At the first intersection, the text in French means "Wait for arrow to
turn left" which you can probably ignore. There is also a no U turn
sign.

At the second intersection, there is no left turn at certain times. I
think it says Monday to Friday 8am-10am and 3pm-7pm (Lun-Ven 8h-10h,
15h-19h in French) but it is hard to read. There is also no U turn
except authorized vehicles.

No right turn on red signs are pretty common. You definitely shouldn't

Urgent care centre is the official name. I think that when they are open,

(Does this mean that Hamilton can revoke our use of the data for

I am starting to work on importing Open Data datasets. I am using
pnorman's ogr2osm script with modified translation files (see
https://github.com/andrewpmk/ogr2osm-translations). It will be some
time before I actually import anything.

I would like to assemble a list of government open data portals in
Canada which are compatible with the OSM license. Please add suitable
open data sources to
[https://wiki.openstreetmap.org/wiki/WikiProject_Canada/Open_data]. If
they have already been fully imported then you should put a note on
that wiki page.

Also I am trying to figure out a way to import newer CanVec data. The
CanVec files in OSM format at http://ftp2.cits.rncan.gc.ca/OSM/pub/
are out of date and appear to have been created in 2010. Is the script
that was used to convert CanVec to OSM open source? It looks like
there is a new version of CanVec called CanVec+, has anyone here used
it yet? I am hoping to do something about the large amount of broken
imported data in OSM in Canada and we need a better way of fixing
broken CanVec data than copying from the Geobase WMS layer or cutting

See http://wiki.openstreetmap.org/wiki/CanVec. CanVec data was
converted to OSM format and is stored at
http://ftp2.cits.rncan.gc.ca/OSM/pub/, and is split into files based
on the National Topographic System, and then data was imported in some
parts of Canada by manually cutting and pasting data from these files
into JOSM. I did this in a large part of southern Ontario and some
other users have done this as well. Importing CanVec data this way and
correcting all the errors is tedious and hasn't been completed for all
of Canada, and I haven't done very much with this for several years.
Before this was done there were more primitive imports done, perhaps
around 2008-2009 or so, and these imports are extremely low quality. I
can't remember which OSM user did this. When OSM was new there was not
much data in OSM, so a lot of imports were done and many of these
imports were poor quality; now that OSM is more mature, imports are
increasingly viewed unfavourably and there is a general attitude that
data should be collected by surveying whenever possible.

It would probably be best to use the newest version of the Geobase
National Road Network (http://www.geobase.ca/) and compare this to the
data in OSM and make corrections that way. Keep in mind that this data
has errors and municipal datasets (where available) are always better

Re: [Talk-ca] OSM data quality in Canada

[Andrew MacKinnon]

 A lot of the data in Canada was imported from CanVec and Geobase,
some of it by me several years ago. The imported data is pretty poor
quality in many places. I haven't done much work on this recently, as
imports have a bad reputation in OSM and I am mostly concerned with
surveying. For example:

- Some older road data comes from an import which combined CanVec and
Statistics Canada road names, attempting to match the road names in
Statistics Canada with roads without names from CanVec, and this data
is poor quality.
- Road data in some areas is missing entirely.
- The CanVec address data is low quality, and is often broken - e.g.
on a tile boundary address ranges will be split in half, and comes
from several different versions of CanVec.
- Other CanVec layers such as woods, lakes and so on were imported in
some areas but not others. Much of this data is low quality.
- Some road names have too many spaces e.g. John Street is John
Street. Some address ranges are like that as well.
- lanes=-1 and surface=unpaved for roads that are really paved in Quebec.
- Better quality municipal GIS datasets are now available in some
cities like Toronto, Peel Region and York Region and if they are
properly licensed, these should be used whenever possible. There
generally are some minor errors in these datasets, but they are far
better quality than CanVec/Geobase.

I really like the TO-FIX Tiger Delta layer at
http://osmlab.github.io/to-fix/#/task/tigerdelta which matches TIGER
data with OSM data and tries to find errors. It would helpful if a
similar tool were created for Canada.

 I believe these mostly affect Quebec, but there are two import problems that

Re: [Talk-ca] RIP CanVec

[Andrew MacKinnon]

I have to say that fixing existing Canvec data is a higher priority
than importing new Canvec data. There is a lot of broken Canvec data
that needs fixing, especially in Quebec (particularly the Montreal
area). For instance:

- Address interpolation lines split in half
- Road name does not match address interpolation way (usually means
that a road is missing). In many places in the Montreal area roads
have
- Double spaces in road names in address interpolation ways - e.g. Rue  Peel
- surface=unpaved for roads that are really paved in Quebec
- lanes=-1 in Quebec (most but not all should be lanes=2)
- Inaccurate natural=wood ways that should be deleted

http://tools.geofabrik.de/osmi/ (particularly the Address view) and
http://osmose.openstreetmap.fr/ and http://keepright.ipax.at/ will
help you find a lot of these.

 Objet : Re: [Talk-ca] RIP CanVec

 Bonjour,
 À mon humble avis, après que plusieurs avis pour et contre Canvec aient
 été échangés (et j'appuie la majorité de ceux-ci), il serait von de
 recentrer le débat:
 Gardons tous en vue qu'OpenStreetMap est avant tout une carte citoyenne et
 que c'est à chacun de nous d'enrichir les données, tant sur le plan
 qualitatif que quantitatif.
 Donc après avoir argumenté pour/contre Canvec, l'amélioration des boisés,
 plans d'eau, interpolations etc est entre nos mains...
 Se décourager devant l'ampleur du travail ou bien éditer un jour à la
 fois c'est en fonction du dynamisme de nos communautés locales partout
 au Canada, que nous obtiendrons un beau résultat.
 Pour les Laurentides, la communauté de la Province du Québec tente de se
 structurer et le noyau de contributeurs de Montréal et Québec autour de ce
 projet pourrait vous venir en aide.

 I've recently imported some CanVec 10 data into the North Bay, Ontario area.
 It's been hard to figure out the best way to do this because of the assorted

 Since this is the first time I've imported any CanVec data, I am wondering
 if this is the best way to do it when there is existing data in the area. I
 would really appreciate it if someone could take a look at my import in case

Your import looks fine to me.

In areas with existing data, you need to merge the existing data with
the new data, by cutting and pasting new CanVec data into OSM and then
merging it with old data (by joining roads that you copy from CanVec
with existing roads, and cleaning up any old imported data that is
inaccurate e.g. roads with the wrong name). This is time consuming but
necessary.

When you import street address data, please join the imported street
address data with address data from adjacent CanVec tiles. This is
very time consuming but needs to be done properly. Also the
FixAddresses plugin in JOSM might be helpful to compare road names
of imported street address data with road names in the database,
although you should only use it on a small area, as it is really slow
if you try to use it on a large area.

Re: [Talk-ca] Canada Post addresses that do not match municipality name

[Andrew MacKinnon]

OK I've figured it out.

In the City of Toronto, there are numerous duplicate street names
caused by amalgamation. See
http://finance.groups.yahoo.com/group/ontroads/message/9826. If
there is a duplicate street name, you must use the name of the former
municipality in the address e.g. York, East York, Etobicoke,
Scarborough, North York. If it is not a duplicate, either Toronto or
the name of the former municipality are acceptable. Various other city
names like Downsview, Don Mills and Weston are acceptable for certain
areas of these former municipalities, these are generally just aliases
for the old municipality name (though Downsview for instance is only
accepted for the portion of North York near the community of
Downsview, using Downsview for an address at Yonge/Sheppard is
incorrect).

In Markham, there is the weird situation of Main Street Unionville
and Main Street Markham.

In other parts of the GTA, sometimes the city name used by the post
office doesn't match the actual city's name, but I can't find any
other examples of duplicate street names other than the one in
Markham. If an address is Woodbridge or Concord we can pretend it
is in Vaughan.

Since the Canada Post database is proprietary I have had to figure
this out from sources like receipts from coffee shops and fast food
restaurants. Fortunately these are easy to get.

Is a free source available for the boundaries of Old Toronto, North
York, York and East York as they existed before 1998? I have added the
boundaries of Scarborough and Etobicoke as boundary=administrative,
admin_level=10 which seems to make nominatim work propertly (though it
says that the addresses are in Scarborough, Toronto, Ontario, Canada
instead of Scarborough, Ontario, Canada which is not the correct
format).

 I'm curious why you would trust the Bing imagery more than canvec. In
 addition to not being very high resolution, I would think that Bing
 would suffer from problems with registration (alignment of images to
 lat/lon) which would have to be checked against ground readings. Of
 course canvec should also be checked for accuracy with local readings.

 Further, my understanding is that much of the canvec data is generated
 from local surveying, which uses high end GPS which are extremely
 accurate.

 Locally (Kitchener-Waterloo) I have found that the canvec data is very
 accurate and most imagery less so.

I have been using the Bing imagery where high resolution imagery is
available and Canvec where high resolution Bing imagery is not
available. My impression is that for coastlines, tracing from Bing
imagery is more accurate than the Canvec data.

Keep in mind that some of the Canvec data is VERY out of date. While
the road data in Canvec is fairly up to date, the rest of the Canvec
data seems to be old (1990s, 1980s even?) Canvec data shows woods,
buildings etc. which clearly haven't existed for many years, for
example it often shows forests in areas where new subdivisions have
been built recently, old industrial buildings which were torn down 10
years ago and replaced with housing, long-ago abandoned rail spurs to
industrial areas and long-demolished agricultural buildings. I would
not trust anything except the roads layer in Canvec to be up to date.

 It reflects the fact that there is no more complete map update program at

Great, so I wasted the last several years mapping Toronto :)

(I am exaggerating here, because there is a huge amount of data which
simply isn't available in these datasets, and must be added manually.
For example, the location of shops and other businesses.)

Looks like there is a huge amount of data here. Road centerlines,
addresses, park boundaries, some recreational trails, rivers, churches
and a few other things are all in shapefile format and can be imported
easily. The challenging part will be combining this data with data
that was mapped by hand or that is from GeoBase. Unfortunately, as far
as I can tell, the road data does not include grade separations
(bridges/tunnels), it represents dual carriageways as a single way,
and it does not include one way streets (unless I am missing
something).

TTC routes and schedules are available, but in a weird undocumented
text format (not Google Transit Feed Specification or something
standard like that). I have absolutely no idea how we will import this
data.

Various other data, such as property parcels and aerial imagery
(hopefully higher quality than Yahoo) is available through a Web
Mapping Service - it suggests that you use ArcGIS Explorer
(proprietary software) to view it. I'm not sure if there is any way to
view it with free software. Since this is presumably raster data, it
will have to wait until later.

The CanVec data is junk compared to the City of Toronto data, so I
think we'd be best off not importing it at all.

Since this is such a complex job, I think that we need to arrange some
sort of meetup (either in person or on IRC) to discuss how we will do
this import.

 I think the addressing data will be a nice addition to OSM.  They
 haven't released the parcel data yet, but they have it and might
 release it.  The TTC data is for street cars and buses only so far.

The centerlines data is up to date - it shows several roads that I
know were built recently e.g. the Simcoe Street extension under the
train tracks and the renaming of part of Duncan St to Ed Mirvish Way.
However, we are probably best off keeping the existing road data (most
of it manually added by me from GeoBase NRN), and not attempting to
use data from the centerlines shapefile because the city centerlines
data shows dual carriageways as one road and does not show grade
separations, unlike the GeoBase data. There is no reason that we can't
copy missing features from it though.

There is quite a lot of raster data in the WMS layer City GeoSpatial
Web Service. This includes much of the data in the shapefiles, such
as road centerlines, trails (though some minor trails are missing or
inaccurate), rivers (with names, many of which are missing in OSM
right now), and address data. It also includes parcels, but only in
raster format. It might be useful to trace features from here in JOSM.

The TTC data is pretty much useless to us because it is in a weird

 I haven't yet dealt with the TransLink data yet, so i have no idea what the

 Wholesale deletion of the work of many volunteers without their

 would consider that wholesale deletion to be vandalism.

I strongly agree. Manually edited data should never be removed and
replaced automatically with a data import. Imported data likely
contains errors and omissions and does not contain additional
information (such as one way streets and POIs).

Instead, one should clean up the data by surveying and by using
validation tools such as keep right (keepright.ipax.at). To clean up
an area quickly, it may be useful to copy and paste missing data from
GeoBase, as it is generally fairly accurate (though it does not
include one way streets, and new roads built in the last few years
tend to be missing).

like the satellite photo. Not 100% sure about this one, haven't
reverted it yet.

http://www.openstreetmap.org/browse/changeset/2227665 - northern
extension of York Regional Road 99 (extension of Highway 427) past
Zenway Boulevard to Langstaff Road. Very inaccurate, but plausible
since this extension is planned in the future (though Wikipedia says
it hasn't been built yet). Can anyone confirm whether this exists yet
or not?
