Winnipeg Water Infrastructure LiDAR Point Cloud Index

An index of LiDAR files for the City of Winnipeg, created by the Water and Waste department. Each file contains a point cloud detailing location, elevation, and surface type, with data organized by year and file type. The index includes links to individual 1km x 1km tiles and full annual collections.

Use Cases

• Model terrain elevation and surface types for flood risk assessment using the Elevation and Surface Type data from point clouds.
• Analyze spatial distribution of water infrastructure assets by joining point cloud data with the Boundary and Year columns.
• Compare seasonal changes in ground surface or infrastructure by filtering point clouds based on the Season column.
• Assess data density and coverage for specific city areas using the Minimum Density and File Type columns to select appropriate tiles.

Strengths

• Data is organized by specific 1km x 1km tiles for granular spatial analysis.
• Includes metadata such as Horizontal Datum, Vertical Datum, and LAS Version for geospatial accuracy.

Limitations

• The total number of LiDAR point cloud files and their cumulative size is unknown.
• Sample data is unavailable, preventing immediate assessment of point density or attribute completeness.
