Working in ArcGIS.
I am looking for a way to find the distance of a point along a streams polyline. I read Finding distance of point along polyline? and it seems to be similar to what I need...the distance of something downstream.
I went ahead and clipped my stream lines to only downstream to avoid any confusion on my part. I also created start points of each stream polyline.
I tried to use the 'Locate Features Along Route'; I get the distance the point is from the line...not how far down it is from a starting point...
