    Geotargeting in browser - how?


    I'm a little concerned by the way websites are identifying me - I want to know, first of all - how does geolocation work? How is your location calculated? The only thing that came to *my* mind when I thought about it is for the server to ping the client and use the time, but that's HIGHLY unreliable, and anyway, it would give a radius, a circle of location, not ONE particular one.
    Number two, why does HTML 5 have features for geolocation? There have been websites that ask for my location, but since others can get it seemingly perfectly well without me agreeing, what was the point?

    Thanks.

    Actually the site asks the browser and the browser ask you for permission. If you don't want to be geolocated turn it off in your browser.

    If your device has GPS it is used, sometimes RF triangulation and other times IP address location data can be used. Some sites use it for the data they are serving.

    Nope, there have definitely been sites that get my location without asking me anything.....

    What is "RF triangulation" and "IP address location data"? Is the latter the result of a WHOIS lookup or something?

    There is an IP addressed based database that can be used by servers - it only works for fixed locations and deals in generalities and may be outdated and is based on where the service provider is.

    Radio frequency triangulation. Location based on the length of time signals from multiple (at least three) cell towers take to reach a cell phone.

    Location data that the service provider may choose to make available to the browser.

    Where did it come from? Who made it? How do you use it?
