Abstract

Integrated coastal zone management (ICZM) and marine spatial planning (MSP) have been proposed for sustainable development of coastal zones. To implement ICZM and MSP, there is a need to establish database and informational networks to collect, share and disseminate information of the present situation of coastal zones. One permanent and concentrated use of coastal zones is hosting aquacultural facilities. This study aimed to develop a method to detect and discriminate aquacultural facilities in Matsushima Bay, Japan, using L-band polarimetric and interferometric airborne synthetic aperture radar (Pi-SAR-L2). Three-component-scattering model and eigenvalue–eigenvector decomposition were applied. The volume-scattering component images of the three-component-scattering model showed raft, longline, and rack aquacultural facilities from the sea surface in good contrast. The double-bounce-scattering component percentage discriminated rack aquacultural facilities from raft and longline aquacultural facilities. The size difference in the raft and longline aquacultural facilities was helpful for discriminating the type.
