Subject: Creating a route on a network for fish locations in a river
Question
QUESTION: I have a years worth of fish locations and I would like to create a path on a network to each location in chronological order. My aim is to calculate the total distance traveled and distance traveled in each segment. I have created the network and my fish locations have a
date field to order the points. I have attempted to use network annalist but all I can get is the shortest path not the entire route.
Can you help?
ANSWER: I answered the same question before.
Brows past answers to find the question titled as "Network distance between between two points".

QUESTION: Network annalist will find the distance between 2 points on a network but I am trying to find the distance between 10-100 sequential points for 90 fish so calculating the distance between each sequential point is not that efficient. I did try to use network annalist for multiple points but it only gives the shortest route not the actual distance traveled. For instance, I had a fish swim from downstream to upstream and back network annalist will only draw the route one way. Do you have any suggestions for measuring each segment of a route consisting of three or more sequential points on a network?
Answer
There are two options that I suggest you to try:
1- Make a shape file of all the points.
When trying to find the best rout, select the shape file as event file
instead of clicking on individual points.
2- Before clicking "solve", check "return" (something like that)
This will solve the best rout for both directions. In addition, there is an option which gives you the detail of the traveling path.
Please let me know if that solves your problem.
