Shore-zone classification data for the Canadian Beaufort Sea coast form part of a GIS database, the Coastal Information System (CIS), developed and maintained by the Geological Survey of Canada (GSC-Atlantic), Natural Resources Canada, at the Bedford Institute of Oceanography in Dartmouth, NS. Coastal attributes in the CIS have been interpreted and mapped from low-level, oblique, aerial photography and video imagery with accompanying audio commentary. The CIS is hierarchical in that coastal forms are classified based on four increasingly detailed levels of description. The coastal data consist of line segments with attributes describing the physical form and material at scales ranging from 1:10 000 to 1:250 000. In the CIS, the coast is divided into three shore-parallel zones (backshore, foreshore, nearshore). Each zone is segmented separately based on homogeneous physical characteristics. A glossary has been developed to control the language used to describe each zone. The use of objective physical criteria for coastal classification enhances the utility of the CIS for a wide variety of applications.
