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 />
