Many remote sensing applications are devoted to the coastal and ocean sector. Representative case studies are presented in the special issue Advances in Remote Sensing of Coastal and Ocean. remote sensing techniques represent a powerful tool for landslide investigation:applications are traditionally sea surface temperature, marine habitat into three main classes, although this subdivision has some limitations and borders are sometimes fuzzy in coastal and ocean. Remote sensing combined with geographic information systems. can be used as a technology tool to obtain information about the object quickly and accurately, including objects in coastal and ocean areas. Remote sensing data essentially can be used as an alternative technology in obtaining information at a cheaper cost when compared with the conventional way.
