Bing Maps Web Control SDK retirement

Bing Maps Web Control SDK is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Web Control SDK until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Web Control SDK until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Web Control SDK will need to be updated to use Azure Maps Web SDK by the retirement date that applies to your Bing Maps for Enterprise account type. For detailed migration guidance, see Migrate from Bing Maps Web Control SDK and Migrate Bing Maps Enterprise applications to Azure Maps with GitHub Copilot.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

Module Name: Microsoft.Maps.SpatialMath

In some applications it may be necessary to perform complex spatial calculations, such as the distance between two locations, or intersection area of two polygons. The Spatial Math module provides several commonly required spatial calculations.

The Spatial Math module has three core parts:

  • Common Spatial Calculations: This part consists of a set of commonly used spatial calculations, such as the ability to calculate distances between locations, or perform unit conversions. These calculations are exposed as static methods on the Microsoft.Maps.SpatialMath namespace.
  • Geometry Calculations: This part consists of a set of complex geometric functions which can be used to perform binary operations against shapes (union, intersect, differences...), generate convex and concave hulls, and create Voronoi diagrams. These static methods are exposed through the Microsoft.Maps.SpatialMath.Geometry namespace.
  • Tile Math: This part provides a set of methods that perform spatial calculations based on the Tile pyramid used by Bing Maps as defined here. This is often useful when creating custom data visualizations. These static methods are exposed through the Microsoft.Maps.SpatialMath.Tile namespace.

In most calculations the distance or area unit parameters are optional. The default distance units used is meters, and the default area units is square meters.
