Hi Nif,
I have a different approach. The question of "how servers work" is
different, I'm rather focused on user perception of rendering. It would
be easier to list features like anti-aliasing, sub-pixel rendering,
compression algorithms, etc. But different combination of these features
may produce various effects and it's finally a complex task to determine
which one is the best (or fit better to a given objective). Moreover,
some feature like anti-aliasing are not always nice, it looks crappy
sometimes!
So, the question is about "how", sure. But it's the "how" of map users!
I'll soon publish a survey to gather users opinion (both experienced gis
users and novice map users) and I should release a report by the end of
november, I'll advertise it here if you're interested.
Regards,
Gilles
PS: I like your picture gallery, travelling through south america must
have been a great experience :)

Hi Gilles -
I was thinking...it seems that you are asking about the "how" of the
OpenSource cartographic servers.
Maybe the question is not "how pretty are the maps", but "what is the
methodology behind creating the maps and visualizing the math of the
data"? Is it topology based like a GIS? Is it like a low end CAD
product where the polygon is snapped closed, but when you look
closely, the beginning and end point do not lie on top of each other?
Stuff like that, that I remember studying, but don't remember the
details of.
I would be interested in hearing the answers to your question. I
hadn't much thought about the rendering of the data.
Good luck.
Cheers,
Nif
