Hi all,

The NTS Tile 084 is the 2nd tile has been successfully complete.
A big congratulations goes out to user osm.wiki/User:Stevens

You can see on the GeoBase map what the area covers,
http://geobase.ca/geobase/en/browse.do?produit=cded&decoupage=50k&map=084

and can see on OSM the southwest corner
osm.org/?lat=56.11&lon=-119.638&zoom=10&layers=B000FTT

This is a whole lot of roads, so this process will be slow & steady. This area would otherwise be VERY difficult to map.

We are using a system of 'RoadMatching'. In short; This is where we take the existing OSM roads, compare it with what exists in the 'to-be-imported' file, we then do an 'invert-selection', and only import the roads which are not already in OSM.

The process isn't perfect, however, it does answer the main concern of OSM mappers; To not undermine the work, and have geobase as an 'addition too', rather than a replacement.

This discussion is still on-going on the talk-ca list, so your all invited to check the archives, and join in the discussion with your ideas.

Notes and results are all being recorded on the Wiki page.

Cheers & great work!
