| 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:

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:

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. |
