[Talk-GB] LiDAR in the UK

[SK53]

I think better "Great Britain", don't think NI EA likely to release
anything with a suitable open licence.

WMTS services are quite useful, but it seems one cannot use the underlying
pixel values to derive other data (for instance
<https://gis.stackexchange.com/questions/339074/read-pixel-values-from-wmts-rasterlayer-in-pyqgis>
in QGIS).which is needed for things like building heights. At present I
have to download the rasters & process them: an example of a furniture
factory in Merthyr Tydfil here
<https://wiki.openstreetmap.org/wiki/File:Furntiture_factory_nrw_lidar.png>on
which I'll do a diary entry shortly.

For an idea of what could be possible have a look at the EA's Vegetation
Object Model
<https://environment.data.gov.uk/dataset/ecae3bef-1e1d-4051-887b-9dc613c928ec>
(allegedly Open Data, but Master Map was a significant input, so not sure).

Incidentally, I looked at NRW Lidar in Snowdonia. It mainly covers valleys,
so I don't know how useful it will be for outlying climbing cliffs.
