Google Maps Mobile (My Location)
on: November 28, 2007, 21:46:34 PM
Thought this was pretty good.  Google maps mobile is now working out where you are by triangulating from phone masts.

Ideal for phones using google maps that havent got built in GPS.

PS: Not sure if the iPhone build has gone live yet (will check tomorrow) but for people whove done a jailbreak you can use Navizon for the same thing until the official SDK goes live.

I gave that a try on my N73 last night, kept getting the "sorry, not available" message.


Love the new Google Maps though, way quicker on V2.0.3 than the old 1.5.4 I was using.

Its sucky as a GPS but theres a lot of possiblities from knowing approximately where you are.

Beside automatically starting google maps in the right area, narby restaurants, etc (which is what its really for) the same info could start relevant weather reports and nearby traffic info (1-2 kms is good enough for traffic jams and clouds).  Theres a ton of other uses.

Say I always want my mobile on vibrate when Im at work but ringer on at home.  You could use the same info on location to auto switch between the two modes.  It could know which direction youre travelling in and automatically warn you about train delays at your destination only (who needs the info along the whole route - just where youre going).  Working out which airport youre in to only show you the relevant flights.  Automatically warning you about events like local football grounds kicking out, etc.

Its got a lot of potential for just making general everyday apps run that little bit smoother.  They shouldnt have called it GPS as everyone thinks of using it for navigating.  But I do like the idea if other people start to use it.

...snooze.... nothing new - this technology has been around for a few years (I have a few scripts that will do similar).

Thou this does mean that google can probably get your mobile number just from visiting the map site.

May I ask you a question about the scripts...

I have no doubt that you can pull the distance to the masts out of the internals of the phone (its fairly easy to pull that info out).  But how do they know the location of the masts to work out where you are?  Its all well and good knowing youre X/Y/Z kms away from three mast but unless you know where those masts are it doesnt help you.

Theres an app called Navizon out there that somehow does it but I cant work out how.  It probably uses the same method as those scripts.  Ive not seen any publically available list of locations for all the transmission masts so how are they working it out?  Googles just making their own database of every mast on the planet but these small companies cant have access to those kind of resources...

PS: The navizon one cheats and uses wifi to help locate itself.  Any links to the scripts?

nice - I was hoping those scripts had found another clever way of doing it I could use for a project but guess theyre using this.  Good find tho - appreciate it :)

You might be able to get the info from the phone but them method I use and the method that google will be using is to ask the operators. All UK operators (apart from Three) have an API that allows you to request the location of a phone.

I ought to let you know that I work for a SMS company and as such we have access to all sorts of things. Would be fairly simple for anyone to get an account with such a company and set up a rival product...
