TrilaWatt: Bathymetry (WMS)

The map service TrilaWatt: Bathymetry (WMS) is intended to provide the annual bathymetrics of the trilateral Wadden Sea for selected years (between 2005 and 2020). The service will be built successively. Definition: “Bathymetry” means the measurement of the topographical shape of the sole of a water body. The term is also often used — analogous to the word “topography” — synonymous with the shape of the water sole. Waters in this context are seas, rivers or closed inland waters. As part of the TrilaWatt project, bathymetric data sets are those representing the elevation distribution in the 12 nautical miles zone, including the estuaries of the Ems, Weser and Elbe estuaries. Through morphological activities of the water soil, such a bathymetric model is only valid for a certain period of time or time. Data generation: The basis for bathymetric products are gridded bathymetric models, which are created using the Functional Ground Model, a data-based hindcast simulation model, via spatial-time interpolation methods from a database of sea and land surveys of various data types. For each year, a gerasterised bathymetric model is created in 10 m resolution for the trilateral Wadden Sea. Product: A 10 m (or 1 m) grid of the trilateral Wadden Sea valid on 01.07. for the above years, wherein the height is deposited at each grid node. The product is provided in GeoTiff format.
