Treatment of topographic and bathymetric data acquired at the Truc-Vert Beach during the ECORS Field Experiment

Abstract : The aim of this paper is to present the topographic and bathymetric surveys acquired during the international ECORS mission (March-April 2008) at Truc Vert Beach, SW of France. Topographic surveys have been done with an accuracy of about 2.5cm in the horizontal directions and 3cm for the elevation. Using both a GPS kinematics (by foot or implemented on a quad) and a theodolite, an area extending from the dune to the nearshore region was covered. In this paper, we present the methods developed in order to merge the different dataset. The acquisition and treatment of this large dataset was made possible thanks to the coordination of a large work force available on the field comprising numerous international institutions. From this work, together with the lower sample rate topographic data gathered over the last 10 years, Truc Vert Beach is the most documented beach of the French Coast.
