SMMS: Bathymetry (WMS)

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 SMMS project, bathymetric data sets are those representing the height distribution in the German Bay, including the estuaries of Ems, Weser and Elbe. 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 the years 1960-2020, a gerasterised bathymetric model in 10 m resolution will be provided for the German Bay. Product: A 10 m grid of the German Bay valid on 01.07. for the year, wherein the height is deposited at each grid node. The product is provided in GeoTiff format together with source maps (before and after, shapefiles). The bathymetries are related to the EasyGSH-DB project, but cover a longer period of time. Service: The service visualises selected years from the SMMS research period.
