航天遥感多源数据的复合信息及其应用研究——以黄河口为例

The Study of Fusion and Applications of Multi-source Data in Spaceborne Remote Sensing ——Taking Huanghe River Estuary for Example

阐述了遥感多源信息复合的理论与技术依据 ,指出TM与SAR影像复合可实现优点的合成 ,旨在丰富地物的特征信息 ,提高目标分类精度 ,特别是有利于对滨海动态的监测与新生地貌体所关联的泥沙输移和海洋动力作用等隐伏信息 ,并以近期黄河口沙嘴演变的遥感影像作为例证。

Along with the exposition of the theory and technique dependence of fusion of multi source data in remote sensing we point out that fusion of TM and SAR will achieve the compound of strongpoint, enrich character information and raise precision of classification. Especially it is propitious to inspection of dynamic shore and insidious information of anagenesis of physiognomy related to bedload transport and ocean dynamical effect. The recent evolution of the sand spit of Huanghe River's mouth is taken for example.
