Sažetak
Satellite Derived Bathymetry (SDB) uses satellite or other remote multispectral imagery for depth determination. Recent advances in satellite technology (spectral, radiometric, temporal and spatial resolution improved) have increased the potential of this method as a source of hydrographic data. This method became widely used in the last few years. SDB is a survey method founded on analytical modelling of light penetration through the water column in visible and infrared bands. SDB become the most important low cost source of hydrographic data. In this article SDB method was applied by using Landsat 8 satellite images to get bathymetric data in the area of Kaštela Bay in the Middle Adriatic. The procedures and algorithms of SDB processing, as well as reconnaissance tool, were described. The “preliminary” bathymetric map of the Kaštela bay, obtained by the SDB method for the only one satellite scene, was compared with Electronic nautical chart 47 of that area with satisfying result. Finally, improvement of the presented SDB methodology was proposed.
