摘要
应用非线性插值法对FY-2C静止气象卫星数据中提供的简化网格数据进行近似插值计算。从计算结果看,使用非线性插值法对延时云图的校正效果较为理想,像点定位后扫描列的形状为一条平滑的曲线,基本实现了风云二数据的图像定位,为遥感数据的参数反演和针对性分析做了铺垫。
A method of using the Nonlinear Interpolation to calculate the simplified grid data, which is offered by the FY-2C meteorological satellite,was put forward. The experimental results showed that this approach is effective to correct the delay cloud picture, the row of satellite scan is a smooth curve, and it is effective to find the target of the remote sensing data. The approach provides a foundation of parameter inversion and pointed analysis of the remote sensing data.
