Abstract
    In June 2005, Fugro Pelagos, Fugro Geoid and Actimar SAS conducted an extremely challenging Airborne Hydrographic LIDAR survey of the Gulf of Morbihan for the Service Hydrographique et Océanographique de la Marine (SHOM) of France. The objective of the project was to validate LIDAR technology for hydrography and charting purposes and assess performances in detecting submerged objects. The Gulf of Morbihan in Brittany was chosen by SHOM as the location for this technology evaluation, due to the diverse and complex conditions that characterize the coastal zone in this area. This paper will focus on the operational challenges that needed to be considered when planning and executing this survey. It will also demonstrate how LIDAR was used successfully in this very complex environment, when the risks were well understood and properly managed.
