Synergy of Gps, Photogrammetry and Insar for Coastal Zone Monitoring

This paper reports on research that aims to develop a technique for rapidly monitoring coastal erosion over wide areas, by deriving synergy from three integrated measurement technologies. These technologies are the global positioning system (GPS), automated digital photogrammetry using imagery acquired with a small format digital camera, and synthetic aperture radar interferometry (InSAR). The technology for all three of these techniques has been available for the last few years but only recently has it become potentially accessible for multiple use by coastal managers. Through integration, it is anticipated that the optimum monitoring solution in terms of spatio-temporal coverage, precision, accuracy, time and expense will be achieved.
