Canadian Surface Water Network Hydrographic Features

250,000 hydrographic features represent Canada's surface water network, including watercourses, waterbodies, and obstacles. The dataset is compiled by Natural Resources Canada from multiple authoritative sources like the NTDB and satellite imagery, ensuring quality topographical vector data compliant with international standards.

Use Cases

• Map watercourse density and connectivity across Canadian territory using the vector network data.
• Analyze the distribution of hydro obstacles like falls and rapids relative to waterbody features.
• Integrate water linear flow and permanent snow and ice features for hydrological modeling.
• Use the multi-source data from NTDB and Landsat 7 for validating or updating regional water feature maps.

Strengths

• Contains 250,000 distinct hydrographic features for comprehensive national coverage.
• Compiled from multiple authoritative sources including the National Topographic Data Base (NTDB) and satellite imagery (e.g., Landsat 7, Spot).
• Provides vector format data compliant with international geomatics standards.

Limitations

• Specific column names and data schema are not provided, complicating initial analysis.
• Sample data is unavailable, preventing preview of attribute structure and values.
• The dataset size and row count beyond the feature total are unknown.
