Comparison of coastal marine vegetation mapping methods

This article presents the results of comparisons of DIVA method (French acronym for Vertical Acoustic Detection and Inspection) developed by SEMANTIC TS with optical (towed video systems MOBIDIC and MOOGLI) and acoustic (side scan sonar) methods deployed by IFREMER in three different areas: (i) Les Embiez (Western Toulon), (ii) Saint Raphael (data collected during the INTERREG IIIB / POSIDONIA program, web site) and (iii) Le Bassin d’Arcachon for Zostera meadows cartography. The DIVA method is particularly efficient when it completes the usual methods performed by IFREMER.
