    Firefox 3.5 does geolocation!

    Since early beta release of Firefox 3.1 there is experimental support for the experimental W3C Geolocation API.

    Now Doug Turner, one of the engineers who is behind the Geolocation support in Firefox, wrote a nice background story geolocation in Firefox 3.5 (hacks.mozilla.org). A very interesting read, and it turns out that geolocation is not only for mobile devices, but also available in regular Firefox versions, using wifi or IP address mapping.

    Using Firefox 3.5 or another location aware browser? Give it a try by clicking the button below, a map with your current location will be loaded…


    • Firefox 3.5b4 has an annoying bug (#490046) which lets you get your location only once per run.
    • Privacy is an issue, Firefox asks for permission by showing a notification bar on top of the screen. Click “Tell them” to proceed…

      Click "tell Them"...

    Map your location…

    What the script does…

    // call native geolocation API:
    // callback initializes a google map with the geo data:
    function callback(position) {
        var point = new GLatLng(position.coords.latitude, 

    Google provides a similar Geolocation API implementation through Gears.

    Got another browser where the API works? Please leave a comment!

      Update: indeed, the bug has been fixed in Firefox 3.5b99 – but some requests return a very unaccurate estimate, while others are perfect within only a few meters error.
      I guess in some cases Wifi is used, while in other cases generic Geo IP tables are used (e.g. if the Wifi lookup times out?).

      exactly. if a wifi position is found, that is the location that is shared with the website. if no wifi position is found, a location based on IP is shared.

      Keep in mind, all of this is optional — we don’t share anything until you click “share location” in the notification bar.

      Hope that helps!

      Works fine in the iPhone 3G mobile Safari (OS 3.0) browser, too.

        Cool, thanks!

        It doesn’t work out of the box on Android’s Webkit browser on the G1, need Google’s interface for that apparently.

    Google Geo Day 1 

    Google Geo Day, part 1

    Today the google geoday is held in Amsterdam Expo XXI

    The morning programme consisted of three speeches, most about google maps and google earth, focused towards developers who want to create mashups based on the maps API.

    A bunch of quick notes, some in Dutch (with the Dutch speakers mostly)

    (More …)
