I really appreciate your work and the work of all contributors. So
excuse me if I'm little bit too harsh now.
I'm trying to to collect the minimal common set of HOT tags for
specifying a renderer, for future use and for OSM quality in general.
Will already answered finally in an earlier post (thanks!) - but I'm
sorry to say: What we (OSM) now have in HOT pages is a tag mess since
years!
Please correct me if I'm wrong. Perhaps there a process on tagging
mailing list I'm missing? Here's what I found:
To me the potential main HOT tag page is "Humanitarian_OSM_Tags" [1].
This page is very "orphaned" - it has been edited twice since 2013(!?).
It prominently points to "Humanitarian_Data_Background" as "An
up-to-date list of tags for HOT" - being a page which has been updated
3.5 years ago (!?).
Then I see that no single wiki page with Nepal in its title - including
"2015_Nepal_earthquake" [3] - is pointing to Humanitarian_OSM_Tags,
whereas the Nepal_remote_mapping_guide [4] mainly lists the usual main
tags (like building=yes, natural=wood|water, water=*, waterway=river,
waterway=stream, landuse=farmland).
I would expect at least to see tags like damage:event and idp:camp_site
- being top 20 in [6] - to show up in any wiki page related to tags
mentioned above.
But these aren't even mentioned in the wiki except somehow in [4] - but
which was declared outdated 2013.
How can we clean up this under-documented mess and "tag soup" at least
for a small common set of tags?
Yours, S.

This OSM response for Nepal is quite challenging. And even more
difficult for our friends at the Kathmandu Living Labs (KLL) who
have to suffer the emotional impact of the second earthquake this
week. They also have to move from the famous Yellow house to a
school. This should assure them a more secure area to work.
Cheers to them that maintain the Nepal earthquake Ushahidi map,
provide various mapping services to the humanitarian in the field
and assure the interface with the Nepal governement and the various
UN Coordination structures for this response (ie The clusters to
coordinate sanitation, water, logistic, food distribution, health,
etc).
As usual, the Humanitarian OpenStreetMap community assures the
interface between the OSM community, the UN agencies and the
international organizations. We support the OSM remote response from
around the word and we co-coordinate with KLL. We both interface
with the DHNetwork digital organization and various other groups via
Skype. We have a great support from the International Charter
(imagery providers), UNOSAT, DigitalGlobe, Airbus, the HIU unit of
the US State dept., Google, and our dedicated OSM/HOT experienced
contributors and developpers.
Plus the various groups that provide the 30 minutes updates for the
various OSM exports.

Still more challenges to come with the landslides risks and the
monsoon coming soon.
At the same time, it is important to assure a good coordination of
the OSM community from around the world. The statistics below show
great numbers and some challenges with all the new contributors that
participate to the response. Note that these are preliminary
statistics that can be revised later. With less then 3 weeks of
response, we already have edited more the 13 million of objects.
The pbf export file increased from 27 megs april 24 to 84 megs
yesterday. Three times bigger. This is quite awesome. It also shows
how we should adapt to such a rapid growth of the OSM database for
Nepal and maintain quality to adequately respond to the operational
needs of the humanitarian organizations in the field.
Preliminary statistics, Nepal Response Apr-25 – May 15, including
worldwide mechanical edits NB
Contributors *6,456*
Days *11,877*
Changeset Sessions *154,048*
Objects edited (ie. Points, lines, polygons) *13,089,247*
Such a response has brought various discussions on the HOT list on
how to both respond quickly and assure data quality. OSM
crowdsourcing can be compared to an image that we load throug
internet. First, we have a quite inprecise image, coming clearer
gradually. The Mapathons a bit of this role. If unorganized, they
can bring a lot of data quality problems. The worlwide OSM
community can play a strategic role in such a response by
contributing to structure the way the new contributors learn OSM and
edit the map. For the first day of contribution, what is important
is that people better understand what are the various steps and
provide quality data. If we succeed to bring them a second day to
help, this will show quite a significant succcess since the majority
of them contribute only one day for the response.
There will be surely Lessons learned from this Response. For now, I
suggest that people that organize Mapathons communicate with
activation @ hotosm.org <http://hotosm.org> and provide some infos
about the Mapathon
- who Organize this mapathon
- town, country
- Name, email of organizers
- how many experienced osm contributors to support the mapathon
- Nb of people that you plan to receive
- twitter account if you plan to publish updates
- indicate that you give HOT the license to reuse photos that you
publish on Twitter. This can help for outreach and various Blog
updates.
