Canadian Hydrographic Obstacles Point Data From CanVec

CanVec, a digital cartographic product from Natural Resources Canada, provides a dataset of hydrographic obstacles like falls and rapids across Canadian territory. The data originates from multiple authoritative sources including the National Topographic Data Base and satellite imagery, complying with international geomatics standards. It is distributed by the Government of Yukon.

Use Cases

• Map hydro obstacle density (e.g., falls, rapids) across Canadian watercourses for hazard assessment.
• Integrate Water Obstacle Point features with other CanVec hydrographic layers like Waterbody and Water Linear Flow for comprehensive watershed modeling.
• Analyze the spatial distribution of Permanent Snow and Ice features in relation to hydro obstacles for climate impact studies.
• Use Water Well and Spring point data alongside obstacle locations for groundwater and surface water interaction analysis.

Strengths

• Data originates from Natural Resources Canada's CanVec product, a multi-source compilation from authoritative databases like the NTDB.
• Complies with international geomatics standards, ensuring interoperability and quality topographical information.
• Incorporates updates from satellite imagery coverage including Landsat 7, Spot, and Radarsat.

Limitations

• Specific sample size, row count, and column definitions for the 'Water Obstacles Point' subset are not provided in the input.
• The description covers the broader 'Hydro Features' theme; granular details on obstacle types and attributes within this specific point layer are unknown.
