RVCA Watercourses

Abstract
|
RVCA Watercourses represent the Rivers, Streams, Creeks, Drains etc within the RVCA, as a centerline feature class. They have been delineated using the MNRF LIO watercourse standard and using the existing LIO Watercourse layer as a base. This dataset is used extensively for Subwatershed & Catchment Reporting, as well as Regulations. Rivers large enough to meet the waterbody standard are also captured as polygons (See RVCA Waterbodies).
The data capture approach is partially based on MNRF's "Large Scale Data Capture Specification for Hydrographic Features" technical documentation. The main hydrographic classes are “watercourse” and “waterbody”. Water features that meet minimum width requirements (>30m wide continuous) are captured as waterbodies (polygons); otherwise they are captured as watercourses (line). In addition, most waterbodies have one or more watercourse (“virtual flow”) features within them, to provide continuity to the flow network.
Please see the 'RVCA Waterbodies' dataset for the associated polygon hydrographic features.

Methodology

The data capture approach is partially based on MNRF's "Large Scale Data Capture Specification for Hydrographic
Features" technical documentation. The main hydrographic classes are “watercourse” and “waterbody”. Water
features that meet minimum width requirements (>30m wide continuous) are captured as waterbodies (polygons);
otherwise they are captured as watercourses (line). In addition, most waterbodies have one or more watercourse
(“virtual flow”) features within them, to provide continuity to the flow network.
