EasyGSH-DB: Bathymetry in 2012

Definition: "Bathymetry" means the measurement of the topographical shape of the sole of a body of water. The term is also often used interchangeably with the word ‘topography’ for the shape of the sole of the water. Waters in this context are seas, rivers or closed inland waters. As part of the EasyGSH project, bathymetric data sets are those that represent the height distribution in the German Bight including the estuary areas of the Ems, Weser and Elbe estuaries. Due to morphological activities of the body of water, such a bathymetric model is only valid for a certain period or time. Data generation: The basis for bathymetric products are rasterized bathymetric models, which are created using the Functional Soil Model, a data-based hindcast simulation model, using spatial-temporal interpolation methods from a database of sea and land surveys of various data types. For each year from 1996 to 2016 inclusive, a gridded bathymetric model is created in 10 m resolution for the German Bight and additionally in 250 m resolution for the Exclusive Economic Zone for the year 1996. Product: Each 10 m grid of the German Bight is valid from 01.07. for the years 1996 to 2016, where the height is stored at each grid node. 250 m Exclusive Economic Zone grid (1996). The product is provided in GeoTiff and Shapefile format. Quotation for this dataset (Data DOI): Sievers, J., Rubel, M., Milbradt, P. (2020): EasyGSH-DB: Subject area - Bathymetry.
