Coastal benthic habitat map of Natura 2000 site "Côte de Trestelà Paimpol", estuaires du Trieux et du Jaudy et archipel de Bréhat

This map covers both the intertidal zone and subtidal zones of the study sites. It is made from high resolution remote sensing data - both acoustic and optical - from various surveys carried out over the period 2008 to 2013 of various types: (i) multibeam echosounder (MBES), side scan sonar (SSS), RoxAnn acoustic ground discrimination system (AGDS), (ii) ortho-photography (the "Ortholittorale survey" from 2000), (iii) topographic and bathymetric lidar . It was complemented by (i) underwater video,(ii) sediment and biological grab samples, (iii) ground truth data from surveys in the tidal and infralittoral zone using GPS, annotations and photography. The habitat classification was a synthesis of the main habitat classifications, namely: Generic habitats from the Habitat Directive (EUR 27), Elementary habitats from the French Cahiers d'habitats, The Rebent classification and EUNIS level 4 as much as possible. Map scale is in the range of 1:20000, with local improvements to 1:10000.
