How to: Load a Vector Cartesian Map

• Apr 15, 2018

To load a vector Cartesian map, do the following.

1. Crete a ShapefileDataAdapter object.
2. Set its CoordinateSystemDataAdapterBase.SourceCoordinateSystem property to a CartesianSourceCoordinateSystem object.
3. Specify its ShapefileDataAdapter.FileUri property.
4. Assign this object to the VectorLayer.Data property.
