Thanks for the plug Tim :-)
The slippy map with relief tiles made from the data and optionally
contours also made from the data is here: http://relief.raggedred.net.
This covers a mostly very flat area, yet significant details are
visible. It does show a number of places where ditches and other small
water courses might be missing from OSM and therefore places to survey.
The contours are minutely detailed using the 50cm data. If I was
creating contours that are more generally useful I'd try the 2m data I
think.

Ahh correction, there *is* data at 25cm and 50cm in some areas (where
flooding is a threat) but it looks as if the 1m and 2m covers the
country.
Chris has written a post here also:
http://chris-osm.blogspot.co.uk/2015/09/more-lidar-goodness.html so
we're already playing with it.

Hello,
back in June we had a thread announcing that this LIDAR data was due
to be released. Well some of it has.

http://environment.data.gov.uk/ds/survey#/
I think it's just for England, and appears to be 1m and 2m composite
DTM and 1m and 2m DSM They do intend to release a Tiled version next,
and I think 50cm and 25cm are coming also
What can we do with it?
Cheers,
Tim
