[Talk-ca] Re : Administrative Boundary

[infosbelas-gps at yahoo.fr]

Daniel,
In parallel of of the excellent work you are doing for these imports, I suggest that we pursue the discussion on other aspects since the discussion was going in all directions in 2009-2010.  We must have some reflexions on how to import this data properly.


We now have a very good map of Canada but Nominatim Searches are limited since in general (at least for Quebec) there are no administrative limits other then provinces. I think that we all agree it should be a priority to define these administrative limits and assure that we have efficient Nominatim searches. 


This information and existing boundaries (ie. provinces, international boundaries) should be treated carefully to assure that Nominatim searches work properly.  We already lost some shorelines. Lets not loose our borderlines!


One aspect I think of is when a way overlaps existing ways. I dont know if this has been discussed before. When a way describing the limits of a town or a region overlaps other levels (ie. province, international borders), do we keep this way independant or integrate with the other information ? And it would be better I think to keep administrative boundaries information separated from other Canvec file imports.
