[Talk-ca] Canvec.osm Product almost...

[Sam Vekemans]

(I cheat) I get an instant notification as soon as the wiki gets edited :-)

There are 10 areas as a result,

Perhaps an easy way to deal with it is for it to be listed on the
wiki?  So people can indicate what tile they are working on?
As well as host a mapping party for this?

I just had a look at the bottom right corner of it & see that it will
take some careful work and a lot has changed in the Vancouver area
since the data was created.

Others have also indicated to me (off list) that they are interested
in working on certain tiles with varing levels of experience.
And my recomendation is to message the talk-ca@ list, and also jump on
the #osm-ca IRC while working.  (so others know whats going on)

I have made the recommendation to upload a box around the area and
label it as 'under construction', so mapping in that area it could be
temporarly put on hold, as it does take time to work on it. (but i
havent heard back).   The draw back is that it will draw attention to
the area, and ther chance of 'bulk_implopping' (which we dont want) is
greater.

And it's also worth noting that many mappers are NOT on this mailing list.

Since im not local to that area im not importing any of them, :) as
there are more than enough mappers.   .. but i can make a trip over to
the mainland & do a demo for whoever wants to meet up?

Cheers,
Sam
