摘要

An important user of hydrographic sur-veys done by Hydrographic Offices traditionally has been nautical cartography. Hydrographic surveys are required for chart production. But the tasks of the Federal Maritime and Hydrographic Agency (BSH) are not limited to navigation. Their scope is wide and continues to expand (e.g. CZM, coastal protection, coastal engineering). More and more different demands are being made by the users. This leads to hydrographic surveys for multiple uses. How to fulfil the needs of different users with just one survey campaign is shown by an example. In 2001, the 'Jadebusen' had to be surveyed for BSH purposes as well as for special coastal engineering projects. This meant high and quite different demands on accuracy, vertical reference and processing. Multi-beam, single-beam and laserscan data had to be combined. This paper describes the planning, execution and processing of the surveys with a focus on height correction with PDGPS (precise differential GPS using carrier phase corrections) and on the combination of seaborne and airborne data. Problems and solutions are being discussed.
