find nearest facility

[MauricioRamirez1]

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/arc... 

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

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 :

C++ - arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples/Routing/FindClosestFacilityToMultipleInciden...
