On devasted areas (by wars or natural catasptrophes): Hi Jeremy, Pierre, Blake and mappers around, I've been mapping around since Baga massacre have been reported, images on OSM look very good enough in many areas of Northern Nigeria and Cameroun to trace buildings or, at least, road network, alternatively using both sources of images from Bing and Mapbox on iD (sure, better if can get more hi-res images for the hole area). Makes one glad to read people looking for helping to improve mapping in such regions. Thinking in devasted areas tagging, wouldn't it fit to map the real situation if in demolished buildings it were just added a tag like "demolished=yes"? It's not hard to find those devasted areas and buildings by comparing the images in OSM with recent publicly released satellite images. Guess it would be a great help for humanitarian efforts related to destruction and population displaced (I think also on tasks of Gaza, tsunamis, earthquakes and similars situations). In what Kevin Bullock said, is it confirmed that such satellite images of devastation from Digital Globe released on newspapers, like by Amnesty (https://adam.amnesty.org/asset-bank/action/search?attribute_603=Nigeria+Satellite+Images+January+2015), are free to use to map on OSM by "manual" comparision? 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). Sorry if bad english. What do you think? Cheers, Sérgio
