Of all the methods for geometricrectificationof remote sensing imagery, the Collinearity Equation Modelis usually considered to have the best accuracy.
在遥感影像几何校正方法中，通常认为精度最高的是共线方程模型。

When the precise geometricrectificationof TM imagery was made with the ground control points selected from topographic map in scale of 1:100000, the accuracy of half a pixel is high.
