Landsat ETM数据在黄土丘陵区对浅层地下水信息的提取

本文利用热红外遥感技术在对影像进行几何校正、数据融合等预处理工作的基础上,进行主成分分析、最优化密度分割等处理,有效提取了研究区的浅层地下水信息,并结合资料分析和野外实地勘查,验证了结果的正确性,同时也为快速、宏观地寻找地下水资源提供了技术和方法参考。

Study of groundwater information extraction from loess hill drought area based on Landsat ETM data

This paper introduced a method to extract the ground water information in loess hill drought area based on landsat ETM thermal infrared data.Based on the pre-processing for the data,such as geometric correction and data fusion,the principal component analysis and best density separation for images were disposed,and the information of groundwater was extracted effectively.With the data analysis and field investigation,the accuracy of the results was validated,which supplies the technique and method for searching the ground water resources fast and efficiently.
