Evaluation of alternative bathymetry data sources for MAREANO: A comparison of Olex bathymetry and multibeam data for substrate and biotope mapping
Elvenes, Sigrid; Dolan, Margaret F.J.; Buhl-Mortensen, Pål (NGU-Rapport (2012.030), Report, 2012)The MAREANO (Marine AREA database for NOrwegian waters) seabed mapping programme generates a wide range of products, including sediment and benthic biotope maps. Production of these maps relies heavily on full-coverage ...
