就目前所发表的大多数文献来看,有关利用遥感技术进行矿产勘查的尝试主要依赖两个方面;或者是直接检测所感兴趣的光谱信息;或者是卫星影象线性体与矿体之间的相关关系。第一种研究方法在绝大多数难以进入的地区未能取得明显的成功。这是由于目前卫星传感器的光谱和空间分辨率较低,只具备探测大规模铁帽的能力,而难以可靠地分辨那些特征较细微的岩石蚀变或圈定小规模岩石露头,后者在大多数区域都是最普通的目标。
For the most part of the literature published so far, attempts to exploit remote sensing technology for mineral exploration rely mainly on two aspects: direct detection of the spectral information of interest; or correlation between satellite imagery and ore bodies relationship. The first method of research failed to achieve significant success in the vast majority of hard-to-reach areas. This is due to the low spectral and spatial resolution of current satellite sensors and their ability to detect large-scale iron caps, and the difficulty of reliably resolving those subtle rock alterations or delineation of small-scale rock outcrops, The area is the most common goal.
