| 摘 要： | 将HY-1BL1B产品中已有的经纬度数据抽样作为控制点,根据控制点的图像坐标和经纬度坐标间的对应关系,基于薄板样条函数的坐标变换关系对HY-1BL1B数据进行了几何校正,并与陆地矢量边界进行了比较,结果表明该方法能较好地完成HY-1B卫星L1B数据的几何校正。

| Abstract: | Using corresponding relationship of image coordinates and latitude and longitude coordinates of control points which sampled from HY-1B L1B product, geometric correction for HY-1B L1B data based on the Thin-plate Spline function coordinate transformation relations is carried out in this study.And the comparison with the land vector boundary has been done.The results show that HY-1B satellite L1B data geometric correction could be done well with this method. |
