I have now succeeded in importing the Europe extract (I think at least, I
have not used it for anything ...). If my further usage of the database
is going to work well and nobody has objections or knows a better way, I
can put the steps into the wiki. The sequence of steps I used is
I was under the impression (having read that somewhere?), that the change
files could also be used to update a previous import of only part of the
planet. I remember reading, that this would also introduce nodes outside the
bounding box of the original import, which could then be removed from the db
later on (if it should stay restricted to the bounding box).
Unfortunately, I seem not to be able to update the Europe-import with change
files, because (obviously ...) nodes are missing for ways which are to be
imported (which are probably outside the bounding box). Is there a way to do
this?
The only idea I have left is to completely leave out all constraints from
the database (which would need another day at least for testing, I guess),
such that osmosis does not fail with the way (and relation?) updates. Is
that, how people are handling partial imports? Could this break further
actions in the database (inside the original bounding box that is; outside I
am sure, this will break ...), like extracting smaller parts into xml-files?
That's probably your only option. Applying changesets is almost
guaranteed to break referential integrity at some point until all
changes are applied. I don't have any great ideas on how to resolve
this one.
