The data is based on the EUSeaMap 2021 data, downloaded from EMODnet Seabed Habitats thematic portal (https://emodnet.ec.europa.eu/en/euseamap-2021-emodnet-broad-scale-seabed-habitat-map-europe). The dataset includes an ecosystem component raster layer for all 18 habitat types listed under MSFD BHT in the original EUSeaMap dataset, excluding the habitat “NA” where the classification was not applicable. The habitats are formed by combining the biological zone (infralittoral/circalittoral / Offshore circalittoral) and substrate information (coarse, mixed, mud, sand, mud or sand, rock and biogenic reef), forming altogether 18 layers. Original vector data was transformed to 1x1km grid rasters, one data set for each BHT.

regards interoperability of spatial data sets and services 2010-12-08 Data source: EUSeaMap 2021 Data processing: Original vector-based data on habitats (MSFD BHT) was first transformed 100x100m raster. The final value for the 1x1km grid was assigned to the habitat that had the biggest area within each grid cell. As contrary to HOLAS2, no aggregation to the habitats was made and the division of deep and shallow circalittoral habitats was kept. Thus the number of habitats used in HOLAS3 increased to 18. Data quality: Broad habitat types describe the habitat distribution on a regional/large scale. They do not describe local scale variation in habitat distribution. Scale in the original data varies from 1:1 500 to 1:1 000 000. All data is coming from one source, but given the uncertainties in the original data and data gaps in the southern Baltic Sea, the overall confidence can be considered to be moderate. A separate confidence map of the original data, compiled by the EMODnet Seabed Habitats project, can be downloaded from the EMODnet Seabed Habitats thematic portal (https://emodnet.ec.europa.eu/en/euseamap-2021-emodnet-broad-scale-seabed-habitat-map-europe) and viewed in the EUSeaMap 2021 technical report (https://archimer.ifremer.fr/doc/00723/83528/88577.pdf).
