How to Read Location-Allocation Result

abdinafan — Tue, 17 Jun 2025 10:34:03 GMT

I want to know the distance between a demand point and the facility it allocated to, where can I see it?

Is it the DistanceToNetworkInMeters column in Demand Points attribute table? If it isn't, what does the value in there mean?

...or is it located in Total_Length column in Lines attribute table?

It's the Total_Length column in the Lines sublayer. (Because your travel mode is using an impedance attribute called Length). Here is the documentation for the Location-Allocation layer's schema: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/location-allocation-analysis-layer.htm

I see, thank you for your help!

But I'm still a little bit curious, what does the values in DistanceToNetworkInMeters column really mean?

DistanceToNetworkInMeters is the distance in meters between the point's geographic location and the position where it was located on the network. Here's some documentation explaining how points are located on the network: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/locating-analysis-inputs.htm
