遥感Landsat TM数据在水文地质测绘中的应用

摘要

在西北陇县-淳化岩溶区找水项目中，地质水文地质测绘采用遥感技术。通过应用Landsat TM数据影像资料，充分发挥遥感的优势，提高了工作效率，创造了良好的经济效益。%Landsat TM Data and Images is used in searching underground water in karst zone in Long Xian-Chun Hua area in Northwest China. This has not only made the best use of remote sensing technology, improved work efficiency , but also cut costs and made great economic benefits .
