Airborne geophysical methods have a great potential in delineating subsurface information down to some hundred metres depth. This information is essential for planning purposes for manifold geoscientific, economic or environmental questions, like, e.g., utilization and protection of freshwater resources, land utilization or industrial planning. These data integrated into a three-dimensional geographic information system provide a powerful tool for spatial planning. Beside the geological or geophysical basic information also changes of surface and subsurface data in time and space may be documented by repeated surveys. In this contribution, typical applications of helicopter-borne electromagnetics in Germany are shown. The surveys were conducted by BGR using a six-frequency RESOLVE system. Emphasis is placed on the mapping of coastal aquifers, what comprises the mapping of freshwater-saltwater interfaces, the outline of saltwater intrusions and submarine freshwater occurrences, and the mapping of clay distributions.
