基于WorldView II图像的钨矿区水体信息提取方法研究——以江西大余县为例
A Water Information Extraction Method Based on WorldView Ⅱ Remote Sensing Image in Tungsten Ore Districts: A Case Study of of Dayu County in Jiangxi Province
摘要
Abstract
Taking the tungsten ore district of Dayu County in Jiangxi Province as an example,the authors analyzed the parameters and relationship between the WorldView Ⅱ bands, selected the best bands for the information extraction of water in the study area, and tested and analyzed a variety of fusion methods to access the suitable fusion method that uses WorldView Ⅱ image to extract the water information in the ore district. The water information in the ore district was extracted by calculating NDWI, analyzing spectral relations between different bands,and making supervised classification. The interpretation accuracies of NDWI, Spectral Relation Act and supervised classification were tested by visual interpretation. The interpretation results were revised to attain the accuracy of 92％ ,and the field verification accuracy can reach 90％ ,which meets the requirements of the work.关键词
