lazrs
orlaszip
backend. - LAS/LAZ streamed/chunked reading/writting.
- COPC support over files.
- COPC support over https with
requests

Examples
Directly read and write las
import laspy
las = laspy.read('filename.las')
las.points = las.points[las.classification == 2]
las.write('ground.laz')
Open data to inspect header (opening only reads the header and vlrs)
import laspy
with laspy.open('filename.las') as f:
print(f"Point format: {f.header.point_format}")
print(f"Number of points: {f.header.point_count}")
print(f"Number of vlrs: {len(f.header.vlrs)}")
Use the 'chunked' reading & writing features
import laspy
with laspy.open('big.laz') as input_las:
with laspy.open('ground.laz', mode="w", header=input_las.header) as ground_las:
for points in input_las.chunk_iterator(2_000_000):
ground_las.write_points(points[points.classification == 2])
Appending points to existing file
import laspy
with laspy.open('big.laz') as input_las:
with laspy.open('ground.laz', mode="a") as ground_las:
for points in input_las.chunk_iterator(2_000_000):
ground_las.append_points(points[points.classification == 2])
API Documentation and tutorials are available at ReadTheDocs.

:
