摘要: AbstractA methodology is developed to extract and process shoreline data, the interface between land water, identified from imagery. Initially, image pixels containing water (water points) pixel locations of land/water (edge are extracted an using either a supervised, threshold approach or newly developed, automated texture-based analysis. Both described demonstrated. Subsequently applied procedure for processing these edge point obtain oriented ordered coordinates. The has several advantages: (1) independent imagery source resolution, that is, specification search directions based on resolution desired unnecessary (2) need additional postprocessing remote-sensed data extracted-edge obviated, not be high quality vectorized. Details entire methodology, including algo...
