How to: Specify a Map Projection

This example demonstrates how to specify the map projection that is used to display geographical data for a Map Control.

To configure a map projection, specify the GeoMapCoordinateSystem.Projection property of the GeoMapCoordinateSystem object. Assign it to the MapControl.CoordinateSystem property.

One of the following predefined map projections can be used.
