Note
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.
Heat maps, also known as density maps, are a type of overlay on a map used to represent the density of data using different colors. Heat maps are often used to show the data “hot spots” on a map. Heat maps are useful when you have a lot of data you want to look at on the map. If you were to display tens of thousands of pushpins on the map you will likely find that the performance of the map degrades and due to the number of pushpins majority, if not all of the map is covered, thus making it unusable. Rendering the data as a heat map has a lot better performance and helps make better sense of the density of the data while still being able to see and use the map.
