Added Mac address to database but still inacurate...

It got even worse! It locates me now in the middle of the pacific ocean although I'm at home in the netherlands!!

that is a typical feedback when the iphone/google maps went into fallback, trying to access google cellphone tower data, and got a reply, but the data was empty. if you enter geocoordinates 0,0 0,0 you will end up just below nigeria!

did you check if skyhook has scanned your area?

if not why not apply as a driver? if you have a vehicle and 30-35h/week for 1-2months time... they pay €18/h. but it's a demanding job! not easy to do, you need to drive EVERY street in your supplied area. EVERY road!!!

http://skyhookwireless.com/careers/dr... you can apply there, just chose a city near you....

I don't want to be a driver but I scanned all the networks in my neighborhood and added them to the database. So it should be fine. And it was fine actually till a week ago. Now everything's messed up again! I added my wifi again so I'll wait till the database is updated and then maybe it works again....

right now only amsterdam (complete) and rotterdam (partly) have been scanned in the netherlands.

which area are you in?

I am at den bosch ('s hertogen bosch) but I added more then 15 networks myself here in the area so it should be fine...

yeah I know. Maybe I'll do this when I have my vacation and I have more time! Now I'm very busy so I can't do it now....

if you do it like this:

try to scan for all wifi-routers you can see in one location, not just one.

there's an application called APlogger for the iphone. you get the log file via SSH from the iphone after your done scanning. you can save different locations in one go.

then you enter the various wifi-router mac addresses in the skyhook mask later. the more frequent you scan, let's say every 50-100m, the more precise you can locate yourself.

so your in between eindhoven and utrecht. would be a good area to scan...

i would suggest you enter your info into skyhooks driver database with a date that you have time to scan... i think they're pretty flexible, when you don;t have time you just send the equipment back and when you have time again they will send it to you again...

if they get back to you you can still make the decision then, but if you don;t apply you won't have the opportunity...

Actually I'm visiting Eindhoven everyday! So that may be nice option to scan there! I'll contact them this weekend. maybe I can do some scanning in july! That'll be nice! thanks for your great help!

you would need to be able to drive around 5h/day, otherwise you can't drive every road in the assigned area. if you have the time to stay in a specific area and drive 5-10h/day for a couple of days you will be fine. but just driving through an area on the bigger surface streets won't do it.

the database needs to be as diverse as it can get to be precise. let's say your location. it would be good to actually scann 50-100m away from your house, in front, behind, to the right and to the left of it. then there;s a very good chance you collect enough wifi-routers to actually triangulated yuor position. if the database can only count on one wifi-routers mac address it can only place you in a radius of 200m within that area...

if your iphone sees let's say 5 wifi-routers that have 3 different geolocations in a 300m radius, the chance that it will get your loations within 10-20m of your actual location will be very high...

Why not let iPhone users (and others) submit matched Wi-fi locations and GPS locations automatically, then everyone will be "driving around".

The coverage here in Denmark is terrible and fine tuning is only for USA (???). If you have millions of iPhone users submitting locations all the time then this could really take off.
