用遥感技术来研究地下水,实质上是在各类遥感图象上寻找各种间接标志,以解译控制水文地质规律的众多因素,进而分析水文地质条件。遥感图象的种类很多,目前常用于水文地质研究的主要有航空象片、卫星图象和热红外扫描图象。
Using remote sensing technology to study groundwater is essentially looking for various indirect signs on various remote sensing images in order to interpret the many factors controlling the hydrogeology and then analyze the hydrogeological conditions. There are many types of remote sensing images. Currently, there are many aerial images, satellite images and thermal infrared images commonly used in hydrogeological research.
