ENVI 软件制作 SPOT5遥感正射影像图方法初探

摘要

This oaoer simoly introduced the SPOT5 satellite and ENIV,analyzed the cause of satellite imagery geometric distortion,discussed the theory and making method of remote sensing hydrological geological mao ortho rectification,and summarized its oroduction technology route, orocess,in order to through the ortho rectification,ensured the orecision of remote sensing image in using orocess.%对SPOT5卫星和ENVI进行了简要介绍，分析了卫星影像产生几何畸变的原因，探讨了遥感水文地质图正射纠正的理论与制作方法，并对其制作的技术路线、工艺流程进行了总结，以期通过正射纠正，保证遥感影像使用过程中的精度。
