EMODnet Bathymetry New Release
A new version of the EMODnet Digital Bathymetry (DTM) has recently been published which now covers all of Europe's seas. The resolution of the EMODnet DTM has been increased from 1/4 x 1/4 arc minutes to a grid with 1/8 x 1/8 arc minutes (circa 230 metres). The new DTM is based upon approx. 6,000 gathered survey datasets and composite DTMs as provided by 29 data providers from 16 countries.
The new release contains 1.092.115.678 data points (28.799 rows x 37.922 columns) which are divided over 16 tiles which can be downloaded freely in various formats. In addition, several upgrades have been applied to the Bathymetry Viewing and Download service for viewing and browsing the new EMODNet DTM.
The EMODnet-Bathymetry portal is being developed in the framework of the European Marine Observation and Data Network (EMODnet) as initiated by the European Commission. It provides services for discovery and requesting access to bathymetric data (survey datasets and composite DTMs) as managed by an increasing number of data providers. The portal also provides a service for viewing and downloading a harmonised Digital Terrain Model (DTM) for the European sea regions that is generated by the EMODnet Bathymetry partnership on the basis of the gathered data sources.
The next release of the EMODnet DTM is planned for summer 2015 by incorporating even more surveys, including coastal, and further improvement of the digital bathymetry. So far all surveys and composite DTMs are originating from Hydrographic Offices, Research Institutes and Government Departments and provide an overall coverage of approx. 50-60 % of European waters. For the next DTM release also industry are encouraged to come forward with survey data contributions.
