It is easy to operate, strong practicability, rapid speed and high geometric precision to geometrically correct by using ERDAS IMAGINE software. Geometric correction provides technological preparation for TM imagery further processing. The precision degrees of geometric correction for remote sensing imagery influence to extract accurately the remote sensing information. By using ERDAS IMAGINE8. 6 software, a simple analysis is made on the geometric precise calihration for TM imagery in Fuzhou area of Jiangxi. The principle of geometric precise calihration is expounded by describing the cause of geometric distortion of remote sensing images, moreover, a simple and practical scheme of precise calibration and its arithmetic are given. Theoretically, this calihration methoxl has an error less than one pixel, which can meet the routine emending accuracy required.
