This example demonstrates how to receive elevation data from the Bing Map Service.

Important

On May 21, 2024, Microsoft announced that Bing Maps for Enterprise and its API will be discontinued. Azure Maps will be a single unified enterprise mapping platform available from Microsoft.

To obtain and display map data from Azure Maps, we implemented the following providers:

For information on how to migrate your app from Bing Maps to Azure Maps, see the following help topic: DevExpress Map Control for WPF: Migrate from Bing Maps to Azure Maps.

If you already have a Bing Maps for Enterprise license, you can keep using the current API. You must transition to the new API by June 30, 2025 (for free/basic licenses) or June 30, 2028 (for enterprise licenses). New licenses will no longer be available after June 30, 2025. Bing Maps will not work with our map controls without a license after that date.

To do this, request the required elevation information using the BingElevationDataProvider.RequestPointsElevations method.
