Bonjour groupe,
The pre-processing procedure has been tested for the Squamish (BC) area. 
Squamish has a small number of buildings (6K) with a good Esri World imagery 
which need to be aligned with ODB data. A large number of ODB buildings show an 
inaccurate delineation (shaky drawing with too many nodes). Orthogonalization 
worked great but the result is not perfect because of the quality of the data. 
About 10% of the nodes were removed from the dataset. It contains all the 
problems we may encounter during this import. Consequently, I suggest that the 
import procedure be discussed and documented in detail using this case.
I could identify myself as the local import manager, but I would much prefer 
someone from the area to volunteer. When the local contributors have been 
contacted, and as long as there are no objections, we could start an import 
project in the OSMCanada task manager. Pre-processed data are available. We 
only have to make it available to the task manager. We also have to provide the 
task manager with the working areas (tasks) adjusted to 200 buildings per task. 
I am currently working to define these working areas, but if someone else can 
build it in the meantime it would be great.
Once the import project has been configured in the task manager, interested 
contributors will have to identify themselves in talk-ca in order to add them 
as authorized contributors (James, am I right?)
Would it be fun to try this?
