Re: [Talk-ca] Osmose, Outil de qualité, maintenant disponible pour le Québec

2013-01-01 Thread Paul Norman 
I’ve been looking at a bot to fix the double-space issue with
CanVec/Geobase, but no idea when I’ll have the time for it so don’t let that
stop anyone else interested from developing one, consulting, etc. Serge’s
work in the US with TIGER name expansions might be helpful.

 

Also, just a reminder, if using a tool like osmose, don’t blindly accept its
suggestions, make sure to review them first.

Osmose is an error detection tool similar to Keepright. It can detect errors
and inconsistencies in OSM data in the form of a map OSM with tooltips. On
the left side, we select from the list of problems detected. On the map, the
select a tooltip and click to edit directly in JOSM.

Starting today, the Osmose tool covers Québec for all error analysis. The
rest of Canada is partially covered for some errors but developers of
OSM-France tell me that there would be opportunity to include all of Canada.
The list of errors is updated daily.

Errors list http://wiki.openstreetmap.org/wiki/Osmose/erreurs

For some errors detected by Osmose, such as abbreviations or Too many
spaces, you will notice when importing in JOSM that the proposed correction
is already done in the Name Tag. When you have completed the correction in
JOSM you click on the Corrected link of the Osmose tooltip to confirm the
correction.

Thanks very much to the developers OSM-France for their excellent work.

The Statistics section allows us to better coordinate, and see if some
adjustments could be corrected automatically by a bot rather than manually.

see error table for Québec
http://beta.osmose.openstreetmap.fr/errors/?country=canada_quebec

As already discussed on the Talk-Ca list, there are a large number of errors
that have appeared consistently in previous Canvec imports. We do not find
these errors in the recent imports. However, we still need to fix the base
OSM for the previous errors.

We find in particular:
lanes = -1
Names abbreviations and with too many spaces

This is an opportunity to make a list of corrections that could be made via
a bot. Are there any developers who have the expertise to run a bot and are
willing to cooperate?

[Talk-ca] Fredericton WMS Offset

2013-01-01 Thread nicholas ingalls 
Hello all,

I've been recently drawing all of the buildings in Fredericton in
preparation for going around and collecting the addresses. I'd noticed that
all the buildings in Fredericton were offset. Naturally I assumed that
the original mappers in Fredericton had done this offset on purpose. I
recently tested this against GPS traces and found that the offset was
incorrect based on the traces I collected. I'm now assuming that this data
was traced from the old Yahoo imagery and current users continue to offset
the Bing WMS to match the data traced from the Yahoo imagery.

I am proposing that we shift the data back to match the Bing WMS and the
gps traces. Does anyone else from the Fredericton area have any comments,
or can explain the offset?

Cheers,
ingalls

Indeed.  Consider all of your available sources.  Part of the fun of
mapping is learning 1) that all of your sources are lying to you, and 2) in
what ways they usually lie.  :-)

So when none of your sources agree perfectly, mappers have to make the best
informed guess that they can make.

Well, I'm glad you asked.  :-)

We've put on a special event because you'll be in town.  You'll be the
guest of honour.  :-)  The regular Mappy Hour will still be held as
scheduled on the 14th.

[Talk-ca] Mappy New Year.

2013-01-01 Thread Richard Weait 
Mappy New Year, mappers.

I'd love to see more Canadian cities start to host monthly OpenStreetMap
events in 2013.  They're a great way to meet other mappers, to learn and
share the experiences of other mappers, to learn about the other things
interesting people do besides mapping.  And they're fun.

It's easy to start and run a local OSM event.  The hardest part is to
actually decide to do it.

Best regards,
Richard
