[pdal] What attributes would you add to your pointcloud

[Sion Williams]

One of the uk devolved ones 😉 .Going to blow peoples minds when they see
the full Entwine dataset. Processing everything easily on a single i7
laptop with 64gb of ram...did not think it would be possible in Opensource.
When the dust settles probably 4months time would love to do a show and
tell document...and can be less cryptic on the country.

Howard I learnt a lot from your youtube video with "ESIP CCC:cloud
optimised point cloud with Howard Butler" ...i reccomend people check it
out...esp for the links of viewer.copc.io & validate.copc.io

Cheers
Sion
