| 摘 要： | 通过实证研究的方法对高分辨率ALOS卫星数据进行质量分析，结合ALOS数据特点，提出了ALOS原始影像数据的预处理方法和处理流程。研究结果表明： ALOS数据预处理工作量较大，且预处理方法要求较为严格，因此，在开展大规模、大范围、大区域、大精度、短周期的图件更新、动态监测等应用时，应考虑将ALOS卫星图像与其它卫星图像结合使用。

| Abstract: | This paper has analyzed the quality of high resolution ALOS satellite images by an empirical analysis method.Based on characteristics of ALOS images,the authors present methods and the flow of ALOS raw images preprocessing.The result shows that the images of ALOS should be used in combination with the images of other satellites when we conduct large-scale,large-area,high-precision and short-cycle land use map updating and dynamic monitoring.This is because the images of ALOS have such shortages as large amounts of work and strict application. |
