Coastline Remote Sensing Prediction Based on Tide Zoning Correction
In this paper,a coastline prediction scheme for the muddy coast region is put forward and realized based on multi-site tide level interpolation and Remote Sensing techniques.Firstly,artificial coast and instantaneous waterline are extracted from multiple remote sensing images.And then,tidal harmonic analysis together with the linear interpolation and zoning correction method are applied for actual tidal level obtainment at the discrete points along the waterline during the imaging time.The average slope of the bank and the average high tide point position are calculated under the trigonometric function similar principle.The discrete points are then connected to form the natural shoreline.The remotely sensed coastline is then combined and formed by the natural shoreline and the artificial shoreline.The practical application proves that the scheme of coastline is in coincidence with the in situ surveyed mean high water mark points.So this scheme can be used for fast determination of the muddy coastline.It can also provide the monitoring method and data support for the spatial variation of beach resources.
