Regarding the identification of inhabited areas, do you know about
the “Global Urban Footprint” dataset? See for example:<br clear="none">

<div>Hi all,</div>
<div><br clear="none">
</div>
<div>Many thanks to the 293 OSM contributors and to the amazing
validators who have already participated to the mapping in the
Equateur province, since May 8th.</div>
<div><br clear="none">
</div>
<div>The 17th task was published this morning to respond to the
needs expressed by Doctors without Borders and the Congolese
Ministry of Health.</div>
<div>Yesterday afternoon, while visiting the emergency operation
center team at the Ministry, it was said that the
identification of inhabited areas in OSM (mapped as
residential landuse) is particularly helpful to them at the
moment, as well as the detailed mapping of the urban areas, to
better follow the people that have recently been in contact
with confirmed cases. </div>
<div><br clear="none">
</div>
<div>While there's been at least one new case detected each day
in the area since the outbreak declaration, they also wished
additional areas to be mapped as well.</div>
<div>Some tasks are already ready to be added but in order to
keep up with the quality of the data produced (i.e. keeping
the rythm with the validation), <b>we need more validators</b>.</div>
<div><br clear="none">
</div>
<div>If you are already participating to this validation, thank
you so much! If you are not yet but have already significantly
contributed to OSM, maybe it's time to give it a try...</div>
<div><br clear="none">
</div>
<div>If you want an overview of the area covered by these
mapping tasks so far, you'll find one here:</div>
