Progress in the Methods for Extracting Aquaculture Areas from Remote Sensing Data

Based on an analysis of remote sensing data sources,the authors classify the methods into five categories,i.e.,visual interpretation,ratio of index analysis,correspondence analysis,spatial structure analysis,and object-oriented information extraction,and summarize their characteristics and application fields.The research direction and development trends are also predicted,which include such application fields as hyper spectral remote sensing data,artificial intelligence,expert systems and non-linear theory.
