Hi RK,
Are you sure that your phone was able to get a GPS position with that
time? Would surprise me actually.
@hanno could you take a look at that data and see whether all timestamps
(not upload but capturing) are from 1970?
If they are not then their cause would be something different and they
haven't been uploaded by RK.
Ichnaea shouldn't allow uploads with time stamps that are before 2012 or
something (service start) and do a queue to delete those.
MozStumbler could warn users and refuse recording/uploading data when
the phone's clock is off the real date. (timestamp < build date
timestamp (for new data) and timestamp < ichnaea time stamp (for data
that hasn't been uploaded yet))
Regards,
Felix/Djfe

Hi everyone,
I was able to identify the source of errors for these observations. Turns
out, those were readings taken when my phone's clock was messed up. Date on
my phone during that time was sometime in 1970. Those resulted in wacky
computed GPS positions. What do I need to do to help you remove the
erroneous data? Right now, it's making it rather hard to see which spots on
the map are not yet covered in the Metro Manila area. Thanks!

Yup. That's low accuracy data from a WiGLe import(data's mine, WiGLe

recording even when I'm indoors, hence the very low accuracies, in the

I assumed those lines might be airplane routes, but low accuracy data
makes more sense. :)
You can also see off-road routes from devices that have GPS calibration
problems. In San Francisco, you can see some stray lines (that are not a
ferry) running parallel to the bridge:

air planes shortly crossed my mind too, but all those pilots would have
had to fly in remarkably straight lines & land in rather built-up areas ;-)
but thanks for the clarification RK
