Yes, the import seems to be quite a selective process! Very tedious at times. And now that I am getting into areas where there actually is some existing OSM data and I have spent so much time hand editing in the past, I'm pretty careful to select the better data on a way-by-way basis. Sometimes the CanVec data wins out, sometimes not.<BR>
<BR>
In regards to simplifying, however, I am quite pleased to note that I have not seen displacement or removal of a node that sits at the edge of a tile. I'm sure they are just taken as end points. Simplifying a feature that will ultimately run from one tile to the next still yields duplicate nodes at the boundary when the next file is brought in. The stitching procedure is the exactly the same. Merge nodes and combine ways where appropriate. I just think it is a great tool that admittedly may only have limited applications. But I think that this situation is definitely one of them.<BR>

There are always issues when you want to replace one set of data with another. People may have added labels such as the name in French, replace the import and you lose the French.<BR>
<BR>
Where the CANVEC tiles meet ways are connected by overlapping points. Any simplification at this point that moves a point on a way means the way doesn't get joined where the tiles meet.<BR>
<BR>
This is why it''s so tempting to start over from CANVEC 7 then add in the detail, amenities, shops etc. At least you can have confidence that the road names are correct.<BR>
