Object-Oriented Method of Water Extraction Based on ETM + Images
摘要
Abstract
This paper used an object-oriented approach to extract water body from the ETM + imagery. Firstly,it got the image object through the image segmentation and explored the optimal segmentation scale for water extraction;then,it used ENVI FX tools to create rule sets and extract wa-ter body. Comparing with the traditional maximum likelihood classification method,the object-oriented method of water extraction performed signifi-cantly better in the overall accuracy,kappa coefficient,producer accuracy and user accuracy. Therefore,the object-oriented method has obvious advantages and good prospects.关键词
