Advance of Remote Sensing Application to Tidal Flat Resource Monitoring in Coastal Zone

Chen Yong(Shanghai Institute of Geological Survey,Shanghai 200072,China)  
Along with the increasing development of urbanization,tidal flat is now serving as the most important resources of land reserves for coastal cities.As a sensitive belt of sea and land interaction,silt tidal flat is characterized as muddy surfaces,densely covered and frequently varied tidal creeks.Therefore,the traditional field observation has been restricted by the difficulty of access,however,the development of remote sensing techniques make it possible for the coastal investigator to monitor the dynamic changes of coastal zone at low cost and in an efficient way.This paper reviewed the current state of the use of remote sensing in estuaries and coastal tidal flat.Recent advances of four main application aspects including shoreline extraction,retrieval and analysis of elevation at mudflat,bathymetry and surface suspended sediment concentration retrieval are introduced.To date,the most common remote sensed techniques used in coastal zone can be classified into four categories:photogrammetry,satellite optical remote sensing,SAR as well as Lidar.Through systematical analyzing the mechanism,technical characteristics and advantages and shortages of the four categories techniques,the author finds that despite these considerable advances have been made,lack of suitable remote sensing data and not-perfect data processing methods are the remaining challenges to impede the improvement of survey accuracy in coastal zone.In order to improve this situation,it is to suggest that future studies should focus on the study of combination of different remote sensed information,hyperspectral data mining and data processing methods on SAR and Lidar data.
