Getting Lat/Long from Camera point

BrianBulla — Wed, 27 Jul 2022 19:03:03 GMT

Hi,

I'm trying to get the the Lat/Long coordinates of the active MapView Camera point. I can get the Camera point in X/Y, but having trouble converting. This is how I am doing it:

MapPoint cameraPoint = MapPointBuilder.CreateMapPoint(Camera.X, Camera.Y); var projectedPoint = GeometryEngine.Instance.Project(cameraPoint, SpatialReferences.WGS84) as MapPoint;

Any guidance is appreciated.

When you create the MapPoint you have to include the Camera's spatial reference. This worked for me, but it's Pro 3.0:

MapPoint cameraPoint = MapPointBuilderEx.CreateMapPoint(cameraBefore.X, cameraBefore.Y, cameraBefore.SpatialReference); var projectedPoint = GeometryEngine.Instance.Project(cameraPoint, SpatialReferences.WGS84) as MapPoint; MessageBox.Show($@"projected [x,y]: {projectedPoint.X}, {projectedPoint.Y}");

Thanks Wolf. Here is my 2.9 code that is now working.

MapPoint cameraPoint = MapPointBuilder.CreateMapPoint(Camera.X, Camera.Y, Camera.SpatialReference); var projectedPoint = GeometryEngine.Instance.Project(cameraPoint, SpatialReferences.WGS84) as MapPoint;
