Satellite-derived bathymetry (SDB) contributes to a seamless grid
As of September 2024, the Danish Depth Model 2.0 is online. It builds on crowd-sourced data, airborne lidar and satellite-derived bathymetry (SDB by EOMAP). The updated 50-metre model of the Danish Geodata Agency is a leap forward in both data quantity and quality.
The Danish Depth Model (DDM) not only includes vast areas that lacked bathymetric coverage before, but also integrated new data sources. From the beginning of 2024 onwards, EOMAP supported the Danish Hydrographic Office with Satellite-Derived Bathymetry (SDB) for mapping near-coastal shallow water areas. This SDB grid has been integrated with existing and additional data sources, such as airborne lidar and crowd-sourced bathymetry. All datasets have been harmonised, resulting in uniform depth measurements.
The result is a seamless shallow water grid of the Danish coastline and its hundreds of islands. The new DDM addresses
- all stakeholders who value a comprehensive overview of marine areas and depths.
- It is a key tool for accurate storm surge, wave and climate models for maritime planning.
- Moreover, it supports the planning of projects such as wind farms, bridges and tunnels. However, the new 50-metre model is not designed for navigation.
- Last, but not least, these data are embedded into the European Marine Observation and Data Network (EMODnet) Bathymetry.
We congratulate the entire team and say “ Mange tak” for this successful collaboration!
