tca from JGRASS to get the desired. Best, Achim Silvia Franceschi schrieb: Hi Achim, if you are trying to use an open source GIS for hydrological applications consider to take a look at JGrass. There are a lot of geomorphological modules. Best regards Silvia Hello again, I am still searching a method to generate a flow accumulation map from a flow direction map.

Ah, now I understand is there a way in GRASS to build an accumulation map from a directions map without a dem map? So: If you are on earth, you can get it here (mars/moon should be also available somewhere :-): http://grass.osgeo.org/wiki/Global_datasets - SRTM - ASTER GDEM especially http://grass.osgeo.org/wiki/ASTER_topography If you need to start from the accumulation map and no way to use a DEM, then I have no idea (but see the other comments) Hope this helps, Markus ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] accumulation map from directions map
Dear Markus, I follow Silvias suggestion and use h.tca in JGRASS. BTW: Isn't is possible to integrate the horton-tools into grass?
