Reading between the lines of this question, (and if i'm getting it wrong,
asking a related question...)
If there is an area that has a licencing problem with it's data, for example
it's data came from a source that is not ODBL compatible, how do we get rid
of the old licenced data, without
If somone were finally to solve the problem of matching up traces to ways,
we would be in a position to extend that to identifying some map errors,
such as missing ways, or changed road layouts.
how to present this information in a useful way is a diferent task, but
worth keeping in mind.
Could
Fundamentally this is a simple application of some of the shortest path
algorithms that are studied at university computer science and mathematics
departments adnausium.
There are however a bunch of complications that make it a little less
simple, and is likely best worked out in each individual
So we can assume that a bounding area for what we are interested in will be
supplied;
Assume that there are no oneway systems in place unless that data is already
on the server;
Assume that all roads are equally passable unless otherwise staed in the
database (either by speed restictions or
I've long considered that it would be good to have a system whereby anyone
modifying a specified subset of the database would be presented with a
message for them to read before comitting.
This would be implemented with a special key that all editing software would
be encouraged to support.

I'm going to go back to some of the primative concepts of OSM here, just to
make sure that everyone is on the same page...
OSM has 2 completly destict concepts, tracks and ways: (I am simplifying
here, but you get the idea)
Tracks are a collection of gps points, as they are recorded, generally 1
if it's just the highways you want -- the data could easilly be filtered on
velocity -- include only the stuff thats 30mph. (i've done this in the
past, and it's a bit of a pain to do, but it's simple once you have it set
up)
in that case, all the superfulus stuff, as well as camp sites, tracks,
There is a massive difference between knowing what area somone lives in and
knowing thier exact address -- I'm happy with people knowing which housing
estate I live in -- if somone wants to come to the area just to find me --
they will have to knock on 300 doors (t-888 style).
However from traces
to do that.
I've spent quite a while processing gps stuff lately, and may well be able
to come up with something, what are the exact parameters of the data and the
conditions applied?
