Hi all,
Im please to see that SteveS has sucesfully imported the 092c area, this is the bottom left corner of Canada.

As you can see, the AutoMatch worked well, it was able to omit all the roads that OSM mappers added in, and only import the roads that OSM Mappers didn't get to yet.

On the coast road, which is from Victoria to Port Renfrew
(which was the road i cycled on 2 years ago, on my Bike Across Canada Trip :)
You can see the duplicate. This is because the OSM Mapped road continued on in 1 connected way, rather than a few ways with a relation. So the AutoMatch script didn't know what todo, and added it in. If the way would have been shorter and fit into an NTS tile area, it would have caught it.

So now what i'll be doing it getting in touch with all the mappers who worked on the area, and show them what was imported, and they can decide on how they want to merge the data.

If the OSM road is more complex in tagging, then (most likely) the mapper would want to retain it, and go through the process of adding in more nodes and refining the location of the way. ...
Or (like this hwy) there are a few BIG highway switchbacks which really should be clearly defined .. i think that no matter how many times you navigate that road it will be different. (unless your walking it)
But i wont touch it intill after consulting with the OSM mapper who drew in the road.
The map is zoomed out to about the size of the area. (excluding the USA at the bottom)
