AbstractThe Coastal Information System (CIS) has been developed at the Geological Survey of Canada (Atlantic) (GSC Atlantic) to store data on shore-zone geomorphologic form and material from the Atlantic Provinces of Canada. Data are interpreted from coastal aerial video imagery, stored as lines and points and spatially referenced using the dynamic segmentation feature of the geographic information system (GIS) ArcInfo. An application of dynamic segmentation is explored in the along-shore and across-shore identification of coastal form relationships. Examples of binary and tertiary adjacency relationships are presented from the southeastern coast of Newfoundland, Canada. These data quantify predominant form relationships, and when tabulated independently for specific sections of coast, document similarities and differences in coastal form sequences.
