Measure Network from Outlet¶
Summary¶
Compute a new measure attribute
as the distance of each link to the network outlet.
This algorithm also sets the M coordinate of input geometries. When there are anabranches or parallel branches, diffluence nodes are attributed the maximum distance to outlet, so as to minimize overlap in M coordinate.
Input must be a preprocessed, downslope directed stream network, with single part geometries.
