I took a look at a bunch of cities around Europe, North America and
some of Asia. I convert the OSM data into a compressed vector form
that scales pretty linearly with node density, way density and POI
metadata. For these cities, I try to fit as much city as I can into
less than 20MB. I use Lambert Conic projection to try to reduce the
latitude spread effect. Short answer, less data means larger area
of city. Paris has the highest density in the world (I fit 16 4km x
4km tiles in 20MB), Boston has the highest density in North America
(49 tiles).<br>
<br>
You might be able to do the same just looking at the size of the PNG
tiles at a certain zoom, but PNG tiles will grow in proportion to
the number of edges in the scene and some ways (like dotted paths
and rail) would give a disproportionate density. <br>

My sample for Asia is a bit weird - these are both city states so
expanding doesn't make a lot of sense. Singapore takes 213 4km x
4km tiles to total 3.4MB. Hong Kong takes 503 tiles to make up
4.9MB.<br>

My data doesn't include turn restrictions and bus route data so I'm
blind to that effect on the data. Because buildings can contain a
lot nodes, it's possible that cities with a lot of buildings look
denser to me than others.<br>

<br>
I'd like to see some non-EU quality analysis as well, and I am
willing to work on it too. Right now I am just getting settled
here in the US and doing some mapping locally, but next on my list
is doing some quality analysis for at least some major US metro
areas.<br>
<br>
If you find anything along those lines that is done already,
please share. I have not really looked all that hard but from my
previous inquiries into quality analysis, I found most tools /
results to be EU based. I would think Cloudmade or MapQuest should
have something to say about this - Nick, Ant?<br>

Hi there,<br>
<br>
well I'm looking for somekind of research/stats on the quality
of our<br>
project especially in US or Asian area.<br>
<br>
I browsed the most of the scientific papers at<br>
<a moz-do-not-send="true"
href="http://wiki.openstreetmap.org/wiki/Research"
target="_blank">http://wiki.openstreetmap.org/wiki/Research</a><br>
but that ones, that concern the quality (and it's metrics) are
mostly<br>
focused on the EU area.<br>
<br>
So did I missed something and there is already a report
covering diff.<br>
metrics of other continents?<br>
<br>
P.S. Yes I know QSMatrix for sure (which is pretty cool), but
this<br>
doesn't cover non EU, too :(<br>
