Laspy

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

Laspy is compatible with Python 3.8+.

Features

LAS support.
LAZ support via lazrs or laszip backend.
LAS/LAZ streamed/chunked reading/writting.
COPC support over files.
COPC support over https with requests package.
CRS support via pyproj package.

Examples

Directly read and write las ```Python 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)

```Python import laspy

with laspy.open('filename.las') as f: print(f"Point format: {f.header.pointformat}") print(f"Number of points: {f.header.pointcount}") print(f"Number of vlrs: {len(f.header.vlrs)}") ``` Use the 'chunked' reading & writing features

```Python import laspy

with laspy.open('big.laz') as inputlas: with laspy.open('ground.laz', mode="w", header=inputlas.header) as groundlas: for points in inputlas.chunkiterator(2000000): groundlas.write_points(points[points.classification == 2])

```

Appending points to existing file

```Python import laspy

with laspy.open('big.laz') as inputlas: with laspy.open('ground.laz', mode="a") as groundlas: for points in inputlas.chunkiterator(2000000): groundlas.appendpoints(points[points.classification == 2]) ```

API Documentation and tutorials are available at ReadTheDocs.

Installation

Laspy can be installed either with pip:

``` pip install laspy # without LAZ support

Or

pip install laspy[laszip] # with LAZ support via LASzip

Or

pip install laspy[lazrs] # with LAZ support via lazrs ```
