Hi,
I'm working with a polyline stream network (National Hydrography Dataset/NHD) and points (barriers) along stream network. I'm trying to generate two outputs;
1. A path-distance matrix showing the shortest-path distance between a one point (barrier) and all other points (barriers) in the network. The output should look like the following
| Barrier | A | B | C | D |
| A | 0 | 10 | 15 | 20 |
| B | 10 | 0 | 5 | 10 |
| C | 15 | 5 | 0 | 5 |
| D | 20 | 10 | 5 | 0 |
where A:D are points (barriers), and numbers in the cells are total stream segment lengths between them.
2. A binary matrix for each path that shows which barriers lie along the path. The output should look like the following
| Source | Destination | A | B | C | D |
| A | B | 1 | 1 | 0 | 0 |
| A | C | 1 | 1 | 1 | 0 |
| A | D | 1 | 1 | 1 | 1 |
where Source is the starting point (barrier), Destination is the ending point (barrier), and numbers in the cells indicate where the point identified on the column lies on the path (1 = true, 0 = false).
Is anyone familiar with this type of network/path analysis and knows a workflow that can calculate these outputs using ArcHydro or other tools? I've been working in ArcGIS Pro, but have access to ArcMap 10.6 as well. Thanks!
