[Talk-GB] LiDAR in the UK

[SK53]

Yes agree with this, just document status of NI stuff even if we can't use
it.

I wasn't aware of that project, or even Strawberry Hill Heath, but have
tended to avoid the general area as it is favoured for illegal off-road
activities

which are pretty incompatible with the sort of survey work I do on
biological sites. I know more about Rainworth Heath on the other side of
the wood, as it used to be grazed by NWT's flying flock. Clipstone itself
has the remnants of a hunting lodge belonging to King John so not
surprising there are medieval aspects. The big local lidar project is
the Nottingham
Cave Survey <https://geoserver.nottinghamcity.gov.uk/caves/>

The original EA data was also predominantly valleys, but they realised that
the extra expense of complete coverage was relatively small compared with
overall utility. Therefore post-2017 they aimed for complete coverage. I'm
less familiar with what the objectives & timeframes are for either SEPA or
NRW ongoing lidar coverage..
