Re: [OSM-talk] Zoom to search results on the map

[Andrew Buck]

You can hit the "back" button in the browser to go back to the list 
after clicking on one (this is not obviously communicated to the user 
but it does work).  I agree in general though that this part of the site 
is not great UI wise.  Not sure what to do to change it for the better, 
but it definitely could use work.  I guess one improvement would be a 
"back" or "return to search results" kind of button when you click on 
something.  Yes you can use the browser back button to do this now, but 
there is no conveyance in the UI that this is an option.  Adding an 
explicit button would go a long way on the usability front.

This removes the search results and displays details of the object you

enter the search parameters again and nominatim now searches from the 
last point the map was centred at. So the search results differ from the 
first try. Now you have to remember what results you've looked at so you 
don't look at them again.


Is there no way to show the second, third, etc, result on the map

Re: [OSM-talk] GeoChat

[Andrew Buck]

It is a great little tool.  Simple, but surprisingly effective. It 
actually works amazingly well when coupled with a voice chat program.  
In HOT we use mumble for voice and the geochat plugin combined with that 
allows mappers to "point" to objects in imagery by centering on them and 
then letting other user look at the same area to discuss what is being 
seen in the imagery.  Things like how a road should be classified, how 
to tag a specific thing, etc.  Of course you can use the text chat right 
in the plugin as well, but I always prefer voice chat for discussion as 
it is just so much faster.



In any case, it is not a plugin I use super often, but when I do need 
it, it is just the right tool for the job.  My only suggestion would be 
that you consider making "show users on map" default to "on" instead of 
"off" like it is now.  I always forget to turn it on unless I 
specifically want to collaborate with someone, but I think if it 
defaulted to on then it would get a lot more use.  It would be really 
fun to be mapping and see other people showing up in the area to see 
what you are working on.  I think it would really add to the sense of 
community in OSM.

Sorry Paul, that was caused by forcing https on all OSM servers. Java,

updated the URL in the plugin and tested that it works.

Re: [OSM-talk] How to map alleys in African cities?

[Andrew Buck]

Pierre's suggestions are a good guideline in general and I don't have
any disagreements with them.

I did, however want to expand a bit on the idea of when to use service
roads, so here is that...

I for one am in favor of additionally making liberal (but careful) use
of highway=service.

A service road is like a residential road, but is not meant to be used
for "through traffic" but rather as the first or last leg of a longer
journey.  With this in mind, I offer up the following example as a good
guideline (or case study) of how this should look in practice:

Several years ago, I traced the roads in Ibadan, Nigeria.  It was nearly
a blank map when I started so I had complete freedom in deciding how to
classify them (this was years before "highway tag africa").  I started
by just marking nearly everything as highway=residential.  Then after
the whole city was mapped I spend some time just looking at the finished
map and the roads overlaid on the satellite imagery.  After taking in
this "whole city view" for a while I began to see patterns in how the
roads were laid out, and these patterns suggested which roads should be
downgraded to service.

In the case of Ibadan there are little "pocket communities" of people,
separated by streams with a few roads crossing the streams but a dense
network within each community.  So after digesting the map, and seeing
how the town was structured, I decided I would downgrade all the roads
that only served to access buildings within one community, but were not
part of the routing if you were traveling outside of the community.
This lead to a marked improvement in the quality of the map, which you
can see in the two links below.  Although I finished tracing all the
roads, I didn't finish all the classifications, so you can see a good
"before and after" of how much better it looks with proper use of
service roads.

Here is a "before" section where all the roads are left as residential:

  https://www.openstreetmap.org/#map=15/7.3354/3.9118

And here is an "after" section where I have downgraded local-access-only
roads to service but left the rest as residential.  Notice how much more
clearly you can see the neighborhoods, and also how much easier it is to
follow a route, without having to use a route planning tool.  You can
navigate just by looking at the map.

  https://www.openstreetmap.org/#map=15/7.3933/3.9598

In the second example above you can actually see some areas of all
residential to the east, so there is a very clear difference between the
two sections.

Obviously every town will be slightly different, but I think this is the
general rule we should follow:

   if you use the road mainly for accessing buildings (even if it is
   a fairly large number of them) but not for long distance travel,
   then the road should be downgraded to service.

After you spend a bit of time looking at the whole town, and keeping
this rule in mind, you will get a good sense of what to downgrade.  Then
it is just a matter of going through and applying it.

Anyway, hope this all makes sense to people.  I had been meaning to
write it up for a while now and this seemed like a good opportunity.
Maybe I will try to go through and finish up Ibadan, I am a lot faster
at this now than I was back then, so it wouldn't take me long.  I will
leave it for the time being so it doesn't break the examples.  If people
think this sounds reasonable, maybe we should grab some before and after
screenshots for the wiki to document this.

Re: [OSM-talk] Odd mapping in Atar Mauritania

If it is an untagged way that covers the whole block of buildings I
would say just delete it.  It is not accurate data anyway, so not really
worth keeping.  I know we try very hard to clean up data from newbies,
but this I think is beyond the point where it makes sense to.

Re: [OSM-talk] Find missing roads

A very good plugin.  I have added a couple roads I knew had been
constructed since the Bing imagery but I haven't had a chance to
survey yet since they are a long ways away and I only have a bike for
transport.

I would suggest that you make your filtering algorithm a bit less
"picky" though, since every road around here shown as missing is only
detected for a portion of it, and for the remainder I had to fill in
the gaps based on other clues in the Bing imagery and whatnot.

Other than that though a great tool though, glad to see this kind of
"closing the loop" between OSM data consumers and us mappers.  Keep up
the good work.

For an african city example you could use Zliten, Libya.

https://www.openstreetmap.org/#map=12/32.46/14.5587

I marked the surface=* values there from satellite imagery there a
couple years back as part of the HOT activation during the civil war
there.  The core of the city is paved and the outer portion is all
unpaved, with the main roads going in and out of the city being paved
as well.  Everything in the city and the surrounding area should have
a surface tag on it, as I systematically checked them using the
'Surface data entry' paint style in JOSM.

We have also been doing a lot of tracing in West Africa (specifically
Liberia and Sierra Leone with a bit in Guinea).  These roads are not
all tagged with surface values though other than a few isolated
pockets.  We had been wanting to do better surface data though so if
you message the HOT mailing list with a request for a specific area in
one of these countries we could try to add the surface tags for you.
Just browse around and see where you think it would make sense and let
us know.  Can't guarantee we will get it done for you, but like I said
we did want to get more surfaces tagged anyway and this way we could
kill two birds with one stone.

Re: [OSM-talk] Release openstreetmap-carto v2.28.0

[Andrew Buck]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

There seemed to be a time yesterday when residential roads weren't
being shown at some zoom levels.  I started drafting an email about
this (I actually like some aspects of that change but wanted to add
some comments to improve the design further).  However this morning
when I went to double check some specifics regarding zoom levels I
noticed they are back again.  Was this just a mistake in the
stylesheet that then got switched back?

And in either case, I think this is an issue that could merit some
discussion.  For example we introduce different road types like
primary and trunk progressively, but then throw in tertiary and
residential at the same zoom level and don't differentiate them until
the next zoom level in.  This seems like a major area for improvement
since roads are such a prominent feature on the map and most urban
areas are very cluttered due to this design choice.

There have been a lot of really interesting changes to the look of the
map recently and I am glad to see that it is evolving again now that
the switch to Carto has been finished up and new changes are being
worked on again.  I wanted to say thank you to those who have put in
all the work on these changes and I hope to see more as the project
progresses.

-BEGIN PGP SIGNED MESSAGE-

This is a very nice little guide.  It would be a shame to lose this
after the activation is over as the Hagupit page is unlikely to get
much traffic once the activation ends.  For that reason, it would be
good to get this included on on the main PH page or somewhere like
that.  To make maintaining it in multiple locations easier, you could
convert it to a template and then link the template on both pages (and
any others that might be relevant.

Re: [OSM-talk] JOSM Imagery Contrast

Josm has a trac system on the josm website where you can submit
tickets for feature requests and whatnot.  For the specific imagery
contrast patch though PovAddict wrote that himself but it was not a
good enough quality patch to be implement in josm itself.  It had a
memory leak for example that would eat up your memory over time
forcing you to periodically restart josm.  The best thing to do would
be to talk to PovAddict on IRC (he is usually on #osm) and see if he
would be interested in refining it.

Yes, in a case like the sidewalk separating them as a barrier though,
you can simply add a noexit=yes on the road end.  All major error
checkers override the warning when this is present.

I think this is the obvious solution and am surprised this thread has
gone on this long.  A simple mistake was made, it was found and
corrected, and people will be more careful in the future.  This is how
OSM works, why are we still discussing this?

 +0.95 (because grass is really not a landuse but a landcover), or
 a fence, or guard rail or retaining wall or wall, or waterway, or
 bollard, or  As soon as you micromap the stuff between the
 unconnected roads it should become clear that they aren't
 connected. In some rare cases there might be something that is hard
 to map, e.g. a sidewalk separating the two roads (in my area often
 with parked cars preventing also physically the connection for
 cars), which still could be abstracted as a footway connection.

[OSM-talk] Proposed mechanical edit to convert alt_name tags

[Andrew Buck]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello everyone.  Recently HOT has been responding to the ebola
outbreak in western Africa (specifically the countries of Guinea,
Liberia, and Sierra Leone).  As a part of this response we have
converted the GNS name files containing populated place names from
their original csv format to OSM format using a python script.  The
files have then been broken into tiles corresponding to task manager
tasks and are being manually checked against imagery, topo maps, and
existing OSM data before being finally merged into OSM one by one.
The task manager jobs are being carried out by a hand-picked team of
people using private task manager jobs so that the work is done
carefully and no one just blindly dumps a load of data in without
first checking it.

However, since the conversion scripts have changed over time and since
some work was done manually by others, we ended up using two slightly
different forms for the alt_name field in the case where there are
more than one alt_name for a given place.  Some use the form
alt_name_2 and some use alt_name:2 (with the 2 extending to higher
numbers as well, some of these places have as many as 6 or 7 alt_name
entries).

After consultation with twain47 regarding which format would be
preferred for nominatim, it was decided that the alt_name_2 was the
preferred format (the :2 format gets confused with the language
variants, so the underscore version is preferable).  Twain47 has
already written a patch for nominatim to make this work, and the pull
request and push to the live server is pending.  Once the new code is
in place and shown to be working, my plan was to do a mechanical edit
to convert all of the existing alt_name:N tags to their corresponding
alt_name_N equivalents.  There are also a few similar variants like
alt_name2 which would be converted at the same time.  All in all it
looks like about 500 or so objects worldwide are tagged using one form
or another of the deprecated formats.

I can either limit this conversion to the areas where HOT has been
doing this kind of work, or I could extend it worldwide.  My suspicion
is that after the ones from the HOT areas have been converted there
will likely be only a few elsewhere anyway, so it probably makes sense
to just do them worldwide anyway.

Are there any objections, or suggestions on how to do this better?
And finally, if it is decided to carry out this action, is there
someone who would be willing to actually carry out the change
themselves with a mechanical edit account or bot or something, or
should I do it myself in josm?

Thank you for your consideration in this matter, and I would ask that
we try to expedite the discussion on this (assuming no major
objections are raised) as there are external organizations using our
data to respond to the ebola epidemic, and the quicker this can be
sorted out the less painful it will be for them.

Re: [OSM-talk] tag with value lists Was: Proposed mechanical edit to convert alt_name tags

 Isnt the semicolon the list seperator typically used in OSM? My 
 intuitive answer would have been alt_name=a;b;c;d
 
 Flo

My understanding was that since almost nothing actually understands
the ; separator that doing it as multiple tags is the preferred
system.  I think the ; separator is not really understood by
nominatim, for example, whereas the multiple tags system is.  I think
nominatim might work with ; in a sort of hacky way since it probably
will match on substrings, but it will confuse other parts of the
system, not to mention all of the other systems that don't understand ;

In any case I don't really want to turn this into a discussion of how
multiple values should be handled in general as this has been done
before and no one has come to a solution.  That is a discussion for a
different time and place, this is just about remedying a minor
inconsistency in the current tagging.

 Hi,
 
 I think using alt_name:1 was not the greatest idea at the time.
 
 So you have a
 
 hand-picked team of people using private task manager jobs so
 that the work is done carefully and no one just blindly dumps a
 load of data in without first checking it.
 
 but you can't be bothered to discuss with the wider OSM community
 how to best address the multiple alternative name issue; instead
 you pick something that works by accident.
 
 Then you plan to make it right by using the unprecedented and 
 illogical scheme of alt_name_x, and before you discuss the issue 
 with people who might help you devise a better way, you ask the 
 Nominatim maintainer to add a quick patch for you.

Yes, we are using what GNS has for the various alt_name entries.  We
are checking each place name against 3 different sets of topographic
maps and have seen some of these spelling variants on the various maps
and when we do see them they agree nicely.  Additionally, the alt_name
variants have proved to be used in various places like news reports
and field reports from medical workers in the area so they seem to be
good data, at least as far as we can tell.  The scheme is not
unprecedented, it was already in use in the database (which is why we
adopted it) and I don't see how it is illogical, it seems like the
obvious thing to me.

 alt_name_x sounds like a bad idea to me as well - why is there an 
 alt_name_x but no old_name_x or official_name_x for when something
 has two old names or two official names? The patch that has been
 suggested for osm2pgsql
 
 https://github.com/openstreetmap/osm2pgsql/commit/29ccee0859fa4728378d7299e9deeab737da347d

  simply accepts alt_name_whateversomething but doesn't afford the
 same to other name tags. Is this matter really so urgent that we
 have no time to think it through?

I would suspect that it just hasn't come up for old_name and such.  I
am sure there are cases of this but since there aren't that many
old_name's to begin with there probably just hasn't been much of a
need for it.  A similar patch for the others might make sense if they
are used, but I just don't think it has been an issue so far.  Looking
at taginfo shows 31 old_name_2 and 39 old_name:2 so it is there but
not enough to have encountered problems due to how rarely it exists,
hence no patch for it so far.  If we want to discuss those as well
(and consolidating them in a similar fashion) then I am fine with
that, but for expediency's sake I would like to get these sorted out
so they are consistent first.

 (with the 2 extending to higher numbers as well, some of these 
 places have as many as 6 or 7 alt_name entries).
 
 Do the people who carefully add the data have the knowledge to
 assert whether keeping these 6 or 7 names really adds value, or are
 they instructed to simply copy whatever GNIS has?3

As I outlined above, we are keeping them as they are; they seem to be
in good agreement anytime we are able to check them so there is no
reason to be distrustful of the ones we don't have alternate sources for.

 Thank you for your consideration in this matter, and I would ask 
 that we try to expedite the discussion on this
 
 Missing - or expedited - discussion has got you into this
 situation. You're now trying to introduce a badly thought out
 schema on the quick; a change to our instance of Nominatim would
 make things worse by actually encouraging people to use this.
 
 I am very unhappy with the whole process and I can only hope it's
 the exception not the rule.

It has been discussed in great detail just not on the global mailing
lists.  I am sorry we made a small mistake regarding the tag fields,
but we have caught it now and are trying to correct it.

 I think using a semicolon-delimited list is better than a
 potentially open-ended set of keys such as alt_name_x, and
 already has precedent. While it is true that semicolon as a
 multi-value separator is not written as a law of OSM tagging, it
 is quite frequent enough to be a de facto tagging guideline.
 

Both systems are in use and were in use before we started working on
this GNS stuff.  The tiger tags are one example, but there were
alt_name_N tags before we started as well.  If you want to have a
discussion about changing all of these worldwide, that is fine, but
this thread is about fixing the alt_name:2 ones.

Please either weigh in on that, or keep silent.  I do not have time to
have a general discussion about broader topics of how multi-valued
keys should be handled.  There have been dozens of threads that
discussed that and no one has ever come up with a good solution, so I
am not going to have this thread get dragged into the same discussion
that has been had many times before.

There has been one person who has said it makes sense to change them,
and all of the other posts have been about discussion of other topics.
 So unless someone has some concrete reason _not_ to convert the few
mistaken ones, I will go ahead and do that.  We can have these other
discussions some other time when people are not waiting on the results.

This is a really cool site.  Many thanks to the people at the State
Department who put this together.  The video tutorials for how to
register and edit are an excellent introduction for new mappers.  THey
also have a nice short written guide for each step as well.

It would be good to make use of these videos in the HOT learning
guide.  It is also possible to add subtitles to these videos in
different langauges, it would be interesting to subtitle them in the
languages for the countries we are working in.  There are websites
that let you add a wrapper around youtube other online videos and then
the community can just submit subtitles in different languages easily,
we used them on a different open source project I worked on in the past.

See below for the original message posted to the talk-ph mailing list.
 I replied to that message and also forwarded this reply to the HOT
mailing list as well.

There is a lot of Bing imagery covering the area so spotting landing

Also, I am on mumble now, it would be good to get everyone on there to

Re: [talk-ph] Tombs as buildings?

[Andrew Buck]

-BEGIN PGP SIGNED MESSAGE-

I noticed a couple of these as well, although nothing quite so
extensive.  My suggestion would be to not delete them but to tag them
as something more appropriate.  Something like building=mausoleum
might be appropriate but maybe something that is not a building=* tag
would be better to prevent problems with people trying to count
buildings in an area to get population estimates.  Most people just do
building=* in their analysis which works pretty well, but things like
this could throw that calculation off.

If some Philippines residents could have a look at these areas and
confirm that these really are mausoleums and then look into how best
to tag them that would be cool.  I am a bit hesitant to do it myself
as I am less familiar with this stuff than the locals would be; we
bury people underground here almost exclusively, so our cemeteries are
very different from the ones in the Philippines.

Re: [talk-ph] Mountains and elevations removed at Biliran

Ervin,

Someone from IRC asked me about removing them I said to just leave
them but someone else may have removed them as well.  OSM is not
really the place for contour lines though, other than the node at the
peak of the mountain.  I would not recommend adding them back in.  If
you want to map elevation contours the thing to do would be to run
your own OSM server and create the lines on there.  I have thought
about creating such a server but I do not have a computer to host it
on, etc.

Totor,

The best thing to do with these kind of issues is after the people
have stopped working in the area, just have 1 single person download
the whole area and look through it.  Even for a very large city like
Tacloban, you can look over the whole thing in a couple of hours
(assuming everything is done).  Filling in the missing bits and double
checking the tagging is a very useful thing to do.  For anyone
interested in seeing how to do this I can show you via skype
screenshare, contact me at andrewbuck40 on skype if you are interested.

The short version of how to do this, is use either the mirrored
download plugin for josm to download the area or for smaller towns
just a normal api download or two will be enough.  Then enable the
typhoon josm paint style available on the wiki so you can see the
building damage tags.

 Hi,
 
 On the hotosm tasks I participated in (342 and 347 mainly), I

 * I think a clearer Unlock it!. button might help for those who
 want to stop and only see the Mark Task as Done button. * For new
 tasks, the introduction and workflow could maybe add a note to only
 click Done if you are 100% sure ALL has been traced. * It seems
 impossible to invalidate a tile that is already validated.
 
 Another solution could be to restart a new task for the same area
 once the initial one is validated to check for missed parts. Task
 360 kind of does this, but mixes adding lacking buildings and
 evaluating damage. This seems logical, but the result is that some
 mark a task as done just after adding the buildings, and some omly
 after assessing the damage (without adding new buildings).
 
 I'm not complaining ! It is really great to see so many persons
 involved, and I'm sure it is very helpful. The problems mentionned
 above are really small compared to the benefits.
 
 Happy mapping, and thanks to all.

It has been removed from the Featured tasks list but there is really

Re: [talk-ph] [HOT] Typhoon Haiyan Mapping Progress

[Andrew Buck]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I agree that wider coverage will be needed and I had hoped that by now
we would have a better indication of where to map as well.  My reason
for staying with Tacloban for so long was largely due to lack of
knowing where else to shift focus to (although I did allude to this a
bit by suggesting the other villages on the coast northeast of
Tacloban), more importantly due to a second fact...

When we map an area, it is only really useful for us to map areas that
the aid organizations we work with will be responding to.  For the aid
organizations that don't know about, or don't know how to use, our
map; then no matter how good the coverage is, it doesn't help them.
This is the main reason I chose to focus on Tacloban.  It is badly hit
(as were many other places as you rightly point out) but it is also a
provincial capital, and it is the largest town in the immediate area.
 Because of this I figured that most of the international response
would likely be directed there, and since it is mostly the
international orgs that we tend to work with I figured the map data
would be most useful there.

Now, that being said I want to make it clear that the explanation
above is not necessarily an argument for continuing to focus entirely
on Tacloban, just merely an explanation of why I hadn't directed
people elsewhere yet.  I agree that we will need to spread out our
efforts at some point, and that point may be approaching, the question
is where to focus next.  As I mentioned previously, I think the
villages along the coast to the northeast will be hard hit (and due to
their proximity to Tacloban will likely receive international aid).
There are also villages along the coast to the south of Tacloban that
will have been hit hard as well since the eye passed directly over
them.  The eye track will likely have done the most damage, or the
area to the north of the eye track since the storm rotates
counterclockwise as it moves westward.

If anyone has better suggestions of where to spread out to I am
certainly open to them.  Like I said I am not saying we need to stay
at Tacloban (and the surrounding area) just explaining why I was
continuing focus there.  I know the storm affected a lot to the west
as well but I figured this would be trickier to map for two reasons.
1) it is a larger area with not such and obvious target for
international aid, and 2) the wind speeds were lower to the west due
to the storm being disrupted by the islands.  As for the idea of
mapping the area affected by the earthquake to the south, my
understanding (and this could be wrong) was that most of what we could
do remotely has already been done when the earthquake hit.

So that is all of my reasoning at the current time for our current
focus.  I hope to begin hearing more concrete info from aid orgs today
so I might redirect people when I hear from them, but for now my
advice would be to try to continue with Tacloban (especially the low
lying areas) and simultaneously spread out into the surrounding
villages until/unless we get something concrete from an aid org.

 Hi,
 
 According to Al Jazeera, the death toll could be very high, sadly.
 And several millions of people have been affected.
 
 I'd like to remind that an often-mentioned weakness of OSM is the
 uneven quality of the coverage, and that it is not because you have
 a hammer that everything is a nail.
 
 So, while Tacloban was indeed hit very badly, and a detailed
 building map there is undoubtedly useful, it might also be useful
 if some of the mappers who wish to contribute took a broader view,
 to map, for example, some of the roads and villages that are
 visible on (sometimes recent) high resolution Bing imagery 
 (http://osmph.github.io/Imagery_Coverage_Map/), but sometimes
 still unmapped in OSM. (Not to mention the rivers).
 
 GNS (http://wiki.openstreetmap.org/wiki/GNS) can also be a good
 source for names, even if it sometimes includes old versions of
 duplicated nodes with inaccurate location. High resolution imagery
 can be useful to tell which is right in these cases.
 
 Best wishes,

[talk-ph] Typhoon Haiyan Mapping Progress

[Andrew Buck]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I am happy to report that we have been getting a great response to the
Tacloban tracing task to respond to typhoon Haiyan.  The task manager
has been very busy, and we are just passing the 24 hour mark since the
job was first set up.  So far there have been 33 people who have
marked at least one tile complete (no doubt a few more worked in the
area but didn't finish their tile and we welcome these changes, too).
 Collectively we have mapped just over 10,000 buildings which by my
very rough estimate is something like 25% of the buildings in the city
(although it is hard to make a good estimate since the city is so
varied from one place to another).

Although the storm affected a very wide area and we will likely
receive more detailed requests from aid organizations in the days that
follow, the initial idea of focusing on Tacloban seems to have been
correct as the eye of the storm passed just south of there (since the
storm traveled westward, areas to the north of the eye will get
slightly more wind damage than areas to the south of the eyewall).  No
thorough damage assessments have been carried out yet as the storm has
just passed the area a few hours ago, but already we know that there
was significant wind damage to the city, as well as major flooding
from the storm surge driven by the hurricane.  Initial estimates
indicate that when it made landfall, this typhoon had higher
windspeeds than any recorded typhoon in history (at the point of
landfall), with sustained winds in excess of 190 mph.

Thank you to all who have contributed so far and are continuing to
respond to this request.  We are beginning to hear from aid
organizations that they are planning various responses and when we get
more concrete information from them on where our efforts can be best
directed details will be posted here.  Not only will your work help
them in this case, but the area will be that much more prepared when
the next storm hits this area (this is after all, the 25th major storm
to hit the Philippines just this year).

I loaded GPS tracks in the area and the imagery looks to be aligned
very well (as is typical of almost all of the newer Bing imagery, they
seem to have improved their process in the last year or so).  I assume
the mis-aligned data in the area is probably taken from older imagery
that was not aligned well.

startup that doesn't have signs, etc, in place yet or what the deal is.

I don't see any harm in leaving the node there for now, but it would
be worth either following up later with them to confirm whether they
actually took over the building, or what the deal is.

Re: [Talk-ca] Kelowna Open Data

[Andrew Buck]

Paul,

I am working with some people who live in Kelowna doing some remote mapping
to trace buildings in the city of Kelowna and elsewhere.  I have asked them
what they think about the import and they think it sounds good.  The have
done a bit of mapping but not a lot themselves, so I don't know how
representative they are of the local mapping community, but there is at
least interest from their perspective.

I would be willing to help merging in the import on the buildings I have
traced in already.  If you could prepare the files for import I will help
with the merging/conflation process.

Re: [Talk-ht] [HOT] OpenStreetMap HOT's work in Haiti featured as Editor's Pick in Medium.com today

[Andrew Buck]

That is a very well written article.  Thanks for sharing it.  Not sure if
HOT has a 'media coverage' page, but if it does, this is one that should go
on there.

Re: [Talk-ca] Advice on Addressing

[Andrew Buck]

Individual buildings is definitely preferable to interpolation ways.  For
adding address coverage in Fargo, ND, I used the 'audio mapping' technique
detailed on the wiki while riding my bike up one sidewalk and then down the
other on each street.  It goes very fast and works very well.  I also
gather building:levels data at the same time as well as whether the address
is for a house or apartment building.  So my audio recording sounds like...

Number 102 is a 1 storey house, number 104 is a 2 storey apartment, etc...

Hope this helps.

Re: [Talk-ca] Fredericton WMS Offset

[Andrew Buck]

Hi,

I am not from the area, but I did want to post my 2 cents about this
issue.  Your idea of how the offset got started sounds correct.  I
would caution you though that GPS traces can be offset, too, due to
atmospheric effects.  To really get a good trace with no offset you
need to do a few traces on different days of the same road (or path is
better since it is narrow) and through an area with few buildings
around as these can cause offsets, too.

Other than those issues, if you trust your traces then I see no reason
not to fix the offset, but as I said make sure your traces are good
first.

[Talk-ca] Proposed mechanical edits: GeoBase/CanVec Service Surface and GeoBase/CanVec name spaces

[Andrew Buck]

The easiest way to fix this may just be with a text editor and
xapi/overpass queries.  First do a query to get a file of affected objects
in a given area, then load the area in a text editor and do a search for
the double space.  Jumping the search ahead should take you not only to the
given object like josm would but should position your cursor right on the
affected spot.  This way you can check that you are not breaking anything
before correcting the space and moving on.  Alternatively the search and
replace mechanism in the editor could be used, either manually or if we
know for sure it is acceptable to do, a replace all.

I tried doing a taginfo query to find out how many objects were affected
but couldn't figure out a syntax to work correctly.  If anyone knows how
many objects are affected by this that would help in determining whether
manually checking each one is feasible, or whether it would be better to
just fix them en-masse and try to clean up mistakes afterwards.
