Seabed habitat map (EUNIS classification system) performed by Andromede Oceanologie within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence fran├ºaise pour la biodiversit├®, AFB). Digital data sources : Sonar (2012, 2010, 2007), bathymetric datas (2007-2010), orthophotos (2009), historical data (2007), GPS (04/2012, 06/2010). Ground truth data sources (2010-2012) : Diving, direct human observations, sea-viewer. Map confidence rated by Ifremer : 78% (Areas with doubtful outlines and/or classification are mentioned in the "VAL_COMM" field).
