基于水体时空稳定特性的辐射一致性校正方法

Research on radiation consistency correction method based on spatial and temporal stability properties of water bodies

以太湖32个监测站点的监测数据为依据,通过分析水环境关键因子的稳定性,进行水体稳定特性筛选,并以Landsat 8和Sentinel 2数据为例,综合水体稳定特性,进行多源遥感数据辐射一致性校正研究。研究实现了深蓝、蓝光、绿光、红光、近红外这5个波段的辐射一致性校正,为多源遥感数据的辐射一致性校正方法提供了思路。

Based on the monitoring data of 32 monitoring stations in Taihu Lake,the stability characteristics of water body are screened by analyzing the stability of key factors of water environment.Then,taking Landsat8 and Sentinel2 data as examples,the radiation consistency correction of multi-source remote sensing data is carried out by integrating the stability characteristics of water body.In this study,the radiation consistency correction of the five bands of deep blue,blue light,green light,red light and near infrared is finally realized,which provides ideas for the radiation consistency correction method of multi-source remote sensing data.
