Introduction The Location API provides an easy way to retrieve data about geographic location while protecting user privacy. The Location API provides its functionality through a set of COM interfaces that represent objects. locationapi.h header is used by Location API

COM Interfaces ICivicAddressReport IDefaultLocation ILatLongReport ILocation ILocationEvents ILocationPower ILocationReport

ICivicAddressReport ICivicAddressReport represents a location report that contains information about: Street address City name Postal code Country/region

IDefaultLocation IDefaultLocation provides methods used to specify or retrieve the default location.

ILATLONGREport ILatLongReport represents a location report that contains information in the form of latitude and longitude.

ILocation ILocation provides methods used to manage location reports, event registration, and sensor permissions.

ILocationEvents ILocationEvents provides callback methods that you must implement if you want to receive event notifications. Methods: OnLocationChanged OnStatusChanged

ILocationPower ILocationPower is used by Windows Store app browsers in Windows 8 to notify the location platform that an app has been suspended (disconnect) and restored (connect). Methods: Connect() Disconnect()

ILocationReport ILocationReport is the parent interface for location reports. Methods: GetSensorID GetTimestamp GetValue

Windows.Device.Geolocation API Provides APIs for getting the current location or tracking the device's location over time.  The accuracy of the location information depends on the source. The latitude and longitude may vary within the following ranges: GPS : within approximately 10 meters Wi-Fi : between approximately 30 meters and 500 meters Cell towers : between approximately 300 meters and 3,000 meters IP address : between approximately 1,000 meters and 5,000 meters
