<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">OpenStreetMap is highly decentralised which is both one of its strengths and also one of its weaknesses.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">There
are a number of sources of building data, the first is an experienced
mapper adding in buildings with something like JOSM and the
buildings_tool plugin working from Microsoft imagery. Esri, and Maxar
and Mapbox satellite imagery are also available. That one is the least
contentious and is acceptable to everyone.<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Second
is iD which is the default mapping tool on the OSM web page. You can
map buildings accurately with this one but in inexperienced hands you
get some very poor results. Pierre noted in disaster mapping with new
mappers the results were really very bad. There is something called a
mapathon where inexperienced mappers are invited to map. Yes it gets a
lot of data into the map but the clean up effort required afterwards is
fairly horrendous. Stats Canada pilot project was going to be based on
this until they were persuaded to go Open Data and use the City of
Ottawa's Open Data and the import process.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">In
Ottawa today practically every building has been mapped and has the
correct address. There are one or two new buildings that haven't yet
been added to the map. It took a fair amount of effort and organisation
and included help from Mapbox. One problem was the license for the
data. Toronto has Open Data but the license has not been confirmed to
align with OpenStreetMap.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Although
there are guidelines the authoritative body in OpenStreetMap is
consensus of the local mappers. So Ottawa local mappers decided the
import could go ahead, were very involved in it and were happy with the
data quality. We'd seen iD mapping of buildings before and the City of
Ottawa data was fairly good.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">After
the pilot there was no serious money available at Stats so the second
part was going to be "community led". They managed to talk to various
municipalities to allow them to release the municipality data under the
Stat Can license. Following a discussion in talk-ca I put forward the
formal import plan. The data quality was different for each
municipality and was questioned.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Normally
you look at the client requirements to see what is required. This is
something that OpenStreetMap very rarely does. Mappers basically map.
Each has their own individual standard of what is acceptable. For your
purposes if the angle of the corners isn't quite 90 degrees it really
doesn't matter. What you're interested in is something within two
meters of the right place. However consensus requires agreement from
everyone.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">However
the problem for you is the local mappers in Toronto and I assume York
would like a higher standard even if it means fewer buildings get
mapped.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Today
we have two other sources of building data that could be imported. One
is the Microsoft building data and the other is NR Can LiDAR data but
neither are much use without the local mappers support.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Some
courier companies have hired mappers to add data to the map.
Bangladesh is one area where this is done. Some are very good, some are
not so good. I don't recommend this route, one danger would be they'd
just import the Microsoft buildings and charge you for mapping then
someone would challenge the data and have it removed. </div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">If you have a specific problem area email me directly and I have been known to add in buildings with JOSM.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Once
we get the building outlines added then adding the address is fairly
simple with a smartphone and something like StreetComplete. Also Stats
Canada has address information that can be imported.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Does that help clarify and define the problem?</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Thanks</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Cheerio John</div></div><div class="gmail-yj6qo gmail-ajU"><div id="gmail-:15v" class="gmail-ajR" tabindex="0"><img class="gmail-ajT" src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"></div></div><div class="gmail-HOEnZb gmail-adL"><div class="gmail-im"><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 30 Sep 2019 at 22:03, Eric Geiler <<a href="mailto:eric.geiler@abcourier.com" target="_blank">eric.geiler@abcourier.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal"><span style="color:windowtext">We are a
local/regional courier and trucking company in southern Ontario with a
decent sized fleet. We are using Mapbox for our mapping / nav engine,
therefore subject to using OSM data. We have noticed
a number of “issues/lack of data” for southern Ontario. This ranges
from lack of lane info, to lack of buildings, missing streets, missing
exit/on-ramps to for Hwy 400 (which we added, and had Mapbox expedite
the changesets) as it affected navigation for
our drivers.</span></p>
<p class="MsoNormal"><span style="color:windowtext"> </span></p>
<p class="MsoNormal"><span style="color:windowtext">We are currently
using a few devices to provide street level imagery via Mapillary, with a
push coming shortly to map 1000km per day of street imagery. We are
currently mapping about 250km per day in York
Region. Our internal goal is to provide /gathered street level imagery
for 75% York Region by end of January 2020.</span></p>
<p class="MsoNormal"><span style="color:windowtext"> </span></p>
<p class="MsoNormal"><span style="color:windowtext">We are not in a
position to provide map edits etc, as due to staff resources and lack of
experience, our staff are not suited to become ‘map editors’ as our
core business is transportation. We are just trying
to assist the editors with accurate ground level info.</span></p>
<p class="MsoNormal"><span style="color:windowtext"> </span></p>
<p class="MsoNormal"><span style="color:windowtext">I would be
