The most comprehensive public domain spatial data is probably on the US, but
there is an awful lot of it on the rest of the world too. I've been working
recently with "VMAP Level 0" data, which is a 1.8 gig collection of
worldwide GIS data at a 1:1,000,000 scale. Yes, the scale is poor compared
with US data, but it's a good start. Additionally, if the project was able
to get a little bit of funding, there is a whole bunch more worldwide data
available through the Freedom of Information Act. All you have to do is pay
the FOIA copying fee for the CDs and the data itself is public domain.
A separate WikiGIS/WikiMaps project (we own the .com
and .org for
both names) would probably be needed to improve those data and create data
for
the rest of the world (also serve the result to all
Wikimedia projects as
a
part of Wikimedia Commons). *That* would be fairly
unique and difficult to
do,
since I'm not aware of any such similar project
based on the Internet.
I'm strongly in favor of this. In fact, I've registered
wikiteer.org and
have already begun working on it. I was planning on completing a prototype
before really pushing for support from Wikimedia, but if people are
interested maybe we should get started right away.
" the whole idea of copyrights on spatial data
seem to be absurd to me;
how
could anybody claim to *own* any exact digital
reproduction of the street
network for Paris or the exact location and shape of the Zaire River? "
While I agree with your sentiment (I don't even think software should be
copyrightable), the digital reproduction is by no means exact. As such, a
large number of choices have to be made, both in terms of selection and in
terms of how to most accurately reproduce the data. In this sense it's no
more absurd than a copyright on a digital photo of a paris street.
