Seabed Habitat (EUNIS) - FR5300017 Abers - Cote des legendes (Compilation of maps) - FR004012

Mapping of the Natura 2000 site FR5300017 Abers - Cote des legendes was jointly performed in the framework of three different actions: (i) the Natura 2000 convention for Brittany, and (iii) CARTHAM Project. It is based on the interpretation of various types of data from a number of surveys carried out between 2005-2012 both in the intertidal and subtidal zones. Additionally the seabed « Carte G » from the French hydrographic survey (SHOM) was used in the interpretation process. In the tidal zone the identification was made by interpreting coastal ortho-photographs from BD Ortho (2005 et 2009) and digitising them on scale 1 : 2000ème with further qualification of the polygons based on ground truth data. A confidence score in the [0-100] scale has been assigned to each polygon (SUM_CONF field) The compilation comprises the following various data sources. Lamarche S., Bajjouk T., 2013.
