Remarks
  • Universal Windows 10 AppAndroid MapDisplayPosition uses Google's geolocation service (or Bing Map for Universal Windows 10 App). The positions define from the description of a location depend on the quantity and on the precision of the information supplied in this description. If the same description correspond to several locations, the geolocation service will return the most suitable correspondences.
  • iPhone/iPad The cartography service used differs according to the version of the mobile device or tablet:
    • before iOS 6, the service used was Google's geolocation service.
    • after iOS 6, the service used was Apple's geolocation service.
  • iPhone/iPad We advise you to use the syntax 2 "Displaying a geographical position with check procedure".
  • The zoom level of the map is not modified when changing position.
  • To center the map on a specific position without performing the animation, you have the ability to assign a geoPosition variable to the Value property of a Map control.
  • Android To retrieve the list of addresses corresponding to the description of a place or a geographic location, use geoGetAddress.
  • Universal Windows 10 AppAndroidiPhone/iPad To find out the position currently displayed in the center of the Map control, use MapGetPosition.
  • Versions 21 and later
    Universal Windows 10 App The Map control is using the Bing Map service.
    Caution: The use of the Map control is subject to specific terms and conditions. A Bing key must be used (MapLicenseBing). Check the Bing license before deploying your applications.
