<div>In what Kevin Bullock said, is it confirmed that such
satellite images of devastation from Digital Globe released on
newspapers, like by Amnesty (<a moz-do-not-send="true"

target="_blank">https://adam.amnesty.org/asset-bank/action/search?attribute_603=Nigeria+Satellite+Images+January+2015</a>),
are free to use to map on OSM by "manual" comparision?</div>

if you look at the images provided in the link from your mail and
select "View Details" then you can read the agreement that these
images were specifically licensed to amnesty international for their
press release. This means that we cannot use them. <br>

<div>By the way, to represent reality and help the efforts of
identification by people using the map, what about if OSM
renderize buildings tagged "demolished=yes" to represent
better that they actualy are demolished, perhaps with only
outline, or dotted, not shaded? (Anyway, remarking they are
different from standing buldings). </div>

I recall that such tagging schemes were applied for the typhoon
mapping in the Philippines, see e.g. the instructions of <a
href="http://tasks.hotosm.org/project/392">http://tasks.hotosm.org/project/392</a>,
I am not sure if the damage tag has been approved as a general
tagging style though.<br>
