Christoph, the source data for buildings has 0 tags that need to be
translated as it is only building footprints and *0 attributes*. The source
on an Ottawa web site/federal website is non-existant for the time being
as: the city of ottawa litterally gave statscan a file on a flash drive to
deal with it: *this is precisely why I put background in the documentation
as the source for buildings will probably not be available from a official
website for years(judging how slow things move in the government)* you will
just have to accept that as it was handed to us from an official source the
two tags that were added were "building" and "source" polygon coordinates
are the same. If you really want I can strip all the
"properties":{"building":"yes","source":"City of Ottawa"} and it will be
the same file. We are using this as the source. You will see that there are
1000s upon thousands of tiny garages/sheds and other junk we probably don't
need in the geojson I have linked.
St-Germain Crescent (Saint-Germain Crescent and yes it's written that
way(St-))
St-Emmanuel Terrace (Saint-Emmanuel Terrace and yes it's written that
way(St-))
Des Forets Avenue (What's wrong with this? There are french road names
especially in orleans "Des Forest" means Forests in English)
We are aware of Jeanne-D'Arc and have corrected it manually (there are a
handful of roads we've Identified as "problematic", all in Orleans (french
part of town they decided to put french and english together)
*There are discrepancies between the street names in the address nodes and
the road names in OSM by the way, mostly due to wrong names in OSM
(probably due to bad previous imports).*
ORRRRRRRRRRRRRRRR the city of ottawa feels it necessary to rename a couple
hundred roads per year and just hasnt been updated in OSM.....
