title: Good examples of MapServer / OpenLayers
body: <p>I want to convince some clients to use MapServer and OpenLayers. Please can anyone suggest <strong>attractive websites</strong> to show off the possiblities!  </p>
  
  <p>The clients will be impressed by:</p>
  
  <ul>
  <li>A <strong><a href="http://blog.spatialkey.com/2010/02/comparing-thematic-maps-with-density-heatmaps/" rel="noreferrer">density map</a></strong> (otherwise known as a heat map, colour-shaded grid coverage, contour plot...). </li>
  <li>The ability for the user to download the underlying data for the density map, restricted to the area being viewed, in some format such as netCDF. </li>
  <li>Standard OpenLayers stuff. Zooming, panning, scale bar, overview map... </li>
  <li>Different base layers. Could be WMS, Google, Bing... </li>
  <li>Searching for a placename, map is panned to display the place. </li>
  <li>Exposing the heatmap data for other people to use in mashups as <a href="http://mapserver.org/ogc/wms_server.html#wms-server" rel="noreferrer">WMS</a> or <a href="http://mapserver.org/ogc/wcs_server.html" rel="noreferrer">WCS</a></li>
  </ul>
  
  <p><a href="http://mapserver.org/" rel="noreferrer">MapServer.org</a> is back up but demo.mapserver.org seems to be down right now :( But from memory their examples didn't have the "wow" factor. The <a href="http://dev.openlayers.org/examples/" rel="noreferrer">OpenLayers examples</a> demonstrate only one or two features per example - I want something to wow the clients by showing <strong>all</strong> the capabilities in one example. </p>
  
  <p>PS If you have good examples that use some other open source tools, post them by all means. But just JavaScript please: customer says no rich client.</p>
  
  <p><strong>EDIT</strong> Come on StackOverflow, someone must have an example that uses a density map?? I'm even offering a bounty now...</p>
