find nearest facility

MauricioRamirez1 — Fri, 18 Sep 2020 01:51:27 GMT

When we receive an incident request, we need to find the nearest facility to that address. By the time we go to search, we have already converted the address to a set of coordinates. I have a layer with my facilities. What's the best way to find the nearest facility using the runtime SDK for QT.

You can use ClosestFacilityTask.

Here is a sample in QML - arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_QMLSamples/Routing/ClosestFacility at master · Esri/arcgis-runtime-samples-…

And here is the C++ version - arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples/Routing/ClosestFacility at master · Esri/arcgis-runtime-samples-…

In our samples, we use mouse click to get the coordinates, but in your case, you can just create a Point object from the coordinates you have instead.

I notice you create points manually. In my case the points are in a layer on the ArcGIS server. Is there a way to iterate through that?

Yup, we show that type of workflow here :

QML - arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_QMLSamples/Routing/FindClosestFacilityToMultipleIncidentsService at master …

C++ - arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples/Routing/FindClosestFacilityToMultipleIncidentsService at master …
