| Abstract: | In this paper,took Yantai as study area,an automatic extraction method of water bodies information is put forward by spectral characteristics and NDVI. This study is based on the comprehensive analysis about diversified water bodies extraction methods. Differentiate water bodies from other features by specialized software and accomplish the automatic extraction of water. At the end of the study,we classified the water bodies by shape index,area and other characteristics,evaluation and precision analysis of results are studied. |
