【摘要】 高光谱遥感数据具有图像—光谱合一的特点,与传统的多光谱遥感数据相比,能够更好的分类与识别各类地物,本文主要利用高光谱遥感数据,实现海岸带分类,并且在此基础上实现沙滩表面承载特性信息的提取,主要内容分为以下三个部分: 第一部分概要介绍了高光谱遥感技术。首先回顾了高光谱遥感的基本概念、原理和发展历史,然后介绍了高光谱遥感数据的预处理,包括大气校正,几何校正,以及高光谱遥感技术的主要分析方法,最后对试验高光谱数据做了预处理。 第二部分研究高光谱遥感海岸带分类技术。分析了海岸各类地物的光谱特性,并介绍了基本的遥感图像分类算法,在基本的分类算法的基础上,根据海岸带地物光谱特性,设计了海岸带混合决策分类算法,实现海岸带地表覆盖信息的初步分类。 第三部分利用高光谱遥感资料研究海岸带沙滩表面承载特性。对海岸沙滩的光谱影响因素以及沙滩表面承载特性进行了实验分析,并根据实验分析的结论利用高分辨高光谱遥感数据制作了海岸带沙滩表面特性的专题图,最后探讨了高光谱数据在海岸带探测方面应用。更多还原

【Abstract】 Hyperspectral remote sensing data has the characteristic of combining both image data and spectral data into one data set, each pixel of a hyperspectral image an entire spectrum (consisting of numerous contiguous, narrow spectral bands) is present. Compared with conventional multi-spectral remote sensing data, hyperspectral remote sensing data can be more useful for the identification and classification of surface Materials. In this paper, the author classified the coastal area using hyperspectral remote sensing data, and further more, succeeded in extraction of sand beach surface information related to bearing capacity characteristic. This thesis consists of the following three parts.In the first part, the author firstly reviewed hyperspectral technology, include its basic conception, theories and its developing history, then introduced preprocess of hyperspectral data concerning atmospheric correction, geometric correction and its basic analysis techniques. Finally the write preprocessed the hyperspectral data used in this thesis.In the second part, mainly concern with coastal area classification techniques using hyperspectral data. Based on analysis of spectrum features of coastal surface materials and basic classification method, the author proposed a hybrid decision tree classification algorithm and classified the coastal area.In the third part, mainly study on sand beach surface characteristic of bearing capacity by hyperspectral remote sensing data. Based on analysis of field spectrum of sand beach and its surface characteristic, the author made a thematic map, which indicated sand beach surface characteristic of bearing capacity. Final, the author discussed hyperspectral and its applications detecting coastal zone.更多还原
