High Resolution Bathymetry of Littoral Zones Based on Very High-Resolution Worldview-2 Images

Abstract

Very high-resolution remote sensing imagery of coastal areas provides valuable information, where the highest biodiversity of the planet accumulates. With the great improvements in spatial resolution obtained in recent years for the satellite WorldView-2 (WV2), we have available very high-resolution images with a sub-metric panchromatic band and multispectral bands below two meters resolution. Its eight multispectral bands allow obtaining a greater spectral information of the complex coastal environments, allowing more complex algorithms for coastal monitoring. These new features allow the detection of the coastal seabed with sufficient resolution for bathymetric and benthic studies. This research, in the frame of the ARTeMISat-2 project, has developed algorithms based on Radiative Transfer Modeling of the seawater (RTM) to obtain highresolution bathymetries using WorldView-2 images.
