OD Cost Matrix , Actual Route

MuhammadRamzan — Thu, 30 Jul 2020 23:33:38 GMT

I have made a Multimodal network analysis consisting of Maritime_Routes, World_Railroads, and World_roads as a mode of transportation.

I have applied the OD cost matrix and that works fine. I have to find out how many countries the route between the two cities is passing.

I have applied the OD cost matrix, calculates the distance and draw a straight line, rather than the ACTUAL ROUTE.

Thanks

Although the OD Cost Matrix tool shows straight lines connecting origins and destinations, the it calculates the network distance or travel time and reports those values in the output table. The straight lines are intended only for visualization, like a spider diagram.

If you need to use the output of a network analysis to determine which countries the route goes through, you cannot use the OD Cost Matrix tool. OD Cost Matrix only reports the travel time or distance and not the actual route.

You should instead use either the Route solver or the Closest Facility solver, depending on the way your problem is set up.

Can I apply the Route solver or the Closest Facility solver on the same Network data set? or if I have to set up a new network data set.

Yes, all of the Network Analyst solvers can work with the same network dataset.

I have tried but Closest Facility solver is not working. I need the distance from each origin to eash the destination.

Did you get an error message? An incorrect result? If you give me some details, I might be able to help.

No error message.

I need the distance(and actual shapefile) from each origin to the destination city. whereas in only pairs origin city with only one destination city. whereas I need to pair each origin city with each destination city.

You can set the number of facilities to find to some number >= the number of cities you have. Then you will get a route from each city to each other city.

How please

Re: OD Cost Matrix , Actual Route

MuhammadRamzan — Fri, 31 Jul 2020 19:37:12 GMT

where I can find or set this option.

Re: OD Cost Matrix , Actual Route

MelindaMorang — Fri, 31 Jul 2020 19:58:39 GMT

The option is on the Closest Facility ribbon.

I have 2341 cities. so I will set this number to 2341. Right?

I am getting this message

"Warning: The output geometry for "Location 3 - Location 1" in "Routes" has no M values because the maximum M value is larger than the largest M value that can be supported by the M domain."

MelindaMorang — Fri, 31 Jul 2020 20:48:39 GMT

Yes

Re: OD Cost Matrix , Actual Route

If you don't need M values, you can ignore this message. M values are used primarily for linear referencing when you need to know the distance along a line that a point falls.

Hi thanks

Is it possible to do the computation in Enterprise Geodatabase with ArcGIS Pro? As I have a large number of cities and it is taking to long.

What would be the process for that?

thanks

Yes, you can put your network dataset in your Enterprise Geodatabase, then set the network data source to point to that network dataset. However, I don't think that would make the analysis any faster.

Can you please refer me to any tutorial on this. thanks

Hi Melinda Morang

Hi, is the network model tool available in ArcGIS online version?

Thanks

Can you clarify what you mean by "network model tool"?
