Description

Hydrographic lines, points, and polygons are the natural and constructed features which occur on waterbodies and/or watercourses and may pose hazards or impediments to water flow and/or navigation.

Shorelines are the derived line between water and land. This class is derived from waterbody and used for cartographic purposes and web mapping services.

Water bodies are polygon features (natural and constructed) that describe various realizations of surface water at a medium scale of 1:10K in Southern Ontario, 1:20K in Northern Ontario and 1:50K in the Far North.

Watercourse are line features (natural and manmade) that describe various types of flowing water at a medium scale of 1:10K in Southern Ontario, 1:20K in Northern Ontario and 1:50K in the Far North. (Replaced Water Virtual Flow dataset.)
