Andy Waddington, vice president of bathymetric services at Hexagon, is a hydrographer and an experienced mariner with a long career in surveying at sea. He started his career in hydrography in the Royal Navy, UK, where he was originally trained in singlebeam echosounders, electronic positioning and horizontal sextant angling in the days before GNSS. During his 25 years in the Royal Navy he was active in the transition to multibeam echosounders, the universal adoption of GNSS as the primary positioning system and the introduction of ROVs as a major survey tool. Over the past ten years he has turned his attention towards other emerging survey techniques and has been involved in the development and operation of bathymetric Lidar, satellite-derived bathymetry and unmanned surface vessels. Andy Waddington has a BSc in Systems and Management and an MSc in GIS, and is a Chartered Marine Scientist, a Fellow of the IMarEst, a Member of the Chartered Institute of Civil Engineering Surveyors and an Associate Fellow of the Marine Institute.
