I was wondering if my iPad had gps, which it doesn't. I seemed to enable
tracking in google map. Is it mostly using only my wifi, since it does not
usually see any other networks, except on occasion, and if I'm outside.

Ipad 1, 2, or 3?  Wi-Fi only or Wi-Fi plus Cellular model?
The GPS feature is part of the cellular chipset.  If you have a Wi-fi
only model, there's no GPS.  

See the Location section at:

Wi-Fi only:                Wi-Fi Plus Cellular model:

It's iPad 1 wifi only. I notice a circle centered on a marker, usually off
by more than 100 feet. Perhaps it can find location of address of owner ?
With some very weak signals at camp, it still was in the vicinity. I need
more time using it at different locations to see how it acts.

I just realized there is also a compass function.

No GPS in the first version.

Apple uses Skyhook Wireless to do their location services via Wi-Fi:
<http://www.skyhookwireless.com
<http://www.skyhookwireless.com/locationapps/
Accuracy is largely based on their database.  The way I *THINK* it
works is that when a device with both Wi-Fi and GPS enabled visits a
coffee shop, it sends both the Wi-Fi MAC address and the GPS location
to Skyhook Wireless.  Skyhook then "corrects" the Wi-Fi location to
more accurately agree with the GPS location.  Eventually, you get a
fairly accurate location by MAC address.

Disclaimer:  This is a guess, this is only a guess, etc...

Re: triangulation
Well yeah, but not limited to coffee shops.;-)  You are spying for Apple  
all the time. Well unless you use an Android phone. Then you are spying  
for Google. The damn google street view cars also collect MAC addresses.  
That is why they were sniffing wifi. The payload theft probably was  
accidental, though I have no problem with them being fined.

The Google database is such that you need to be sniffing two wifi  
devices at the same time in order to get the location. It used to be  
one, but somebody realized such a database was kind of intrusive since  
you could harvest MACs by one means, then find the location from the  
database. The idea is if you have sniffed two macs at the same time,  
then you probably ARE at the location in the database, so in theory it  
is not an invasion of privacy, well at least by Google's loose  
standards. [Of course, Google standards are higher than the NSA.]

THe ipod touch uses the same scheme.

They have every access point in my office building accurately located
to within about 30ft.

Hot off depresses... You can now allegedly opt out of the scheme:
<https://support.google.com/maps/answer/1725632?hl=en
by adding "_NOMAP" to the tail end of your SSID.  Note the unfinished
web page and useless detail, the mark of a rush job.  I wonder what
went wrong this time?

However, if do want to be located, or want to ruin someones day by
adding them to Google Maps, Google can help:

Re: triangulation
The free map isn't particularly detailed. I suspect it just shows the  
Central Office. They give you the name of the Central Office, which you  
can then google to get a location from a number of vendors.

My cellphone was with the wrong vendor. I'm not particularly surprised  
Verizon would sell such information.


I'm sure there are similar nasty companies out there, and you need to  
remove yourself one by one.

cidlookup.com links back to tnid.us
callowl.com links back to tnid.us

mobile.am never seems to finish. Well unless it is trying to download a  
virus. It just spins and spins.

This one claims to have found my name and address, but doesn't show it:

Well I give tnid.us some credit. They at least have the decency to let  
you opt out.

www.trackthenumber.com out of business. Maybe there is a god.


Ya know, in the EU, they are working on this "right to be forgotten".  
Given how we finance elections in the US, that will never happen.

Skyhook was using their version of Google Vans as well. I don't
know if they still are. But in the GOod Old Days they'd  
grab the wifi SSIDs and mark the GPS locations, and u/l
it to their data base.

They also have manual customer input. If you activate "loki"
and it sees unidentified SSIDs, it asks you for your location.
WHich then gets into the data base...

ah: https://en.wikipedia.org/wiki/Skyhook_Wireless
  

There were some legal battles..
