<h1>Fire engine callouts</h1>
<p>The fire brigade in the <a href="http://www.brandweer.nl/amsterdam-amstelland/">Amsterdam-Amstelland</a> area responded to over <strong>62,415</strong> incidents between January 2006 and September 2010. The <a href="http://www.hackdeoverheid.nl/wp-content/uploads/2011/03/BrwAAincidenten_reshaped.zip">data set</a> was first released for the <a href="http://www.appsforamsterdam.nl/">Apps for Amsterdam</a> 2011 contest.</p>
<p>The <a href="http://www.imergis.nl/shp/2012-Veiligheidsregios-watergrenzen-Shp.zip">boundaries</a> of the Joint Emergency Services Districts (<span lang="nl">veiligheidsregio's</span>) have been obtained from <a href="http://www.imergis.nl/">Imergis</a>.</p>
<p>This visualisation was created by <a href="http://www.twitter.com/emacgillavry">Edward Mac Gillavry</a> from <a href="http://www.webmapper.net/">Webmapper</a> using <a href="http://www.cartodb.com/">CartoDB</a> and <a href="https://github.com/CartoDB/torque">Torque</a>.</p>
<p>Learn more about how we converted the data <a href="http://webmapper.net/lab/fire-engine-callouts-part-1-from-csv-to-geojson/">from <abbr title="Comma Separated Value">CSV</abbr> to GeoJSON</a> and <a href="http://webmapper.net/lab/fire-engine-callouts-part-2-animated-map-with-torque/">created the animated map</a>.</p>
