The Shore Unit Classifications Polygons depict the most current areas of Shorezone mapping for the Province of British Columbia. Shorezone is an aerial imaging, habitat classification, and mapping system used to inventory alongshore and across-shore geomorphological and biological attributes of the coast. Habitat attributes are interpreted from oblique aerial imagery acquired during the lowest tides of the year. The mapping project was first developed as an oil spill response tool for British Columbia, and now ShoreZone extends from Oregon to Alaska and has many other uses including ecological studies, marine conservation planning, coastal flooding and vulnerability assessments, and community education.
