Abstract
This report summarises the investigation of two sets of Radarsat imagery for the purpose of automated coastline extraction. Studies in the Bay of Fundy, Nova Scotia area highlighted potential problems in identification of shoreline in a region with large tides, steep topography, and large expanses of inter-tidal flats. Studies on the Canadian Beaufort Sea coast highlighted problems associated with storm surges. Many of the problems noted here are not exclusively associated with radar imagery. Any satellite imagery will have similar problems. The conclusion is that, in extreme regions such as the two examined here, automated shoreline extraction to the accuracy required for a 1:50,000 map may not be currently possible.
