利用海洋水色卫星 Seastar/SeaWiFS数据和准同步实测表层含沙量资料,建立长江口区悬浮泥沙遥感定量模式.通过“exact closed-form”算法对多时相SeaWiFS数据进行几何定位,并利用大气辐射传输简化理论对其进行大气校正,求得各波段遥感反射率;在完成投影变换和几何精校正之后,建立遥感参数与含沙量相关关系,得到长江口区悬浮泥沙遥感定量模式.
Based on the Seastar / SeaWiFS data of oceanic colorimetry and quasi-synchronously measured surface sediment concentration, the quantitative model of suspended sediment in the Yangtze River estuary was established. Geometrically positioning of the SeaWiFS multi-temporal data by “exact closed-form” After the projection transformation and geometric correction were completed, the correlation between remote sensing parameters and sediment concentration was established, and the remote sensing quantitative model of suspended sediment in the Yangtze River Estuary was obtained.
