Positioning

The user's location is one of the key pieces of information in building a Web map application. The Nokia Maps API supports the use of W3C browser positioning, making it easy for an application to use positioning information.

Precision depends on the positioning technology and ranges from rough IP Positioning (only supported in a few browsers such as Mozilla Firefox), cell positioning (usually available on tablets and notebooks) up to very precise WiFi detection (all WiFi-enabled modern browsers, among them mobile browsers). In addition, The API supports GPS or A-GPS on tablets and smart phones, which delivers very accurate positioning.

Visual presentation of positioning data on the map includes proximity rendering.
