[Talk-ca] CANVEC Comments

[john whelan]

The new Canvec tiles are very good quality wise.  However when a
building or park is on two tiles it would be nice to combine the two
parts so it gets one name etc.  Has anyone worked out how to do this
in JOSM?

I use http://keepright.ipax.at to clean up Ottawa's existing roads and
I've spent many many hours connecting street junctions and floating
islands but I know I still have many more hours of manual clean up
ahead of me.  What I find the most difficult are the streets that have
been wrongly named.  Street qualifiers are the normal source but a few
times now I've come across three streets merged into one and given a
single name.  Very difficult to pick out and correct.  The numerous
streets with no name are easier to fix and the easiest source to use
for this is the CANVEC data.

What I find frustrating is the CANVEC data for roads appears to be
almost spot on.  I've come across two minor places where it doesn't
include a new road or part of an existing dirt track but if we were to
totally replace the existing road network in Ottawa with the CANVEC
data the quality of the map would be much higher plus you could then
run routing software on it and it would save me a fair amount of clean
up effort.

Most of the value add in OSM comes from POIs that are not part of the
road network so that value would remain.
