Snow Leopard introduces a new slice to the Apple Core Framework, CoreLocation. As the name suggests, this new set of developer tools allows the operating system to find your approximate location. Although the iPhone has a similar framework that allows it to triangulate its location using cell towers, this is the first time this technology had been implemented in a computer operating system.
The new feature utilizes the Mac’s built-in networking hardware to find its location using IP data and is most likely based on the same Geolocation technology added in the latest version of Mozilla Firefox.
iPhoto 09′s Places feature has utilized GPS meta data to catalog photos by the location in which they where shot but this is the first time an Apple product other than the iPhone has been able to determine it’s own location without GPS support.
Snow Leopard uses CoreLocation to determine the computer’s current time zone. It will be interesting to see how developers uses this feature to enhance their own applications.
