多光谱水深遥感方法及研究进展

Some Research Advances and Methods on Water-Depth Monitoring by Multispectral Images

文中简单回顾了多光谱水深遥感的国内外研究进展。将当前水深反演模型归为3类:即波浪法、统计法和水体散射遥感测深法,对各模型作了简单介绍,以时间为顺序列出了各模型在实践中的应用状况,分析对比了各种模型的优势和劣势。最后对当前水深遥感的发展趋势谈了自己的两点认识:即高分辨率数据的应用,改进的或新的水深反演方法不断涌现。

This paper briefly reviews the study progress of monitoring water depth by multi-spectral remote sensing. Meanwhile,inversion models are reduced to three types, namely ： wave spectrum bathymetric, statistics model and water column scattering - based remote bathymetric model. It also makes a brief introduction of the models , gives some practical examples ,points out the advantages and disadvantages of various models. FinaUy,the current trend in development of monitoring water depth by remote sensing are summarized ： Firstly, The application of high-resolution and hyperspectral images. Secondly, improved or new inversion methods are emerging.
