Blake,
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
When I trace something like this, I use the key-value landuse=construction. I
also am in the habit of annotating traced objects with imagery date on the
object, which is more useful for something like this than, for instance, doing
so for travelways. --Courtland

For these I use building=constructuion. I think landuse=construction is
for larger areas like a construction site where a large building or parking
lot or something is being built. Adding the date is not a bad idea but
probably not essential; doesn't hurt to add it though.

On Sat,
I am not sure that this construction tag helps us about the status of these
houses. The imagery can be a few years old. Also from my experience in Haiti,
people build rapidly the first floor and then start to mount walls for the
second floor. But this can stay unchanged for years.
UAV Imagery
I have been putting these buildings in as building=construction but they
can also be simply building=no_roof or barrier=wall to indicate that there
is a structure there to help the people on the ground identify where they
are and indicate that there is something there.
It is not possible for
I agree with the idea of organizing some tagging conventions is
important so our W. Africa mapping is consistent. And that conventions
will vary by region.
There really are not that many tags we use for 80-90% of what we map so
we should be able to get them pretty consistent.
I also agree

Hi, Blake,
I thought some of them were walled areas around buildings (common in
urban areas). At any rate I did not trace them as buildings. However, it
would be a good idea to have some examples in the wiki.
Yes, they are hard to tease out,
My personal practice is to tag all such buildings as
abandoned:building=yes. My reasoning is that uncovered walls will soon
deteriorate, so the odds that this is a building under construction are low.

We used to tag them like that however our thinking has evolved. I have seen at
least one that is uncovered in old bing imagery but had a roof in newer
imagery. Also Pierre has mentioned that in Haiti and elsewhere he has seen such
buildings under construction for long periods of time. They may
Building=no_roof is certainly descriptive, with building=construction as
my second choice. Preference?

Tom, it's mostly building=yes if you don't know what kind of building it is.
For the roof, we can maybe extend

I really don't know, no roof is more descriptive but is not in the db. There is
a roof=no tag that could be added as a second one but I think that implies
something more permanent. I guess I would lean toward building=construction but
I am not leaning very strongly.

Hi,
New user supersonic3974 asked this question in irc last night but didn't
get a reply:
[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: http://imgur.com/ccS03xv
I have that
Well, the documentation says that we have landuse=construction [1] and
there's also an abandoned key [2]; however, I don't know what to do if one
isn't sure if it's still under construction or already abandoned. I, for
myself, didn't draw an outline for these buildings for the same reason as
