The EMODnet Bathymetry World Base Layer (EBWB) service is a gridded representation of worldwide bathymetric and topographic coverage adapted for a better representation of seabed morphological features. Based on modern WMTS schema, it allows a fluid and powerful rendering. For the global oceans EBWB1 is composed of the 2018 EMODnet Bathymetric grid around Europe (approx. 100m resolution) and uses the GEBCO 2019 grid (approx. 500m resolution) elsewhere in the marine environment. Land coverage is based on a combination of 30 arc second ASTER GDEM, SRTM3, EU-DEM, and Global 1 second world-wide water body map for the topographic part. This compilation of publicly available data sources have been merged and pre-tiled for rendering, at 10 levels of zoom starting from 1/24th of an arcminute (approx. 75m resolution). The EBWB1 service is available in non-projected system (Lat, Long, WGS84: EPSG:4086), Web Mercator (EPSG:3857), Inspire compliant ETRS-EALA projection (EPSG:3035) and projections adapted to both poles (ESPG 3031 and 3996) Service URL: https://tiles.emodnet-bathymetry.eu/wmts/1.0.0/WMTSCapabilities.xml

DTM data source was created by taking contour lines and spot soundings from Norwegian Electronic Navigational Charts. NOTE: Data east of appr.

This composite Digital Terrain Model (cDTM) is a high resolution bathymetry dataset that covers CASCADES-I, CASCADES-II, COSTEM-1, COSTEM-2, COSTEM-3, COSTEM-4, FORMED-2, FORMED-4 and FORMED-6 cruises. Multibeam data acquired in 2008, 2009, 2010, 2011, 2013, 2014 and 2015 on board the R/V Sarmiento de Gamboa and the R/V García del Cid with an Atlas Hydrosweep DS-3 and an Elac Seabeam 1050D echo-sounder.

Bathymetric data resulting from hydrographic surveys for cartographic purposes and/or port management. Surveys carried out in accordance with the IHO S-44 standard.
