They could be both. When I asked the question a few months ago
concerning similar structures elsewhere in Africa I was told that
it can take a while for something to be built & finished, but
it can also be a case of something has become disused & the
roof removed. In either case, it would be a relatively quick job
for someone to clean it up and add a roof.<br>
<br>
Something to consider - since the satellite imagery was taken the
structure could have changed - now be complete & with
residents. In some areas corrugated iron is available & a roof
could be added in a few hours. <br>
<br>
The other option is something like a pig sty - a small building
with a roof for the animal to shelter in with a compound or
compounds attached to it - pigs, goats, etc..<br>
<br>
I can't see for sure what that particular image is showing -
probably the animal compound but it could just as easily be the
residence in decay or slow construction.<br>
<br>
The outlines we are tracing today could be unchanged on the map
for many months / years. I try to make sure they will appear in
the data in one format or another because at least someone using
just the map data can look at it and say "There's some kind of
building there" & perhaps another say "That's John's farm,
it's gone now but the road still goes through there" - you need
the local knowledge that we just can't possess.<br>
<br>
Acceptable options to me all involve the structure being traced
and appear in <a href="https://wiki.openstreetmap.org/wiki/Key:building" target="_blank">https://wiki.openstreetmap.org/wiki/Key:building</a> .
Whatever it is, it's construction includes barrier=wall which is
also a valid option. I have no wish to offend someone who is
probably a better mapper than me, so I try not to alter tags if
they appear in the wiki, but I will probably do so if they don't
render in Mapnik or Humanitarian style renderings.<br>
<br>
If it was me doing the tracing I would keep it simple;<br>
barrier=wall<br>
or<br>
building=yes<br>
<br>
Hope this helps<br>
<br>

[22:45] <supersonic3974> Hey, quick question. What are
these things that look like buildings under construction? They
seem to be everywhere. Here's an example:
<a href="http://imgur.com/ccS03xv" target="_blank">http://imgur.com/ccS03xv</a>
<br>
<br>
I have that same question coincidentally enough.
<br>
<br>
They look like buildings with no roof.
<br>
<br>
Are they buildings under construction or structures that lost
their roof?
<br>
<br>
My guess is we wouldn't outline them since they probably are not
inhabited, but I don't know for sure.
<br>
<br>
I'll make sure he gets an answer if someone replies here.
<br>
<br>
Cheers,
<br>
