Hi Mojgan - this is what really impressed me with your planned process:
that you're prepared to develop an elegant QC system to match up road
ways to address ranges.

Using municipal data imports alone wouldn't get this kind of QC, and
we'd end up with with millions of address points rather than more
compact ranges.

 Stewart

[Talk-ca] Metrolinx: OSM Golden Horseshoe Address Data

[Stewart C. Russell]

Hey,

We had a couple of folks from Metrolinx (the GTHA/Golden Horseshoe
transit agency) at the Toronto Mappy Hour last night. Their Triplinx
route planner — http://www.triplinx.ca/ — consumes OSM data for
addresses. They want to find ways to work with the community to improve
addressing in their service area. They're mostly concerned about getting
better address ranges than individual points.

I don't know what their next steps are, but they seem to be approaching
the community in a different and slightly better way than most agencies.

cheers,
 Stewart

Taking a look around the data in OSM for Toronto, it would appear that the
address interpolations have been added via import from CanVec already,
Pierre. Which prompts the question as to what, exactly, did the people from
Metrolinx mean when they expressed concern about "getting better address
ranges than individual points". The current data is in address range
format. So are these inadequate (either that they don't cover the correct
spaces, are incomplete or missing) or are they looking for addresses to be
attached to specific buildings?

The issue has come up in Ottawa as well, some street names or incorrect,
the city has been correcting them but there are some hundred to be changed
when I spoke to the person at the city.

CANVEC address import seems often to have been done by different people in
different ways and in Ottawa many of the CANVEC version tags have been
removed so you can't be sure if its CANVEC or not.

It probably needs something like a HOT tile project over the city so that
it can be gone over.

Re: [Talk-ca] Metrolinx: OSM Golden Horseshoe Address Data

[Kevin Farrugia]

Afternoon everyone,
Metrolinx is looking at adding missing address ranges - either those that were 
never added in or those that are in new neighbourhoods.  I believe they're also 
looking for problems where the street name on the highway doesn't match the 
address range street name due to spelling mistakes, different sources, etc.

Indeed. I checked before sending my email, but I zoomed in a place where
there is no CanVec address interpolations data, what I wrongly
extrapolated city-wide.

Sorry for both these irrelevant messages.

If you need a HOT task manager. I am currently hosting it on
tasks.osmcanada.ca. If you want to become a project manager just send me an
email after you've logged in, I can set you as one.

[Mojgan Jadidi]

Hi all,

Thanks  Stewart for initiating this discussion, I am one of the folks
working on OSM data at Metrolinx. We are currently working on OSM data of
our service area to improve the address range information for route planing
purpose.  Our concern is improving address searching issues for the service
based system using OSM as basemap. Our area of interest is Greater Toronto
Area and Hamilton, mostly in new subdivision areas. Our conflation methods
is based on an in-house algorithm of buffering left and right sides of the
street segments to detect the missing parts, following with an extensive
visual inspection (walking though all new data on OSM base map).

We are going to publish our wikipage soon in OSM webpage and give more
details.  Metrolinx is an young agency with spirit of young professionals
for open data and open source software. Hopefully we will have
constructive feedback from the communities!

Thanks for your support,
Mojgan

Most of the address data in Toronto is from CanVec and I imported it a few
years ago. You might want to look at open data from cities like Toronto and
York Region which have more detailed address point data. I started
importing Toront address data a few years ago but never finished because
merging old data with new data is difficult.
