Overview

Using the Map control, you can load and depict any set of geographic visualization data (placemarks, polygons, images, textual descriptions, etc.) stored in the KML (Keyhole Markup Language) format. KML files have a tag-based structure with nested elements (similar to the XML standard).

Note

For more information, see the following link: KML Documentation.

One of the common usage scenarios for the KML format is to display vector data above an image tiles map. For instance, the image below shows a shape loaded from a KML file.

Load KML File Data

To load vector data from a KML file, do the following.

• Create a KmlFileDataAdapter object.
• Specify the path to a KML file using the FileDataAdapterBase.FileUri property.
• Assign the KmlFileDataAdapter to the VectorItemsLayer.Data property.
