Abstract :
This paper analyzes the landscape of Poyang Lake Wetland using RADARSAT-2 polarimetric SAR data acquired on April 7, 2013. H-A-α-Wishart polarimetric SAR data classification method was used to classify the PolSAR data. Then, the landscape was mapped based on the classification result. The landscape was compared to the landscape retrieved from the Landsat ETM+ data acquired on Dec. 26, 1999. To quantify the landscape pattern, the following indices in entire region and different patch type scale were selected to analyze the wetland landscape. The result shows that RADARSAT-2 PolSAR data are suitable for landscape mapping in Poyang Lake Wetland.
