Abstract

With the rapid development of science and technology, it has become an inevitable trend to use remote sensing technology to monitor, investigate and analyze urban waters. The rapid and accurate extraction of water bodies from remote sensing images has become an important water extraction method. Based on SPOT4 images, this paper applied Ostu Threshold method and Maximum Likelihood Classification method to conduct experiments on water body extraction and compared the advantages and disadvantages of supervised classification and unsupervised classification in urban waters area extraction. Experimental results show that the Maximum Likelihood Classification method has the highest accuracy, and the Threshold Method has the fastest efficiency, but small rivers cannot be distinguished.
