矿产勘查中的遥感技术应用有以下几种技术策略： 根据遥感影像色调、形态异常，直接圈定优先勘查靶区。
1提取含矿地质体的信息及成矿地质信息
通过遥感解译，信息提取，确定矿源层、含矿岩体、含矿脉体、矿化蚀变带等含矿地质体的存在。通过地物波普测试，来寻找含矿地质体存在的波普特征，提取与成矿有关的某些蚀变矿物的波普特征，确定含矿地质体的可能所在。另外，从遥感影像上识别出矿化与矿化体的特殊形态特征，如某些含矿石英脉的浅色纹带。
2.建立遥感找矿模型
矿床模型是对矿床赋存的地质环境、矿床产出的时空规律、矿床特征等矿床本质特征的高度概括，涵盖了矿产形成和保全的全部地质因素，显示现今地质科学对矿床学的研究程度，也显示了将矿床资料理论化的观念认识水平。利用遥感技术在打面积内寻找矿化集中区，将图像上的色、线、环、影纹图像与旷田构造的基本要素（成矿岩体、控矿断裂、围岩蚀变）相结合，提取矿床遥感地质信息，寻找区域找矿标志，并用矿床模式的概念来识别矿床赋存的遥感影特征，建立矿床遥感模型，逐渐成为20世纪90年代以来遥感找矿学的研究热点之一。这也势必能为影像矿床的分析开拓新的思路，把矿床遥感地质研究推进到一个新的层次。
3.多元地学信息综合成矿预测
当前易于寻找的露天矿床及近表矿床越来越少，找矿向隐伏矿及难以识别的矿床转移，找矿难度加大，成矿地质条件及成矿模式十分复杂，单因素的模式难以反映成矿的规律，仅80年代以来，遥感找矿工作者开始以GIS技术为基础，对大量不同来源、不同内容的图像或非图像子量进行综合处理，把原来的地学理论和逻辑思维转换成三维的直观和形象化得、时间和空间模型，把原来的定性概念转化为定量的观念和分析方法，进行多元化地学综合成矿。地物化资料与遥感资料的综合研究提高了地质解译与综合分析的效果与效率，已成为寻找巨型、大型矿床最为有效的找矿方法，也是当前世界找矿趋势。
