Re: [Talk-ca] Talk-ca Digest, Vol 140, Issue 11

[keith hartley]

Hi All,
As a guy that works with postal codes and carrier routing, Justin is right,
like the US, in Canada, Post codes are really just a sub-collection of
address codes that don't necessarily correspond with geographic areas. They
can be plotted on a map if you know the addresses, but they aren't polygons
like everyone thinks. It get really complex when you have ranges within
ranges (ie a street range, then a couple of condos within that range)
All I can say is keep pushing the gov't to open it up. It's a REAL pain to
maintain!

Re: [Talk-ca] NRC building footprints - from lidar

[keith hartley]

I think its where there's good lidar data and imagry for extraction in
selected parts of Canada. The extents are here
https://open.canada.ca/data/en/fgpv_vpgf/7a5cda52-c7df-427f-9ced-26f19a8a64d6
MB, Nova Scotia, Alberta and BC
May want to update the building import project as this is a really good
source!

[Talk-ca] NRC building footprints - from lidar

[keith hartley]

Hi all,
Canadian Geomatics posted this data set a few months back from Natural
Resource Canada.
It's Building footprints from Lidar or high res imagery.
https://canadiangis.com/automatically-extracted-buildings-canadian-open-data.php?fbclid=IwAR22SaWwz7--LarDksVfcQuZ9RDgkVc421n9saJ_Lv8r6xq1qPSrouEF0Ww

>From what I can tell when placing the data over imagery it's very bang on.
Highly accurate, good shapes (unlike the bing files) and well placed. As
far as I can tell no one else has uploaded these to OSM. The areas in
manitoba are mainly where there's little to no other building info.
I can write an upload plan on Manitoba wiki as the data is complaint
license wise. Anything else I should be looking for? The local mappers here
are pretty excited about it.

Re: [Talk-ca] Building Import

[keith hartley]

The patchwork of municipalities is at least useful, before we didn't have a
framework for adding this data, but at least we do now thanks to the
umbrella license @ Stats Canada. We're a big country with very few, but
very skilled OSM mappers (IE gecho111
<https://www.openstreetmap.org/user/gecho111> mapped all of regina's
building footprints! ).

I like the concept of the Bing data, but they may have to do another few
tries, or maybe retain their Neural network. - Is there anywhere where the
Bing data looks nice? I found burbs in Winnipeg not bad, but there's some
really weird elements when the source data is too simple (buildings in the
middle of fields) or too complex (urban cores)

Re: [Talk-ca] Building Import

[keith hartley]

Hi All,
I like the idea of imports, and think there's a lot of value of batch
importing - however we need to run a QA/AC for each. For Manitoba I think
the challenge is getting municipalities to sign on, and move their data to
the canadian open data portal (that is, if they have data or any
geo-spatial information to give ) some information is on the provincial
level, but most of that has already been added to OSM (IE Brandon, Selkirk)
or have been built.

Reviewing some of the Microsoft data, I see a lot of quirks! - IF using it
it's handy to identify buildings, but would REALLY have to watch and review
if importing any of it to osm. I'm not sure about the rest of canada, but
there's "swamp buildings" that some of my collegues have dubbed 1/3 mile
polygons in a featureless field.  Some of the more complex downtown
buildings seem pretty broken, but the data does seem to be decent at
covering suburban areas.

TL/DR version:

I'd be comfortable importing muni stuff (dependent on quality) , but the
Bing footprints would have to be reviewed, nearly on a building by building
level.

Re: [Talk-ca] Talk-ca Digest, Vol 131, Issue 32

[keith hartley]

Woah, leave the list for a week to ski and it explodes!
I'm still sad there's no Manitoba Data (yet)

@John,
Yea, we had pretty good success having highschool students add in
attributes for buildings using walking maps! We concentrated on Wheelchair
accessibility, but ended up adding addresses, and other critical
information. It was handy that Brandon Manitoba already had buildings to
use, but the process could be easily repeated. One issue that you mention
is using street complete, It's a wonderful program, but there's issues with
the students having profiles and privacy. For our purposes with editing
buildings we had Rob create an OSM ID for the students to use.

Re: [Talk-ca] Local groups? Digest, Vol 130, Issue 4

[keith hartley]

I think Canada has some great invested mappers, and resources but we're
pretty far apart! We don't quite have the level of org like the US or
europe has.
As long as we can get the municipality on board with the proper license (IE
OGL 2.0) we can take them on - IE one person did Regina in a matter of days
once it was cleared.

As far as I can tell there's a few of us in Manitoba. I have a small group
that gets together every month to map out something! I know a few mappers
in sask too, but nothing organized.

Re: [Talk-ca] Talk-ca Digest, Vol 129, Issue 38

[keith hartley]

Hi All,
For teaching high school I worked with Rob Langston (who just got the
Canadian geographic award for teachers!)  to find out what would A - be
worth mapping and B- would fit into the curriculum of what they were going
for. We went with mapping out what had wheel chair accessibility for
businesses in Brandon as it didn't require a lot of editing, was valuable
info, and could easily be audited. We tried walking maps, but found it
easier that each student edited 3 business.

I suggested using something like street complete for android, or OSMand for
future edits if we wanted to expand. (or for university students)

Thanks,
Keith

I saw it was a great job. But you're correct, I have no documentation on
how they did it. Licence process, wiki ( I feel Steve already yelling at
his computer)

Hi All,
I found the combo of overpass and qGIS was a really good combo specifically
for this sort of thing. Then you could export into R if you wanted to run
stats (qGIS has a pretty good stats engine too)
All you'd have to enter is the building tag as a search, and it'll return
the results.

The web interface would be even faster for a non-GIS-er and you could dump
it all into a nice .CSV.


There's a few quick tutorials under 10 minutes that should get ya up to
speed.

https://wiki.openstreetmap.org/wiki/Overpass_turbo
and I'm by no means a "Ph. D " in OSM :)

Happy Mapping,
Keith

[Talk-ca] Neelin Highschool OSM mapping

[keith hartley]

Hi OSM List,
Last Friday I worked with one of my colleagues and a high school teacher to
map out some things on openstreetmap with high school students!

To do this we talked about what would work with the high school curriculum,
and with an OSM component. We agreed to look at something with built
environments and some of the limitations people may have accessing them.
This class has some GIS teaching behind them.

Last Wednesday Rob brought in a person from the City of Brandon to talk
about what the city is doing about accessibility. Then he gave the students
an assignment to capture if a building was accessible over the next few
days.

Once they came back on the Friday I did a talk on openstreetmap, some of
the benefits of open data they could use for school work, and how osm is
helping out across the world (HOT mapping, ect). As most of the buildings
were already there we didn't need to add a lot to the map. The students
used the same login (issue with students having their accounts and
privacy)  and used iD editor to add if buildings they looked at were
wheelchair accessible or not. In some cases they building wasn't there, so
I added the basic how to add a building, square it, satellite alignment and
other editing tasks they might use.

In the future we'll probably use field papers to do a larger project (the
field papers server was down that day!) and be a little more ambitious.

I looked over the data later to see if everything made sense and the jokes
were corrected (one student edited the Robs house to be a fish food
restaurant).

Although small, it was pretty successful way of getting secondary students
into mapping with a guided approach.

A secondary added bonus was city of Brandon provided data, however need to
sort out licensing stuff before adding anything to the map.

Cheers,
Keith

Re: [Talk-ca] Talk-ca Digest, Vol 121, Issue 12

[keith hartley]

Thanks for the advice, this might be something well worth pursuing, I can
get building footprints reasonably easily but those extra attributes from a
government are well worth their weight. There's a few governments here that
are interested (sadly the City of Winnipeg won't release their building
footprint file BUT they have released address and tax info ). The smaller
centers tend to be good friends but typically don't have open data portals.
If another government body (stats, city of ottawa ect) could show how
adopting PDDL and CC0, works, and the OSM community (myself or others) can
show the virtues and value of the data we could speed up the process. I
know it's a bit of a bureaucratic nightmare compared to 2010 era (where
there's still stuff on the map from the Manitoba Land Initiative uploads.)
but it could pay out big!

And sorry about the butchering of your name Stewart!

[Talk-ca] Manitoba buildings, addresses and high school work

[keith hartley]

 Hi OSM'ers

I am working on adding buildings to OSM in Manitoba and have a few
questions. I was just offered an updated building footprint and address
shape file from the City of Brandon, and agreement that it can be used in
OSM. I understand that the license needs to be compliant with the OSMs of
course, and will email the licensing group. The City uses a open data
license similar to Ottawa's (can be seen here http://opengov.brandon.ca/
terms.aspx) I can get  written consent in an email if need be as well.
Currently the buildings are from the Manitoba land initiative website (MLI)
and I can see that the city of Brandon Data is much more accurate (in both
attributes and position) I will review the current data. Is there anything
else I should be doing before I upload this?

The plan is to have high school students look at the map and using walking
maps or equivalent data capture (android app) to find what is accessible
for people with mobility issues around their schools. I'll write the
results on a wiki to show our successes. Anyone else have good ideas how to
get students to add to the map? (with teacher oversight of course!)

Cheers,
Keith

That sounds exceptional! How wide range will the building footprints be?
Just wondering on the open portal not inclusive of OSM. Will it be for
certain areas like Ontario only, or the entire country? I have quite a few
colleagues that would be very interested in Manitoba for this!

Re: [Talk-ca] BC2020i and Mapathons with High Schools

[keith hartley]

Hi Jonathan,
I work with a GIS users group in Manitoba (MGUG.ca) and we were talking
about how to use OSM as a learning tool for high school students as well.
>From our education sub-committee we discussed that building footprints or
adding roads doesn't add to what the provincial high school geo subject
curriculum needs. One suggestion was rather then adding new data and
supervising edits, we can augment the map to be more detailed. (better
trails, active transport, or building accessibility for disabled people)

One example  would be addressing mobility and accessibility around the
school. If we could get a few high schools within an area to participate,
we could could add buildings that are accessible via ramps ect, or maybe
signaled crosswalks. That information could show the students issues that
vision impaired, or mobility restricted people face, while at the same time
improving the map. (similar to wheel map https://wheelmap.org)

We're still at the discussion stage, but just a thought!

Thanks,
Keith

Re: [Talk-ca] Talk-ca Digest, Vol 116, Issue 28

[keith hartley]

Hi Everyone and Julia
I'm working with Manitoba GIS users group (or MGUG)  to increase OSM
literacy within our community, and work on HOT tasks as well as help
organize with Building 20/20. We have a number of governmental, private and
educational groups within our user group and I would like to work with them
and the greater OSM community to do this! We can provide data, and
frameworks to help!

I have a talk at our annual large convention Oct 23rd  where I am going to
address the greater membership to find interest. We could help bring a few
university's and high schools that I'm sure would love to assist, as we've
been doing geo-week and GIS day in the past.

I've talked with a few prof's at Assiniboine community college and
University of Winnipeg about Mapping Brandon (they have a great staff) . As
well as our education working group could follow up with high school
students.

We're still organizing but would love to jump at something national!

Keith
