This line layer from the ShoreZone Inventory divides the shoreline in 8 shoreline types based on substrate type. This classification is a simplification of the BC Shoreline Classification.The ShoreZone Inventory characterizes several physical parameters within shoreline segments. The majority of the shoreline is described by line data. Polygon features exist in some areas with extensive shallows. The ShoreZone Inventory includes all saltwater shorelines statewide. It was completed between 1994 and 2000 using aerial videography collected at low tide.
