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.

This is a static class that provides a compression algorithm to encodes/decodes a collection of Location objects into a string and back. This algorithm is used for generating a compressed collection of locations for use with the Bing Maps REST Elevation Service. This algorithm is also used for decoding the compressed coordinates returned by the GeoData API. Note that the GeoDataAPIManager automatically converts the compressed polygon rings in the Primatives property of the response into a Polygon object for you. In addition to the REST Elevation service and the GeoData API this class can be also be used to encode/decode your own data. The encoded data is much smaller than most other formats such as GeoJSON or Well Known Text which is useful if passing data between a client application and a server. The algorithm for decoding the string is documented here, and encoding is documented phere.
