2015 Aerial LiDAR Point Cloud of Québec Territory

A 3D topographic point cloud representation of territory captured via aerial LiDAR in 2015. The technology recorded up to 400,000 3D points per second, providing detailed ground and surface elevation data. It was sourced from XEOS Imaging Inc. for the Government and Municipalities of Québec.

Use Cases

• Create a digital terrain model (MNT) from the 3D point cloud data for hydrological analysis.
• Calculate tree heights and vegetation volumes by analyzing point cloud elevation details above ground.
• Generate level curves and building roof maps for urban planning and 3D city modeling.
• Perform volume calculations for terrain or infrastructure projects using the dense 3D point data.

Strengths

• High-density data collection capable of recording up to 400,000 3D points per second.
• Provides accurate altitude measurements for ground details and elements, even under dense vegetation.
• Data is provided in multiple formats including LAS (standard for LiDAR), SHP, and CSV.

Limitations

• Specific spatial extent, point count, and resolution details for the Québec territory are unknown.
• Data is from a single year (2015), which may not reflect current terrain conditions.
