Time-sequence aerial photos often constitute the only source of data to determine past shoreline changes. This report presents a method for obtaining shoreline change data from base maps constructed from time-sequence sets of aerial photos, with the image of the aerial photos superimposed at the constant scale of each base map. Shoreline position and other features of interest, such as vegetation line location and orientation of breaking wave crests near the coast, etc., are then traced on each base map. A comparison of each base map from the different sets of aerial photos will provide shoreline change data through time. Author
