Feb 18, 2022 · Laspy Laspy is a python library for reading, modifying and creating LAS LiDAR files. Laspy is compatible with Python 3.6+. 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)

This example shows how you can extract points from a file and write them into a new one. ... import laspy las = laspy.read('tests/data/simple.las') new_file ...

def write (self, pt): '''Writes the point to the file if it is append or write mode.

Writing To be able to write a las file you will need a LasData . You obtain this type of object by using one of the function described in the section above use its method LasData.write () to write to a file or a stream. import laspy las = laspy.read("some_file.laz") las.points[las.classification == 2] las.write("ground.laz") Chunked Writing

I wanna save some files in .las format and I've found this code : import laspy import numpy as np hdr = laspy.header.

To open a file in write mode, you must provide a laspy.header.Header instance which will be immediately written to the file. If you provide a header instance in read mode, the values of that header will be used in place of those in the actual file. If a file is open for write, it cannot be opened for read and vice versa.
