Discussion <strong>and</strong> conclusions<br />
The Haiti earthquake clearly demonstrated that<br />
optical remote sensing is a valuable post-earthquake<br />
damage assessment tool <strong>and</strong> that satellite/aerial<br />
data providers have the capabilities to timely trigger<br />
image acquisition <strong>and</strong> to make available the data to<br />
the humanitarian community. But it also<br />
demonstrated that above all the establishment of<br />
good coordination bodies equipped with proper<br />
supporting tools is crucial.<br />
But if unhappily, persistent clouds had covered the<br />
affected areas on the days after the event, all the<br />
optical data would have been useless. The role of<br />
radar remote sensing (not only aimed at identifying<br />
the main faults by measuring ground displacements)<br />
in the post-earthquake damage assessment should<br />
certainly be a research priority in the radar<br />
community. As an operational alternative, the<br />
capabilities of new low cost devices aimed at<br />
per<strong>for</strong>ming ground surveys should be further<br />
exploited. Figure 11 shows the user interface <strong>and</strong><br />
some sample pictures of a LCMMS (Low Cost Mobile<br />
Mapping System) equipped with 4 webcams <strong>and</strong> a<br />
GPS (Figure 10) aimed at acquiring georeferenced<br />
frames. The system, developed by ITHACA <strong>and</strong><br />
Politecnico di Torino, allows acquisition of about half<br />
million frames <strong>and</strong> 60 thous<strong>and</strong> GPS points during a<br />
5 days ground survey in Port-au-Prince.<br />
