Re: [HOT] How to save 'empty' squares?

[Andrew Buck]

Actually I found your username on the task manager.  There were 16 nodes
that you had added like this that were unconnected and untagged.  An
easy fix.

Re: [HOT] How to save 'empty' squares?

[Andrew Buck]

Also, if you have done this on tasks already you should let us know your
osm username.  Someone can then do a query for all of your work and run
it through the validator to remove these "notes" you left in the
database, since they are not really map data.  This is not difficult to
do, and we won't delete the real mapping you did, just the "fake" notes
that you left in.

And just to clarify for future use, as John mentioned, you don't need to
hit 'save' at all in the editor for a task where you didn't change
anything.  You can just return to the task manager, mark the tile
complete and move on to the next one.

Re: [HOT] an in your spare time project. Cleaning up the imports.

[Andrew Buck]

Replying to my own message to add this...

Instead of adding code to the TM or overpass to change xyz into lat-lon
someone with some apache or other web server experience could set up a
really simple "proxy" service that accepts a url with xyz coords in it
and uses url-rewriting rules to redirect the request through to overpass
with the bbox coords in place of the xyz coords.  I.E. just accept a url
like the following:

http://yourserver.com?query={{bbox_xyz=1,2,3}}restOfQuery...

and do an http redirect to:

http://overpassAPIserver.com?query={{bbox=1.0, 2.0, 1.5, 2.5}}restOfQuery...

I don't know enough about apache to do this myself, but I know it is not
difficult to do with url rewriting.  This way we could put a clickable
link right on the TM using the existing code and have it do an overpass
query specific to that task square.  This would be useful for a lot of
kinds of projects HOT could do, not just this specific one.

Re: [HOT] an in your spare time project. Cleaning up the imports.

[Andrew Buck]

This is an interesting idea, go over the whole continent and do a very
rough QA process.  Only clean up the most egregious problems like vmap0
roads that are only accurate to 1 km; buildings mapped as area=yes; and
a run through the josm validator to get the biggest problems resolved.
(Note that the validator is very picky so getting every validator issue
fixed is probably too much but the bigger ones like untagged ways,
broken multipolygons, etc, would be doable).

Rather than using OSM convert and taking from the extracts we could have
an overpass query embedded into the individual tiles in the TM task.
The TM already has functionality to have a clickable link specific to
each task where you can autofill the correct x-y-z tile numbers for that
specific task.  I don't think overpass supports x-y-z coords for
bounding boxes but it might be possible to have them add that
functionality; either that or add a feature to the TM to allow the
lat-lon bounding box coords to be specified in the URL instead of the
x-y-z coords.  Either one would involve a bit of coding in the
respective project but it would be a pretty minnimal addition to either
project.

Ultimately I think this is a really interesting idea, we just need to
work out the particulars for how exactly to go about it.

[HOT] an in your spare time project. Cleaning up the imports.

[john whelan]

This is not for beginners and its much more something to think about first
before rushing in.

I've been looking over bits of Africa and one thing that stands out is the
large number of imported highways.  Unfortunately they don't always align
to the imagery.  Well they can be within a km or two of where they should
be so they are better than nothing.

Another thing that stands out is the very large number of
highway=unclassified.  I suspect someone with a bit of expertise could
relabel some of these to tertiary.  If we had a few people with local
knowledge we might even be able to confirm that two villages a km apart are
in fact joined by their own private motorway but that is just in passing.

I think it needs a systematic approach to chop the continent up in large
tiles but not downloaded directly from the OSM server but taken from the
daily dumps since we are talking big tiles here.  It can be done by
individual mappers using OSMconvert64 but getting the longitude followed by
the latitude correct is not for the faint of heart.

Because it doesn't fall under an conventional activation for a disaster,
nor does it fall under the mapping for health reasons ie conventional HOT
tasking manger I think it needs a different approach.

I would suggest that one based on the countries with the lowest GDP per
capita get highest priority.  The thinking being that I think there is some
economic value here but it does need to be organised.

[HOT] OpenStreetMap State of the Map International Conference - Help shape the program!

[Blake Girardot HOT/OSM]

Dear Friends,

OpenStreetMap holds a number of regional and country specific "State
of the Map" conferences through out the year.

But, there is also one large, international State of the Map (SotM)
conference each year as well.

The international SotM this year is in Japan and the SotM Working
Group is looking for your input on the speaker/presentation program.

Read all about it here and pick the proposals that you would like to
see (in person, webcast and recorded) at the event:

https://blog.openstreetmap.org/2017/04/11/community-survey-for-the-state-of-the-map-2017-program/

Cheers,
Blake
