Potential Water Flow Beds from Quebec LiDAR Survey

Quebec's provincial LiDAR acquisition project produced vector layers mapping potential water flow beds based on topography. The data is distributed by water drainage unit (UDH) in Geodatabase or GeoPackage format and is used to support forest operations. It is a preliminary product from the Ministry of Natural Resources and Forests and the Ministry of the Environment.

Use Cases

• Analyze the geographical position of potential flow beds to model watershed topography.
• Classify watercourse nature (permanent or intermittent) for hydrological studies.
• Support forest operation planning by mapping preliminary water flow paths within UDH divisions.
• Integrate potential flow bed layers with other hydrographic data for comparative analysis.

Strengths

• Data derived from provincial-scale LiDAR sensor acquisition project.
• Distributed by water drainage unit (UDH), respecting natural watershed boundaries.
• Available in multiple GIS formats including Geodatabase and GeoPackage.

Limitations

• Preliminary vector layers that do not replace reference hydrographic data.
• Does not account for surface deposit nature or underground pipes.
• Specific spatial and temporal coverage details are not provided.
