Visualizing LiDAR Data with Leafmap¶

This notebook demonstrates how to visualize LiDAR data using leafmap.

Installation¶

Uncomment and run the following cell to install the required Python packages.

In [ ]:

# %pip install "leafmap[lidar]" open3d

# %pip install "leafmap[lidar]" open3d

Import libraries¶

In [ ]:

import leafmap

import leafmap

Download data¶

Download a sample LiDAR dataset from Google Drive. The zip file is 52.1 MB and the uncompressed LAS file is 109 MB.

In [ ]:

url = "https://open.gishub.org/data/lidar/madison.zip"
filename = "madison.las"

url = "https://open.gishub.org/data/lidar/madison.zip" filename = "madison.las"

In [ ]:

leafmap.download_file(url, "madison.zip", unzip=True)

leafmap.download_file(url, "madison.zip", unzip=True)

Metadata¶

Read the LiDAR data

In [ ]:

las = leafmap.read_lidar(filename)

las = leafmap.read_lidar(filename)

The LAS header.

In [ ]:

las.header

las.header

The number of points.

In [ ]:

las.header.point_count

las.header.point_count

The list of features.

In [ ]:

list(las.point_format.dimension_names)

list(las.point_format.dimension_names)

In [ ]:

leafmap.view_lidar(filename, backend="ipygany", background="white")

leafmap.view_lidar(filename, backend="ipygany", background="white")

Panel¶

Visualize LiDAR data using the panel backend.

In [ ]:

leafmap.view_lidar(filename, cmap="terrain", backend="panel", background="white")

leafmap.view_lidar(filename, cmap="terrain", backend="panel", background="white")

Open3D¶

Visualize LiDAR data using the open3d backend.

In [ ]:

leafmap.view_lidar(filename, backend="open3d")

leafmap.view_lidar(filename, backend="open3d")
