			<content:encoded><![CDATA[<p>For a poster I&#8217;m working on for the <a href="http://http://www.gi4dm-2010.org/haiti.php">Geomatics for Crisis Management</a> conference, I did run some simple stats on the Haiti Planet extracts. After the recent Earthquake, and after the donation of free/libre aerial imagery there has been an increase in user contributions.</p>
<p>These are the total number of users in the Haiti planet extract as of today (the 29th), and dating back to the 14th. For comparison purpose I&#8217;ve added the data for 30th dec 2009. It can clearly be seen that the biggest spike was on 16th, reason being on the 15th the first high quality images were made available for retracing. Then, same thing, same reason, on the 22nd.</p>
<p>first column: date of the extract<br />
second: unique users contributing to the Haiti map<br />
third: Megabytes of the uncompressed extract file (useful for gathering a rough idea of &#8220;detail&#8221;)</p>

			<content:encoded><![CDATA[<p>La mancanza di mappe aggiornate alla reale situazione post-terremoto rischiava di compromettere le attività di salvataggio.</p>
<p>Dopo il terremoto ad Haiti la macchina internazionale degli aiuti si è immediatamente messa in moto, questa volta, una importantissima azione è stata svolta dai volontari <a href="http://osm.org">openstreetmap</a>.</p>
<p>Poche ore dopo sono state rese disponibili foto aeree delle zone colpite, i nostri volontari si sono, indipendentemente, messi all&#8217;opera e hanno iniziato a inserire dati nel nostro database, questo ha portato, nel giro di poche ore, alla generazione di mappe aggiornate dell&#8217;isola, con indicate tutte le strade ancora percorribili, le posizioni dei campi profughi, ponti inagibili, il neo costruito aeroporto.</p>
<p>Le mappe vengono continuamente aggiornate e sono rese immediatamente disponibili per qualsiasi uso, commerciale, o umanitario. Esse sono scaricabili sui navigatori portatili e usate sui cellulari dotati di GPS.</p>
<p>E&#8217; uno straordinario esempio di come un approccio partecipato può funzionare anche in questi drammatici casi.</p>
<p>Un esempio di <a href="http://haiti.openstreetmap.nl/?zoom=14&amp;lat=18.55545&amp;lon=-72.32512&amp;layers=B00FFFFFFFFF">mappa che mostra gli accampamenti spontanei</a>.</p>
<p>Due immagini che mostrano il progresso: la prima è Port au Prince adesso, la seconda, prima del terremoto.</p>
