上海边滩资源彩红外遥感影像分析应用

海塘滩涂信息的研究在水利工程建设、海塘管理、滩涂围垦、防洪抢险等许多领域具有广泛的应用价值。本文利用彩红外航片通过一系列处理对上海市的边滩资源进行了提取,运用监督分类与目视判读相结合的方法进行解译分析,并对分类结果进行野外核实与修正,为海塘滩涂部门的管理提供了有效的技术支持,提高了所获取数据的精度和工作效率。

Extraction of Color Infrared Remote Sensing Images to Study Tidal Flat of Shanghai

Researches on the information of seawall and tidal flat have extensive prospect for application in many fields of hydraulic engineering construction,seawall management,tidal flat reclamation,flood fighting and so on.The tidal flat in Shanghai was extracted from the remote sensing images in this paper.After a series of processing procedures on color infrared aerial photographs,the information on the tidal flat was interpreted and analyzed using the method which combines the supervised classification with visual interpretation from the remote sensing images.The classified results were checked and revised based on the field investigation.It has provided an effective technical support for the tidal flat and foreshore department's management,greatly enhancing the accuracy of the data acquisition and the work efficiency.
