[GRASS-user] HydroFlow: Stream order soleley based on shape files/vectors

2013-06-18 Thread Johannes Radinger
Hi, I found following interesting Brasilian program called HydroFlow: http://www.fgel.uerj.br/labgis/hydroflow/en/downloads_ingles.html This tools calculates the Stream order (e.g. Strahler, Shreve) based on a shapefile input of the river network and a shapefile that defines the border

Hi Johannes! I tried that program like a year or more ago .. It worked well once you know howto do it .. It delivers it's one shapelib with it and can only do changes on shapefiles .. So it must be probably changed to a neutral dataset provider .. I was about to adapt it for QGIS but did not

1) Concerning the flow direction / network direction So far what I can understand from the html-manual, the only two input data is the map with the river network and a line or polygon file the defines the catchement. The flow direction within the network is then defined by the outflow point which

Hi, I used the software some time ago and it worked nicely. And as Johannes explained, the only data needed is the river network and the basin boundary. I'll try to translate the algorithm behind the software but I'm a bit confused by it so I could be doing a worse job then a google
