INTERPRETATION OF SHORELINE POSITION FROM AERIAL PHOTOGRAPHS

Abstract

A review of some of the potential sources of error associated with the use of aerial photographs to map shoreline change is presented. The influence of both tides and waves in the estimation of the position of the wet sand line on the subaerial beach is included. The use of the relatively new digital photogrammetry as applied to shoreline mapping is discussed and suggested as having the potential for being a superior method for this application.
