Canadian Elevation Points And Contour Features

250,000 elevation features include Contour and Elevation Point entities from Natural Resources Canada's CanVec product. This digital cartographic reference originates from the best available data sources covering Canadian territory, offering quality topographical vector data compliant with international geomatics standards. It is a multi-source product from the National Topographic Data Base, Mapping the North process, Atlas of Canada, GeoBase, and satellite imagery updates.

Use Cases

• Analyze elevation point density and distribution to model terrain characteristics across Canadian territory.
• Extract contour line features for hydrological modeling and watershed delineation studies.
• Integrate elevation point and contour data with other geospatial layers for land-use planning and infrastructure development.

Strengths

• Contains 250,000 distinct elevation features, providing substantial coverage.
• Originates from authoritative sources including Natural Resources Canada's National Topographic Data Base.
• Complies with international geomatics standards, ensuring interoperability.

Limitations

• Specific row counts for individual feature types (Contour vs. Elevation Point) are not detailed, limiting granular analysis.
• The ESRI REST and HTML file formats may require specialized GIS software for full utilization.
• Update frequency and temporal coverage of the underlying source data are not explicitly stated.
