如何将折线中的起点和终点转换为arcgis pro sdk中的WGS84

Question

我有一个如下所示的代码，坐标以米为单位，需要转换为WGS系统

    private async void ShowBalloonCallout(Geometry geometry)
    {
        
        if (geometry is Polyline polyline)
        {
            var startPoint = polyline.Points.FirstOrDefault();
            var endPoint = polyline.Points.LastOrDefault();
        }
    }

Answer 1

我确实喜欢下面的代码

public MapPoint ConvertToWGS84(MapPoint originalPoint)
 {
     var spatialReferenceWGS84 = SpatialReferenceBuilder.CreateSpatialReference(4326);
     MapPoint projectedPoint = (MapPoint)GeometryEngine.Instance.Project(originalPoint, spatialReferenceWGS84);
     return projectedPoint;
 }
