Abstract
With remote sensing resolution data from Landsat-8, GF-1 and Sentinel-1 as the data sources, we used the object-oriented multi-resolution segmentation method to extract the area of Po Lake in Anhui. First, the multi-resolution segmentation method is used to segment the object, and then rule sets are established to extract areas of water bodies on three maps to calculate the area of lake water. The research result shows that the object-oriented multi-resolution segmentation method can realize efficient extraction of open water areas and facilitate disaster monitoring and emergency response.
