Can anyone help on this query - I've loaded our rivers as a vector data
set, but the users want to determine the length of river between two
points. This is the length including all the bends, not just the 'as the
crow flys' one.Is there any GRASS function that can do this ?
There's always v.report, but it's not really interactive and has some
problems with category files that are not in the right format. And it
involves labelling all your rivers differently if you want to get the
information per river. Probably d.measure will be the easiest for your
users, but it will not be exact.
