Several new layers and products released at the portal
18 February 2019
End 2018 - early 2019 several new products and layers were released at the EMODnet Bathymetry portal:
- An inventory and report presenting baseline and coastline data as collected from 21 national authorities. This can be downloaded from the portal as a report together with shapefiles of the baselines and coastlines.
- Best-estimate coastlines were determined from satellite data (typically Sentinel-2 and Landsat-8) and in combination with the Global Tide Surge Model (GTSM) processed into digital coastlines for the European seas at LAT (Lowest Astronomical Tide), MSL (Mean-Sea-Level), and MHW (Mean-High-Water). Coastlines can be viewed as extra layer in the Bathymetry Viewer while documentation can be downloaded.
- Using the GTSM DTM tiles of the 2018 Version can be downloaded both relative to LAT and MSL reference levels as part of the Bathymetry Viewing and Download service.
- A multi-resolution layer has been added consisting of a collection of even higher resolution composite DTMs for selected areas which have been gathered and processed by data providers into High Resolution DTM (HR-DTM) files. The resolution of HR-DTMs varies between 1/32 and 1/512 arc minutes, depending on local data policy of data providers. All HR-DTMs are described with metadata in a special section of the Sextant Catalogue. In total 196 HR-DTM files have been provided can be viewed, interrogated for metadata and downloaded by an extra HR-DTM layer in the Bathymetry viewer.
Further improvement and upgrading of the products and services is underway.
