The MIT Lincoln Lab ALIRT system has been collecting 3D imagery of Haiti for the last 15 days or so, and will continue for at least another 7-10 days.  It’s an airborne mapping system that measures the 3D position of surfaces and geolocates them accurately.  Much of our data is being made publically available.  (see, for example, https://jtf-haiti-alirt-lidar.box.net/shared/8kxylga1ig and http://www.opentopography.org/index.php/blog/detail/a_quick_look_at_nga_... ).
