I've been experimenting with MapServer with the help of LP Archaeology to see if it's a viable option to load layers onto a Google Maps interface. Here's the first result: http://www.online-archaeology.co.uk/GoogleMap/pages/wms_test.htm Click on 'Military Roads' and that fires off a request to a Web Mapping Service hosted by LP Archaeology. We're now testing Web Feature Service so we can load layers of clickable objects.

After a few tests with WFS and parsing the GML it looked like it put too much load on the client, so we tried a different approach. We loaded the WMS as normal and then captured the point where a user clicks and sent this point and other paramters back to MapServer as a GetFeatureInfo request. This returns HTML back to the map which I then load into the InfoWindow. Here's the outcome of the GetFeatureInfo test: http://www.online-archaeology.co.uk/GoogleMap/pages/wms_test_feature.htm Click on 'Military Roads', wait for the layer to load, then click on any polyline.

This example is now offline, but we're working on some stuff that really shows the potential of this technology. I'm waiting for a licence to use some data - if I'm granted a licence I'll post the demo URL.
