How to convert coordinates in UWP Maps

Transform latitude and longitude value to pixel value and vice-versa

SfMap offers two utility methods to transform the pixel values to longitude and latitude values and vice-versa. These methods are used for both ShapeFileLayer and ImageryLayer.

• LatitudeLongitudeToPoint(double latitude, double longitude) - Converts the latitude and longitude values to a screen point. Here, pass the parameters as latitude and longitude values, from which you can get the screen points x and y.
• GetLatLonFromPoint(Point point) - Converts the screen point to longitude and latitude values. Here, pass the parameters as screen points x and y, from which you can get the longitude (Point.X) and latitude (Point.Y) values.

C#

Point pixelPoint = layer.GeopointToViewPoint(21.00, 78.00);
Point longitudeLatitude = layer.GetLatLonFromPoint(pixelPoint);
mapAnnotations.Latitude = longitudeLatitude.Y;
mapAnnotations.Longitude = longitudeLatitude.X;
