I am currently working on a project at work trying to find the river miles in respect to the location of over 3000 sample data points along a stream. I have two questions:
I am thinking of dividing the river route into 0.025 mi segments and by using joining method using spatial analysis by location and adding a offset value, I would be able to determine the river mile and join it to the sample points' attribute. Would this method work or is there a better way of finding the river miles of the sample locations? I know that I could also using Euclidean Allocation to do this, but I think the dynamic segmentation method would calculate a more accurate measurement of the river miles.
My second question is that I already figure out how to perform the dynamic segmentation on the river route feature, but the problem is that the starting point of measurement should start downstream, not upstream. Is there a way to change the starting point of the dynamic segmentation?
If you need any clarification on my problems, do not hesitate to ask. Thank you everyone for your help. I really appreciate it.
