of Asia. I convert the OSM data into a compressed vector form that

For these cities, I try to fit as much city as I can into less than
20MB. I use
Thanks for your work John!
I need to take a clother view if I have a bit more time for that.
Well I guess what Jaakko says is partly true. Mssive Data (see e.g. the
fat imports) doesn't show up how good (here lively) the quality of the
data is. thats why I personaly like OSMatrix as you can
If you are looking for an aesthetic metric for quality, you are probably
looking for a human to evaluate quality. I would argue that most of the
cities in North America (save Boston and maybe Toronto) quality is poor
because there just isn't enough content. New York is a wicked example
