摘要
几何校正是遥感图像处理的一个重要环节,是削弱遥感图像与地面真实形态差异的重要手段。以广东省从化市ETM+遥感数据和GIS数据为例,较深入地分析遥感图像几何校正原理并介绍ER-Mapper7.0遥感软件的几何校正应用,指出提高遥感图像几何校正精度的有效途径和效果分析。
Geometric rectification is an important component in remote sensing image process, and is an essential means to reduce or eliminate differences between remote sensing image and real geographic shape. In this paper it deeply analyzes the geometric rectification theory, taking Guangdong Conghua ETM ＋ remote sensing data and GIS data as an example, introduces the application in geometric rectification of the software ER-Mapper7. 0, and points out the available approach for improving the precision of geometric rectification and the effect analysis.
