Lidar for free!

As of the beginning of this month all of the Environment Agency Lidar data for England has been released as open data. It can be accessed through a new portal. Some have complained of problems, and it can be rather slow loading the background mapping, but I've been able to get my hands on lots of interesting stuff already.

The data is released under Open Government licence which allows commercial use, so it's all there to play with as you see fit. Sadly, in the process we have lost Wales which devolves elsewhere (though through some odd [and yet to be repeated] glitch I managed to download a chunk of the Lleyn peninsula just the other day, so the data seems to be there - hopefully someone will sign it off for release before too long).
