The National Scale Frameworks Hydrology data consists of area, linear and point geospatial and attribute data for Canada's hydrology at a national scale. It provides a representation of Canada's surface water features, and data completeness reflects the content of the source, the original Vector Map level 0 (VMAP0) revision 4 hydrographic layers, except where revision editing has been performed. Key value-added characteristics include river flow direction, connectivity and the tagging of geographical name keys to selected rivers, lakes and islands included in the Concise Gazetteer of Canada. The product set for the hydrology theme consists of six groupings: Drainage Network Skeleton, Waterbodies, Islands, Drainage Areas, Supplemental Drainage Features (Hydrometric Gauging Stations and Dams) and Cartographic.

This metadata applies to the Drainage Network Skeleton, Waterbodies, Islands and Cartographic groups of featutes, of the hydrology theme.

Additional Information

Purpose

The Atlas of Canada 1,000,000 National Frameworks Data are a set of integrated base map layers which form the Atlas of Canada National Frameworks Data collection. These data have been compiled at a scale of 1:1 000 000 with the primary goal being to indicate correct relative positioning with other frameworks layers rather than absolute positional accuracy.

Lineage Statement

Originator: Government of Canada, Natural Resources Canada, Canada Centre for Remote Sensing, The Atlas of Canada
