Canadian Hydrographic Obstacles From CanVec Topographic Data

Water Obstacles Poly - 50k - Canvec contains hydrographic obstacle features like falls and rapids across Canadian territory. The dataset originates from Natural Resources Canada's multi-source CanVec product, which complies with international geomatics standards. It is distributed by the Government of Yukon via the GeoYukon platform.

Use Cases

• Map and analyze the distribution of hydro obstacles like falls and rapids across Canadian water networks.
• Integrate hydro obstacle features with other CanVec layers such as Watercourse or Waterbody for comprehensive hydrological modeling.
• Use the polygonal data to assess terrain difficulty or navigation hazards in specific geographic regions.

Strengths

• Data originates from Natural Resources Canada's authoritative CanVec cartographic reference product.
• Compiles information from multiple sources including the National Topographic Data Base and satellite imagery like Landsat 7.
• Complies with international geomatics standards for quality and interoperability.

Limitations

• Specific row count, column schema, and sample data are unavailable for assessing dataset scale and structure.
• The 'yk-oglyk' license may have specific use restrictions that require review before application.
