@omshinde are there any issue with this being LAS 1.1 not 1.4 specification? I know sometimes the versions force data loss for no longer supported features? Otherwise seems ok, but might be nice to find something a little smaller than 250 MB as the sample.
An example notebook on LiDAR LAS to COPC conversion would be a good example to add. Is it alright if I contribute to this example?
I am planning to use this dataset from NEON for this example - https://data.neonscience.org/data-products/DP1.30003.001
How to access data from NEON is available here: https://github.com/NEONScience/NEON-Data-Skills/blob/main/tutorials/Python/AOP/Lidar/intro-lidar/intro_point_clouds_py/intro_discrete_point_clouds.ipynb
Any thoughts?
