GIS Data
- 3 minutes to read
GIS services allow you to receive information related to map locations. For example, you can obtain coordinates of a location by its name or create a route between two or more waypoints. The Map Control ships with a set of data providers that allow you to connect to GIS services and visualize data on the map. This topic lists available providers and explains how to use them.
Tip
The Map Control allows you to use Measurement UI and API to measure distances and areas on the map. For more information, see: Measurements.
The Map Control also ships with an API that allow you to measure geometric values based on geographical coordinates. You can use this information to develop custom map measurement instruments. Refer to the following help topic for more information: Geo

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:
- Azure
Map Data Provider - Azure
Search Data Provider - Azure
Route Data Provider - Azure
Geocode Data Provider - Azure
Traffic Incident Data Provider - Azure
Route Isochrone Data Provider
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.
