Laspy

Laspy is a python library for reading, modifying and creating LAS LiDAR files.

|Build Status|

Introduction

Laspy is a pythonic library for reading, modifying and writing LAS files. Support for LAZ is limited to reading LAS version 1.0-1.3 files. Laspy is compatible with Python 2.6+ and 3.5+.

Laspy includes a set of command line tools which can be used to do basic file operations like format translation and validation as well as comparing LAS files.

Example

A simple example to show the basics of Laspy. Here we create an output file that only consists of terrain points from the input file:

from laspy.file import File
import numpy as np

inFile = File('/path/to/file.las', mode='r')

I = inFile.Classification == 2

outFile = File('/path/to/output.las', mode='w', header=inFile.header)
outFile.points = inFile.points[I]
outFile.close()

API Documentation and tutorials are available at PythonHosted.

Installation

Laspy can be installed either with pip:

pip install laspy

or by running the setup script included in the source distribution:

python setup.py build --user
python setup.py install --user

Laspy is only dependent on numpy and should therefore work on Linux, OS X and Windows as long as a working installation of numpy is available.
