		<h1>Getting map and layer data</h1>
		<p>
			This example shows how to retrieve public map data from GIS Cloud.
		</p>

		<p>
            Once loaded, maps are displayed in the list below. You can see their names and ids. <br/>
			Clicking on the <i>Get layers</i> links will retrieve layer data for each map.
		</p>

		<ul id="list"></ul>

		<p>
            The code:
		</p>
		<pre>
function getMapsData() {

    // get public maps
    giscloud.maps.list(function(mapdata) {
        var i, k, map;
