Maps on Taps?

Have just discovered an interesting Government website called Maps on tap which is about errrr.... maps... I think. The blurb says,

Maps on Tap is a DCLG-led initiative undertaken on behalf of UK government with the support of Office for National Statistics, Cabinet Office e-Government Unit and Ordnance Survey. The service is designed to bring together a large amount of location-based information produced by government - to make it easy to access and analyse through a web interface.

If you're wondering how much it cost it was £3.03 million. You'd think they'd pay to hundred or so quid to renew their SSL certificate though.
