Inventory and monitoring of coastal aquaculture and fisheries structures provide important baseline data for decision-making in planning and development, including regulatory laws, environmental protection and revenue collection. Mapping these structures can be performed with good accuracy and at regular intervals by satellite remote sensing, which allows observation of vast areas, often of difficult accessibility, at a fraction of cost of traditional surveys. This study is based on interpretation of satellite imaging radar data and a detailed image analysis procedure id described. The report aims at the necessary technology transfer for and operational use of the approach indicated in other similar environments.
