layCountries.Style.Fill = new SolidBrush(Color.Green);
layCountries.Style.Outline = System.Drawing.Pens.Black;
layCountries.Style.EnableOutline = true;

SharpMap.Geometries.Point point = new SharpMap.Geometries.Point(50, 12);
SharpMap.Data.Providers.GeometryProvider provider = new SharpMap.Data.Providers.GeometryProvider(point);
SharpMap.Layers.VectorLayer layer = new SharpMap.Layers.VectorLayer("point", provider);
