[Talk-GB] LiDAR in the UK

[Tom Crocker]

Thanks both.

UK seems like the flexible option (at least until a referendum), and it's
possible non-central government sources will also be provided. By the way
Jerry, have you come across the Miner2Major veiled landscape project
Jerry?[1] No news on a license or download on the website but I know they
collaborated with NLS.

I guess the valleys are more important for flood modelling. Hopefully the
Welsh uplands will become more populated (by LiDAR!) over the next couple
of years.
