This paper analyzes the geometric characters and imaging theory of SPOT satellites and discusses the geometric correction of SPOT5 simages based on collinearity equations with ground control points.

• 摘要根据SPOT卫星的成像原理和特点，讨论了对SPOT5卫星影像按共线方程法进行有控制点的几何纠正的方法，经对关中、陕北和陕南三种地形的影像纠正结果进行对比检验，证明了该方法精度达到了较高水平。
