摘要
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.
An orthophotomap is a new type of map that is accurately corrected for geometry, and is composed with a simplified topographic map. In the study, an orthophotomap of Landsat TM453 image is made, scaled 1∶50000, up to an international standard of topographic map. The orthophotomap has been used in the regional geological survey and minerogenetic prediction in the studied region. The interpreted geological map, linear and circular structural map and minerogenetic prediction map in the studied region have been made based on the geological interpretation and multisource information processing of geological, geochemical, geophysical and remote sensing data with the orthophotomap.
