[Talk-ca] GeoBase2osm & canvec2osm script making

[Sam Vekemans]

Thanks,Well, it might not help as much as i thought.
Anyway, I'm wondering about weather or not your planning on having  another
script that would be able to import the road names? .. . or you think it
would be better off that they get manually entered in, from survey?

I guess that as long as the data shows the same tag reference, it doesn't
really matter what method was used. Right? I think so.

As im going through the process for creating the Canvec2osm script, im
wondering about the usefulness for the NID, with respect to weather or not
buildings / railways... (all relevant CanVec), different than GeoBase, this
source tag would need to be "Geogratis.ca CanVec Import 2009"

So the big question:  is there really a point to adding the NID for this
CanVec data?
... since we will be adding and enhancing the maps after the import, the
imported data will become meshed and melded into to OSM Map.
...
Ie.  I import all the buildings, then add in more buildings that weren't in
the set.  There is No need to try to figure out what the NID is of it. .. as
the update set would be used as a reference and imported the same way.  >
 having both layers visible, then copying the features that need to be added
to OSM, then add more tags to make the feature more relevant.
<open question: Is this issue discussed enough on the wiki??>

Cheers,
Sam
