Coastal waters are dynamic and changing environments. Satellite-derived bathymetry (SDB) has been developed to survey water depths and other seabed characteristics by measuring the reflectance of the sea bottom extracted from the upwelling light signal.
Deriving bathymetry from satellite has key benefits being more cost effective, requiring no expensive field surveying, is available for remote and inaccessible areas and quicker to delivery than traditional methods.
ARGANS has developed innovative methodologies for generating IHO-compliant nautical charts derived from satellite multi-spectral images. The main drivers for IHO-compliant SDB are the need to achieve full coverage, a horizontal charting precision compatible with the ship’s own navigational precision, as provided by its current positioning system, and a reliable shallow danger alert.
