说明：  对于高分辨率遥感卫星数据而言，目前几乎都提供了有理函数模型（RFM）来进行图像校正（SPOT系列提供了有理函数模型之外还提供了严格轨道模型）。对遥感影像进行校正目前最常用的就是使用有理函数模型来进行校正。
(For high-resolution remote sensing satellite data, almost all rational function models (RFMs) are currently available for image correction (the SPOT series provides a rational orbit model in addition to the rational function model). Correcting Remote Sensing Images Currently, the most common use is to use rational function models for correction.)
