LIDAR imagery coming along


Thanks to Andy for drawing attention to this -- it's not a work of art, or an experimental mapping exercise, or even a map of Britain made up of scraps of waste paper stuck onto a board --  but it is in fact the database showing LIDAR coverage of England and Wales.  When this is complete, you will be able to zoom in and pick up incredible details on small segments of the land surface.  I'm not sure what the overall accuracy is, but generally surface altitudes will be accurate to within 25 cms.
