| Abstract: | Coastal zone is one of the most human activities affected and developed areas.It is of great importance to monitor the dynamic change of coastline rapidly and accurately for the application and management of sea area.Satellite remote sensing has such prominent advantages as macroscopic,full-time,fast,high-frequency and low cost.The progress of research in coastline auto-extraction was summarized based on remote sensing and GIS.Threshold segmentation,edge detection,mathematical morphology,neural network classification,wavelet transform,fractal dimensions were emphasized.Their advantages and disadvantages were analyzed.The future research considerations were suggested based on the present insufficiency and the application of coastline extraction in coastal aquaculture was discussed. |
