Because I tried it without google, just using this: navigator.geolocation.getCurrentPosition(callback) Gives you the same precise coordinates, in all browsers I've tried.

Clear your cache and run tshark when you send the request. See what data it sends. I do not understand how it could nail your house with just your IP. Do you have a cellular connection built into your laptop? What ISP? Maybe your ISP shares data with google?

  I do not understand how it could nail your house with just your IP If you've submitted contact information (mailing address, billing address) on a site that partners with MaxMind, then you may have provided them your exact address and IP. I'm sure Google must use this as one of their geolocation sources. http://www.maxmind.com/app/ip-location-explained http://www.maxmind.com/app/ip-location-explained

    Nope, maxmind detects my location incorrectly (25 miles off).

      Keep in mind that this would be one of many data points Google pieces together to get the most accurate location. MaxMind is 1000 feet off for me (likely because the data was incomplete because of privacy scrubbing), but spot on with Google Maps (down to my location within my condo complex). Some other data points that would give Google this information are Google Maps on my Android phone. With explicit permission to read and report my coarse (network-based) and fine (GPS) location, it would be able to read any WiFi access point in range of my phone and link that with my exact GPS location and report that to Google. I leave this enabled at all times for Google Latitude. I would imagine that anyone with a smartphone and Google Maps who came near enough to your house could have reported your access point and GPS location to Google. Even if you don't have WiFi, if the neighbors on both sides of you do, they could extrapolate that to your house in the middle.

I'm on cable, and my results both in google maps and with this call are highly general. (City Level / accuracy: 24000) We've had this cable account for years and many different people have used it so it's interesting that neither the street view car nor MaxMind have pinpointed it.
