摘    要:介绍了利用ERDAS IMAGINE对新疆阿热勒托别地区ETM影像进行几何精校正的方法:先利用ArcGIS对地形图进行坐标配准,然后进行几何粗校正,最后进行几何精校正。通过对校正结果的误差分析并与该地区矢量图比较可知:该方法的校正精度可达到一个像元以内,可以满足工作要求。

关 键 词:ETM影像  坐标配准  几何精校正

Abstract:Remote sensor imagery geometric precision correction is an indispensably technological preparation for imagery processing.In this paper,a method of ETM imagery geometric precision correction for Areletuobie,Xinjiang based on ERDAS IMAGINE is discussed: firstly,have the coordinate of the relief maps matching based on ArcGIS;secondly,do geometric rough correction;finally,do geometric precision correction.Through the error analysis for correction result and compared with the vector data of that area we can draw a conclusion that the correction accuracy of this method was less than one pixel and this method could be used to achieve the demand of work.
Keywords:ETM image  Coordinate match  Geometrical precision correction
