Examples

Filtering

This example shows how you can extract points from a file and write them into a new one. We use the classification field to filter points, but this can work with the other fields.

import pylas

las = pylas.read('pylastests/simple.las')

new_file = pylas.create(point_format=las.header.point_format_id, file_version=las.header.version)
new_file.points = las.points[las.classification == 1]

new_file.write('extracted_points.las')

Creating from scratch

This example shows how you can create a new LAS file from scratch.

import pylas
import numpy as np

las = pylas.create()

array = np.linspace(0.0, 15.0, 10000)
las.x = array
las.y = array
las.z = array

las.write('diagonal.las')

Using chunked reading & writing

This example shows how to use the 'chunked' reading and writing feature to split potentially large LAS/LAZ file into multiple smaller file.
