Description of the issue:  
I follow this how to Guide ([How to Integrate the VPS Coverage API with Lightship Maps | Niantic Lightship](https://lightship.dev/docs/beta/maps/unity/how-to/integrate_vps)), however, I am stuck on Converting the LocationInfo “mapCenter” to LatLng. The proposed method in the HowToGuide “ToArdkLatLng()” does not seem to exist according to error message. I also could not find said method in the LatLng namespace. Can you help me out?

‘LatLng’ does not contain a definition for ‘ToArdkLatLng’ and no accessible method accepting a first argument of type ‘LatLng’ could be found (are you missing a using directive or an assembly reference?)

I ran into some other issues before, so I had to add other namespaces, here are my current ones in the script:  
Niantic.Lightship.Maps  
Niantic.ARDK.VPSCoverage  
Niantic.ARDK.Extensions  
Niantic.ARDK  
ArdkLatLng = Niantic.ARDK.LocationService.LatLng  
MapsLatLng = Niantic.Lightship.Maps.Core.Coordinates.LatLng  
Niantic.Lightship.Maps.MapLayers.Components  
Niantic.ARDK:LocationService  
System  
System.Collections  
System.Collections.Generic  
UnityEngine

EDIT: The script at the end of the How-To Guide is correct. It is only in the step by step guide, that the code is wrong.

Fixed it, here’s how I resolved it:

public void RequestAreasAroundMapCenter(){  
var mapCenter = \_mapView.MapCenter;  
var mapCenterARDK = ConvertArdkLatLng(mapCenter);  
\_coverageClient.RequestCoverageAreas(mapCenterARDK, \_queryRadius, OnAreasResult);  
}

public void OnAreasResult(CoverageAreasResult areaResult){  
…

```
foreach(var area in areaResult.Areas){
            var areaID = area.LocalizationTargetIdentifiers[0];
            var areaShapeMaps = ConvertMapsLatLng(area.Shape)
           _areaBorder.DrawLoop(areaShapeMaps, areaID)

```

}
