成像光谱技术及其在土地动态监测中的应用

20世纪80年代出现并于20世纪90年代蓬勃兴起的成像光谱遥感技术已经受到国内外学术界的广泛重视,代表了遥感定量化的发展方向。成像光谱技术提供的连续窄波段成像技术,使它在地质填图、精细农业、资源调查等定量遥感应用中具有极大的潜力。土地动态监测是土地管理工作中的重要环节,研究成像光谱技术在土地动态监测中的应用具有十分重要的意义。本文介绍了成像光谱技术及其在土地动态监测中的应用,并对利用成像光谱技术进行土地动态监测的关键技术进行了阐述。

Imaging Spectrometry and its Application in Land Dynamic Monitoring

Imaging Spectrometry which first appeared in 1980's and boomed in 1990's, had been the focus of the community of scholars. It represents the direction of development of remote sensing. It provided the technology of imaging over the narrow spectral bands,which gives imaging spectrometry great potential in many fields, such as geological mapping, precision agriculture, and resource investigation. Land dynamic monitoring is a key part of land management. Thus it is very important to study the application of imaging spectrometry in land dynamic monitoring. This paper introduces imaging spectrometry and its application in land dynamic monitoring, and discusses the key techniques of using imaging spectrometry in land dynamic monitoring.
