[GRASS-user] RE: Hidrological network (ALT SHN)

Hi Andr, You mention that you have streams of different 'order', does that mean you have a table connected with a column containing a value for each bit of stream (e.g. the river and tributaries are a combination of vector lines, and each line between one stream junction and the next has a 'stream

Hi all, yes,yesYES thank you for your inputs :-) it was a simple case of me not having a table with the info in to start with, so once i remedied that with v.to.db (hello old friend, where have you been hiding?) reports and map queries were a breeze, as well as easy calculations directly on the ta

Thank you for your suggestions. It seems I will be having a hard time!! @Jarek - The vector has a good topology (I tested the topology using the layer to run a simple nearest path analysis and it worked, so I assume it's ok) I checked the attribute table and it has hundreds of objects and only two
