CartesianMapCoordinateSystem Class

This class allows use of the Cartesian coordinate system for the Map Control.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v23.2.dll

NuGet Package: DevExpress.Wpf.Map

Declaration

C#

public class CartesianMapCoordinateSystem :
    MapCoordinateSystem

VB.NET

Public Class CartesianMapCoordinateSystem
    Inherits MapCoordinateSystem

Remarks

An object of the CartesianMapCoordinateSystem class can be assigned to the MapControl.CoordinateSystem property.

Example

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.

        }

        private void VectorLayer_DataLoaded(object sender, DataLoadedEventArgs e) {
            mapControl.ZoomToFitLayerItems();
        }
    }
