W3c Geolocation API (Paperback)

High Quality Content by WIKIPEDIA articles! The W3C Geolocation API is an effort by the W3C to standardize an interface to retrieve the geographical location information for a client-side device. It defines a set of objects, ECMAScript standard compliant, that executing in the client application give the client's device location through the consulting of location information servers, which are transparent for the API. The most common sources of location information are IP address, Wi-Fi and Bluetooth MAC address, RFID, Wi-Fi connection location, or device GPS and GSM/CDMA cell IDs. The location is returned with a given accuracy depending on the best location information source available.
