Canadian Hydrographic Features From CanVec Topographic Data

Hydro Features provides a vector network of Canadian surface waters, including watercourses, waterbodies, and permanent snow and ice. The dataset originates from Natural Resources Canada's multi-source CanVec product, compiled from the National Topographic Data Base, satellite imagery, and other authoritative sources.

Use Cases

• Map waterbody and watercourse distributions for hydrological modeling across Canadian territory.
• Analyze hydro obstacle features like falls and rapids for river navigation or hazard assessment.
• Integrate permanent snow and ice vector data with satellite imagery for climate change studies.

Strengths

• Sourced from Natural Resources Canada's authoritative CanVec cartographic reference product.
• Compiled from multiple data sources including the National Topographic Data Base and Landsat 7, Spot, and Radarsat satellite imagery.
• Complies with international geomatics standards for vector topographical information.

Limitations

• Specific row count, column details, and sample data are unavailable, limiting preliminary assessment.
• Data freshness is uncertain beyond the metadata update date; the underlying source compilation date is not specified.
