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
Hi all,
I was able to split Squamish into Quadtree tiles with a maximum of 200
buildings each. James is now looking into whether/how this could be implemented
in the task manager. If no one else is volunteering to be the local import
manager this week, I will do the work and contact Squamish's
Bonjour groupe,
I should soon be able to feed the task manager with tiles containing no more
than 200 buildings each.
I will be using a Quadtree algorithm similar to what was used to split Canvec
map sheets. The problem is that the algorithm creates tiles that keep the
aspect ratio of the data
In some cases, the aspect ratio is 1:5, creating long vertical tiles (tasks),
or I may miss something :-)

Hello Tim,
Your proposal to use data from the city of Montreal, rather than that of
StatCan (ODB), is interesting but from my point of view, it is another data
import project because of…
- Different licence [1]
- Different pre-processing [2]
- Different data description [3]
I propose you build

adequate.
What do the others on the list think?

I have reviewed everything that has been written on the ODB import (aka Canada
Building Import) in Talk-ca and the wiki. I proposed changes to some wiki pages
(via talk tabs) to ease the discussions about this import and the following.
That is why I proposed changes in some wiki page (talk), to deal with many

The Squamish buildings are not as accurate as expected. It seems that they were
acquired through automatic image interpretation, with little validation. I
found many buildings with the roof correctly mapped, but one of the building
faces (visible on the imagery) was added as a roof component.
Sounds good to me. Can we try it as if I don't have the data? I might then be
able to clearly document the procedure in the wiki.

Hi all, here is a warning for those of you that import buildings. The latest
version of JOSM seems to fail in detecting crossing buildings (which is the
base of the import process). A ticket has been opened (#19053) to clear the
problem.

I am about to complete the Squamish test area and so far the new ODB import
procedure seems adequate. So, if you require the data to be pre-processed over
the selected area just let me know.
However, I would suggest using squares instead of various polygons to define
tiles because it is simpler
