正射遥感影像地图是遥感数字图像经过精纠正（包括投影差改正），并与数字化的简化地形图复合的一种新图．通过在ＧＰＳ，ＧＩＳ数据点控制下遥感图像的精校正，研制出了试验区具有国际分幅规格标准的１∶５万正射遥感影像地图，并直接用于遥感区调试验和成矿预测研究．研究中应用新研制的正射遥感影像（地图）进行地质解译和地质、物探、化探、遥感等多元地学信息综合与复合处理及成矿预测，完成了试验区１∶５万解译地质图、成矿预测图等系列图件，取得了显著效果．
Orthophoto maps are a new type of map of remote sensing digital images that have been fine-corrected (including projection correction) and combined with digitized simplified topographic maps. Through the precision calibration of remote sensing images under the control of GPS and GIS data points, a 1: 50000 orthographic remote sensing image map with international framing specifications in the test area was developed and applied directly to the study of remote sensing adjustment and metallogenic prediction . The application of newly developed ortho-remote sensing images (maps) for geological interpretation and geology, geophysical, geochemical exploration, remote sensing and other multiple geology information synthesis and composite processing and metallogenic prediction, completed the test area 1: 50000 Interpretation of Geology Figure, maps and other mineral prospecting maps, and achieved remarkable results.
