[OSM-talk] OpenStreetMap Carto database schema change

[Paul Norman]

One of the long-running OpenStreetMap Carto projects has been a database 
schema change, 
https://github.com/gravitystorm/openstreetmap-carto/pull/2533. Included 
in this are


- database schema change;

- disjoint area handling;

- different tag columns; and

- multipolygon handling changes

This is now in a state where the output would benefit from review, not 
just the code, and I have set up a demo at 
https://lua.osm-carto.paulnorman.ca/. Please read the issue and provide 
feedback on Github.


Feedback is especially needed from people who deploy OpenStreetMap 
Carto, as the database schema change requires a database reload. To 
allow people to switch over, cartographic compatibility between the 3.x 
and 4.x series will be maintained for some time. The time has not yet 
been determined.

Re: [OSM-talk] Untagged Nodes and Ways

[john whelan]

I seem to recall that JOSM allows you to pick and choose what to validate
both for what is in JOSM and what should be validated on uploading.

It's quite useful in that you can just validate for duplicate ways or
select highway=whatever then check for crossing ways.

If you're mapping in Africa the highway wiki recommends tagging path rather
than footway.  Apparently the locals use small motorcycles on them.

[Andreas Vilén]

The Josm validator doesn't always work. I have noticed untagged ways uploaded 
by myself long after I created them, and I wouldn't miss a message like that.

Often it's footways where I've drawn a lot, tagged them in bulk and missed a 
few.

untagged ways as member of a relation were not included in the count. There
are over 7M untagged ways that are part of a relation.

My guess is that people started to add in a feature but somehow forgot to
tag them before uploading. JOSM gives a nice warning, which I've received.
iD gives a warning as well but not as a new dialog box that you have to say
yes go ahead and upload.

Re: [OSM-talk] adding Wikimedia videos to OpenStreetMap objects

[François Lacombe]

Hi Oleksiy,

It'e surely useful to link OSM objects and wikimedia content.

As you mentionned, OSM objects can easilly be linked to wikidata with a
simple scalar value.
Since wikimedia video can also refer to wikidata object, a link between OSM
and video sounds redundent.

Such a link shouldn't be done as to ensure of data quality and its
maintenance


All the best

Francois

some days, max some weeks. If you can make some sense by adding a pertinent
tag (in an area you know) you should do it right away of course, but if you
find some long untagged way which seems to have been a lot of work to add
it, I'd rather be conservative before deleting it, e.g. contact the
original author or add some tags to it.

I think a hint like JOSM presents you when you try to upload an untagged
way or node (that aren't part of a relation either) should be sufficient. I
wouldn't reject those ways by the api. There might also be some sense in
this, e.g. when working on big things a mapper might want to upload part of
his work before it is finished, to continue work on it later.

The once-and-for-all solution would be a full history DB schema from which

I don't have a pointer handy but there has been some work done on

You could mitigate that in the future by making a copy of the current 
tileset at a fixed point (1st of january for example).


But I agree that it would need quite some space for a gimmick. But with 
Seagate announcing 16TB drives and prices of drives dropping steadily, I

Re: [OSM-talk] OpenStreetCam plugin

[Rod Bera]

Hi Martijn,

When trying to install the plugin I get a message saying
that downloading failed, with
"
error message javax.net.ssl.SSLHandshakeException

java.security.cert.CertificateException :
no suject alternative DNS name matching www.developper.skobbler.com found
"

and I am asked to restart to have some change effected...

When I restart I get the message:

"
could not load plugin
because main class
org.openstreetmap.josm.plugins.openstreetcam.OpenStreetCamPlugin was not
found
"

Seems it's nothing to do with the plugin itself, but more likely with
the way it is made available.


On a different note: an overall improvement to josm would be to make the
content of message pop-up windows copy-paste-able. This would save time.

Rod

Re: [OSM-talk] OSM then and now revived

[Simon Poole]

I suspect the main problem is that in 2007 we didn't really have a lot
of data so rendering tiles or it is really not such a big issue. However
2010 and later would require per point in time a rather largish
rendering DB plus space for tiles a model that neither scales nor would
seem to be a particular good use of resources.

Well, to be pedantically correct*, many untagged ways are members of
relations which have tags.

* The best kind of correct

Re: [OSM-talk] OSM then and now revived

[Martijn van Exel]

My poor little tile server machine doesn’t have the storage for that, but it 
would sure be cool to set this up for more points in time. The server itself is 
not hard to get up and running, although I did find the instructions on 
switch2osm to be out of date. I followed the instructions here: 
https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04 
.
 The only extra step was to download osmosis 0.35 and convert the 0.5 planet to 
0.6. For older planets you’d need to come up with a way to convert 0.3 / 0.4 
planets to 0.6. There is a script to convert from 0.4 to 0.5 but I don’t know 
of anything that can handle 0.3 planets.

Re: [OSM-talk] OpenStreetCam plugin

[Martijn van Exel]

Rod — what if any messages do you get, or how does it fail? I don’t think we 
are at version 42 yet — OpenStreetCam plugin release is version 32, the 
deprecated OpenStreetView plugin is version 31.

Anyone else experiencing problems with installing it?

[OSM-talk] adding Wikimedia videos to OpenStreetMap objects

[Oleksiy Muzalyev]

Dear fellow mappers,

It is possible now to upload to the Wikimedia Commons the videos which 
illustrate Wikipedia articles. On Saturday I went to the highest summit 
of the Swiss portion of the Jura mountains, Mont Tendre 
 , and filmed a short, 4 
minutes, video about it.


Then I added this video to the respective Wikimedia category and to the 
Wikidata page, and added wikidata=* and wikimedia commons=* tags to the 
OSM node of the summit: http://www.openstreetmap.org/node/343335042


I used for filming the cameras Sony RX100 V and DJI Osmo, and for the 
aerial footage the latest DJI Phantom 4 Pro+ quad-copter. The Wikimedia 
accepts videos in the free open WEBM format, so I converted the MP4 file 
into WEBM with the ffmpeg  command line tool.


The quality of the resulting WEBM video:

https://commons.wikimedia.org/wiki/File:Mont_Tendre_Jura.webm (select at 
least 1080P resolution in the player for viewing)


is comparable with its Youtube version:

https://youtu.be/pgNiCYzr7sg

The DJI Phantom 4 Pro+ has got a camera with one inch image sensor and 
improved lenses. In my opinion, it is the first aircraft of this class 
capable to film really useful aerial photos and 4K aerial videos. 
Creating a good video is not a trivial task, still there is a lot of 
information on it, and the quality equipment is readily available.


And it is kind of interesting. In fact, we could climb on the Mont 
Tendre only from the third attempt. Two first attempts failed due to the 
snow, wind, low outside temperature, and the remoteness of a location 
(it is also the most isolated mountain of the canton of Vaud), besides 
we had to carry the equipment. Probably, I would never did it in winter, 
if it were not for filming.


A video may convey much of significant information about a location. It 
may provide not only ground and aerial footage, but also some practical 
advice and insights via a microphone. Perhaps, in future we may think 
about creating a video=* key for direct linking to the videos with a 
Creative Commons license. But even now it is possible to do it via 
wikidata=* and wikimedia_commons=*.


With best regards,

Oleksiy
