<DIV></DIV>I haven't seen any issues with the simplify tool breaking joins or
any errors introduced by its use in the data sets I've been importing but then
I've only been applying it to water features... again, just to get the data size
for streams down to something reasonable. No other features seem to need
it. <BR><BR>Maybe I don't understand the process, but I can't see how
simplifying now would have any effect on future imports. If future
versions of CanVec were provided only as some sort of diff file, and new ways
relied on the existence of certain nodes in a previous data set, then I could
see a potential problem developing. But otherwise, I don't see how it
would cause any problems for future
updating.<BR><BR>Sam<BR><BR><BR>-----Original Message-----<BR><B>From</B>: Adam

11:37:40 -0800<BR><BR><PRE>Does simplifying like this cause issues where one feature joins up
with another feature? I'm assuming that JOSM won't move end nodes of
ways during simplification, so rivers connecting to lakes should be
okay, but what about places where there is a common node in the middle
of a way? Are there instances of this in Canvec, or does the Canvec
conversion process always split ways where there are nodes common to
more than one object?
If you simplify ways today, how will that affect imports in the
future, when the next version of Canvec comes out?
