Mapping Tall Buildings in Dense Urban Areas

These videos are presented to help folks who are doing humanitarian crisis mapping as part of the Humanitarian OpenStreetMap Team, but it is great if anyone else using JOSM finds them of any use. The Humanitarian OpenStreetMap Team always has more requests from humanitarian groups (like MSF, ICRC/RC, WHO, etc) for map data than they have people to help generate the data, please feel free to visit: http://hot.openstreetmap.org/ And see if any of the current activation projects catch your interest!
