It uses the ArcGIS Server Link for Google Maps at http://google-maps-utility-library-v3.googlecode.com/svn/trunk/arcgislink/docs/examples.html on top of Google Maps and the ABS geospatial web services at http://censusdata.abs.gov.au/arcgis/rest/services
The ABS layers are currently served on their MapServer as a Cached Map Service (I haven't got the Dynamic Map Service working yet on non-cached layers) - so only the core ABS layers are currently working in this demo!
The key lines are these:
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var url = '//censusdata.abs.gov.au/arcgis/rest/services/2011_CED/MapServer'; var agsType = new gmaps.ags.MapType(url, { name: 'ArcGIS', opacity: 0.5 });// map.overlayMapTypes.insertAt(0, agsType);
Enjoy!
