how to fix incorrect GeoIP data?

I bet each company uses a variety of methods to build their data set, not
least of which is the one you mentioned.

I don't think the larger (and by larger, I meant the ones with the most
users) ISP community is so concerned about the accuracy of geoIP info, or
even need to follow the routes we do, but there would be benefit to everyone

And I don't think the interested members here on NANOG have the collective
ability (in this virtual world) to interest any of the mentioned geoIP sites
to work with us (NANOG).  The most successful strategy would be for a NANOG
member to work through their corporate (physical) channels to establish the
relationships, and then bring the rest of NANOG on board.

Sorry to rain on the parade, but face-to-face seems to be what it takes to
make things like this happen.

Perhaps we as the ISP community need to realise that we need to somehow 
publish this data (town or something alike) via some kind of standardized 

Right now I guess they use tracking cookies together with e-commerce 
account registration to deduct where an IP is from?
