Hi,

 

Just let you know that I’ve completed Canvec Road and Building import in
Montréal area (south shore, Montréal, Laval and north shore).  It has been a
very tedious work to integrate Canvec to existing Osm data.  

 

Here are few comments (you probably know many of them but just in case
)

 

I used Canvec_to_osm to convert data and JOSM for uploading

-          Canvec_to_osm creates duplicate nodes at road intersections. I
was not able to automatically fix them using the latest JOSM (2561) and
Validator plugging (18848) - If someone has an earlier version that works
properly for duplicated nodes, there are still a lot of them to remove.

-          Canvec_to_osm associates tags to inner polygons, instead of outer
polygon, for relations. All have been corrected (buildings)

-          JOSM had sometime problems when uploading, creating duplicates
nodes/ways.  All have been corrected

 

 

Most frequent problems encounter with existing data

-          Hundreds of street name abbreviations. All have been corrected
(running on windows OS I must thanks notepad++ )

-          Dual carriage ways mapped as single line. All have been corrected
- at least those present in Canvec dataset – keeping the original one and
adding a parallel way with same attributes!

-          Usually no ramp/slipway mapped on streets.  Almost all of them
added

-          Usually no bridge tag used for viaduct. Almost all of them added 

-          Features captured using Yahoo! Imagery doesn’t always fit
corresponding GPS tracks (Compared to Canvec that usually does). Worst cases
have been corrected through nodes displacement.

-          Highway categories (primary, secondary, and tertiary, residential

) were a bit messy.  I’ve proposed a discussion on Montreal wiki page about
that topic but no answer yet.

 

Don’t you think we are creating fantastic maps!

 

Daniel

Subject: [Talk-ca] 092G03 NRN Import Complete

 

Well, I've just finished up the airport area, which makes 092G03 finished.
This also means that the entirety of Vancouver, the GVRD, and surrounding
suburbs are all done the import (092G01, 092G02, 092G03, 092G06, 092G07). I
covered the western half and Michael Barabanov covered the eastern half.

You can get the NRN .osm files for 092G03 from
