Note

Bing Maps SDK for Android and iOS retirement

Bing Maps SDK for Android and iOS is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps SDK for Android and iOS until June 30th, 2025. Enterprise account customers can continue to use Bing Maps SDK for Android and iOS until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps SDK for Android and iOS 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.

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.

    TERRAIN,
    ELLIPSOID,
    GEOID,
    SURFACE
}

iOS

typedef NS_ENUM(NSInteger, MSMapAltitudeReferenceSystem)
{
    MSMapAltitudeReferenceSystemUnspecified = 0,
    MSMapAltitudeReferenceSystemTerrain = 1,
    MSMapAltitudeReferenceSystemEllipsoid = 2,
    MSMapAltitudeReferenceSystemGeoid = 3,
    MSMapAltitudeReferenceSystemSurface = 4
}
