Solved! Go to Solution.
I have looked into that. The problem is for every point I have 2 sets of coordinate points (that are not displayed) within the attribute table that I want that specific point to connect to. So I have my original point data, and then I used the near tool to get coordinates of the closest rail segment, and also road segment that I want to connect to. Those two sets of coordinates are not points yet because I do not know how to display multiple attribute columns of coordinates. I feel like that is pretty elementary but I cannot find a tool to do it.
Moral of the story is each point has two other sets of coordinates in its' attribute row and I want to connect that point to those two XY coordinates.

I have a question about this.
I'm doing something similar, but the difference is that I'm connecting airline flights across different time blocks (600-700, 700-800, etc)
I've already made Polylines for each time block, but I want to connect separate flight paths (ie, Dallas to Houston connects in Houston for a new flight path Houston to Amarillo, etc) but I don't know how to retain the time block and connect the Polylines into a single flight route for the entire day. Any suggestions?
Hi there,
Thanks so much for the in-depth response, it's really appreciated!
Essentially (in broader strokes):
- Create a working network of flights starting with the Linear Referencing Route tool using the Route_ID (which is really a line between Departure & Arrival)
- Use the Start Time (min) and the End Time (max) for each segment as the From-Measure and the To-Measure and set in units of Time
- Use the Create Route tool and designate Time as the field that will govern the sequence of the routes
- Modify the Environmental Settings of the Create Route tool so that "M" values are Fractional (instead of Integer)
- Once the Route is created, then each flight will have a corresponding Route_ID and Departure time and Arrival time associated to it as a measurement
NEXT (the 2nd feature layer) is an EVENT table derived from the Linear Referencing Route tool?
- I'm confused here about how to pull the arriving flight at any given time and match it to the correct departing flight? (Or. has this already been achieved by sequencing the segments based on Time during the Create Route step?)
You suggest:
"this should probably be a modeled derivative of the more detailed data and you should perform maintenance on the finest level of detail that makes sense."
- Can you give me an example of what I need to derive as the "Total Day" field if I were to connect the Flight IDs together using the Create Route tool? (Ex, Total Day = ??? units? what value? )
- FINALLY, once the Network is built and is functional, then I can move into the Routing problem and optimization territory...
But, I'm still a little unclear on the specifics I've listed above that are necessary to make the network functional.
Thank you SO much for your help, thus far. I appreciate any other insight you can impart.
Sincerely,
Holly G.
