| 摘 要： | 在分析ＳＰＯＴ预处理级图像（ＩＡ、ＩＢ、ＩＡＰ）特点的基础上，提出了在一定精度范围内，将ＩＢ级图像像坐标变换为ＩＡ级或ＩＡＰ级图像像坐标的两种变换方案。试验结果表明，两种变换方案皆具有较高的变换精度，但方案２的精度优于方案１的精度，且已用于生产作业。

| Abstract: | Basing on analysing the characteristics of SPOT preprocessing level images (1A. 1B, 1AP), two methods which transform level 1B image coordinate into corresponding level 1A or 1AP image coordinate within certain precision range is proposed. The experiment result demonstrates that these two transformation methods all have high transformation precision. But the precision of the second method is better than that of the first. These transformation methods have been applied to operation of practice. |
