COBS-SWO-Standard Hydrography 2008
Context: This geodatabase is derived from the National Hydrographic Network available from Geobase. The geodatabase includes three data sets of generalized and simplified line work for the Great Lakes, smaller lakes and rivers. It is organized by catchment area but also available as three data sets for the complete study area.
Process: The resulting data sets are a product of a series of line selection and generalization which was completed at the watershed scale (32 watersheds in all) and then aggregated and generalized further for mapping and symbolization at the 1:900,000 scale.
Coverage Area: Southwestern Ontario
