<p>Hey Davey,</p>
<p>thanks for response and it's great to see that you find the paper
interesting. I really like your idea of having a another blog post
explaining the "behind the scenes" part of writing the paper. I
think that this would also be a great opportunity to reply to some
of the other feedback that I've received. I apologize in advance,
that I might need a bit more time to actually write that piece.
But feel free to remind me, when you don't see something in the
next 2-3 weeks. ;)</p>
<p>One quick reply on the "metadata". Actually my personal opinion
is that ideally the Tasking Manager (and any other tool that we
use) should collect as few metadata as possible. Especially in the
world of open source and open data I think it is really important
, that our community can be free from tracking any personal
information. So that's why I actually do not have a wish list for
this.</p>
<p>The questions you raise are definitely important and such an
analysis would be very interesting for the humanitarian mapping
community in general. However, again my personal feeling is that
we need to find more indirect ways to differentiate between OSM
contributions by "locals" and "non-locals". A student that works
in our group has put together a blog post, where he was trying to
address the "localness" of OSM data:
<a class="moz-txt-link-freetext" href="http://k1z.blog.uni-heidelberg.de/2020/11/23/exploring-localness-of-osm-data-an-analysis-using-the-oshdb-and-ohsome-api/">http://k1z.blog.uni-heidelberg.de/2020/11/23/exploring-localness-of-osm-data-an-analysis-using-the-oshdb-and-ohsome-api/</a>
Maybe this can provide some further ideas on how to do this.</p>
<p>Have a nice week,</p>
<p>Benni</p>
<p>PS: @Nicolas thanks for sharing the mail also on the

<div>Wow!!! 😍 Super impressive in-depth research you got there!
To go from crunching raw OSM history files to extracting
meaningful information from regression models to an actionable
agenda for improving future humanitarian OSM initiatives, is
no small feat and the analysis pipeline you've put forward is
a huge step towards understanding the status quo and improving
our work as a community. Bravo! 👏👏</div>
<div><br>
</div>
<div>I wonder, is there any "wishlist" metadata the HOT tasking
manager could collect on its users that would allow for more
interesting angles on the analysis? Cataloguing which regions
users consider themselves as a "local" comes to mind, as then
we could understand how many map features are added by remote
users vs locals</div>
<div><br>
</div>
<div>Looking forward to checking out the source code when it's
published! Especially that you went into detail to analyze the
type of edits made in each changeset is really impressive. I
for one would love to read a nice explanatory blog post about
pulling off such a herculean feat of data extraction (I'm
curious especially how many hours/days/computing power/€€ the
analysis took)<br>

<p>Dear Humanitarian OSM Community,</p>
<p>today I wanted to share with you some very recent
research findings that we've just published in the
journal "Scientific Reports". The title of the article
is "The evolution of humanitarian mapping within the
OpenStreetMap Community" and I can ensure you that we
tried really hard to provide a comprehensive and
detailed picture on what many of us in this community
have been working on for the past decade.</p>
<p>This analysis encompasses all humanitarian mapping
projects organized through the <a
href="https://tasks.hotosm.org/" rel="nofollow
noreferrer" target="_blank" moz-do-not-send="true">HOT
Tasking Manager</a> since 2012 (start of the
available data), enabling us — for the first time — to
cast a longitudinal perspective on the intersecting
effects of mapping efforts, socio-economic, and
demographic characteristics.</p>
<p>I also wrote a blog post which can give a quick
summary of the main findings here:<br>

<p>I hope that our research can be of interest and
relevance not only for academics, but for a broader
and much more diverse group as the humanitarian OSM
community is one and I'm curious to hear about your
thoughts and ideas about it. So feel free to get in
contact with me in case that there is something not
clear or if you would just like to discuss your
thoughts and ideas. <img alt="(smile)"

<p><span style="color:rgb(0,0,0)">Please note that our
insights about humanitarian mapping in OSM only
provide an incomplete picture which lacks an
on-the-ground perspective and neglects other remote
mapping tools, since we considered only the mapping
that was organized through the HOT Tasking Manager.
For instance, humanitarian mapping that has been
organized by local residents on the ground is not
considered here. This limitation is accompanied by
the fact that our analysis only focused on two types
of mapped objects </span><span
style="color:rgb(0,0,0)">(buildings, highways). As
you know mapping in OSM comes with a much greater
variety of </span><span style="color:rgb(0,0,0)">potential
map objects (e.g. health facilities, schools, water
points), which can add particular value in
comparison to other geographic data sets. We are
aware of the fact that our definition of
humanitarian mapping is therefore oversimplified and
the results must be taken with a grain of salt. In
many regions of the world there is no clear
distinctive line between humanitarian and
non-humanitarian mapping activities as the
humanitarian and non-humanitarian OSM communities
are not disjoint.</span></p>
<p>For the ones of you that I do not know in person,
here a short background on myself and why we did this
research:<br>
I'm currently doing a PhD at Heidelberg University and
are based at the Heidelberg Institute for
Geoinformation Technology. I got interested in
humanitarian mapping in OSM in 2013 when I attended a
seminar by João Porto de Albuquerque (who is one of
the co-authors of the paper) and the mapping in
response to Typhoon Haiyan happened. Since then I've
looked into various aspects of mapping in OSM and
supported the Missing Maps project with developing
MapSwipe, and general OSM analyses and stats. It was
really great to see many of you in person at the HOT
Summit and State of the Map in Heidelberg in 2019.
This research mainly evolved out of these many
discussions back then and many small analyses that
I've conducted in the following and the again
following discussions I had around these with João,
Jennings, Sven and Alex. Some parts of it are also
visualized on a website, which you can check here: <a
