Remarks

The following example shows how to use the CalculateArea method to compute a map shape area:

C#

double areaByPoints = GeoUtils.CalculateArea(new List<GeoPoint> {
    new GeoPoint(41, -109),
    new GeoPoint(41, -102),
    new GeoPoint(37, -102),
    new GeoPoint(37, -109)
});

VB.NET

Dim areaByPoints As Double = GeoUtils.CalculateArea(New List(Of GeoPoint) From {
    New GeoPoint(41, -109),
    New GeoPoint(41, -102),
    New GeoPoint(37, -102),
    New GeoPoint(37, -109)
})
