Montreal Metropolitan Surface Runoff and Basin Mapping from 2024 Lidar

2024 Surface Runoff Modeling - version 2 provides geospatial data identifying topographic depressions and water flow paths in the Montreal metropolitan region. The Montreal Metropolitan Community produced this mapping based on high-precision 2024 metropolitan lidar surveys. The dataset was updated on the platform on April 1, 2026.

Use Cases

• Identify potential flood zones based on mapped topographic depressions.
• Model urban drainage and water flow using the delineated flow paths.
• Plan infrastructure or land use to mitigate water accumulation in identified basins.
• Validate or calibrate hydrological models using high-precision lidar-derived terrain data.

Strengths

• Data is derived from high-precision 2024 metropolitan lidar surveys.
• The dataset is licensed under CC-BY-4.0, allowing for open use and redistribution.
• The platform metadata indicates a recent update on April 1, 2026.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Montreal metropolitan region.
