    • Abstract
  • As an important part of a tidal flat,tidal channels are critical to the understanding of topographic features of a tidal flat and its evolution.In this paper,the panchromatic band remote sensing data received by SPOT5 on May 7,2005 were used.The tidal channels information was extracted with the region growing method by selecting appropriate seed points and gray level threshold.Then the grid method was used to calculate fractal dimensions from the extracted tidal channel information.The results have provided a reference for the rational development and utilization of resources in Jiuduansha tidal flat.
