Research Advances of Hyperspectral Remote Sensing in vegetation Monitoring in the Three Gorges Reservoir Area
Abstract:Hyperspectral remote sensing technology is an advancing technology of Remote Sensing in the next decades. It has the special qualities of high spectral resolution and plentiful data etc, so it can be extensively applied in riparian vegetation monitoring in recent years. In this paper, the advantages of the hyperspectral remote sensing in vegetation monitoring and various influence factors from the vegetation are summarized. The application of hyperspectral remote sensing in vegetation monitoring, species identification and yield estimation is mainly discussed. The general processing methods and algorithms are presented. In the end, the special habitat of vegetation in the Three Gorges Reservoir Area and problems of hyperspectral remote sensing are discussed, and the development trend on the hyperspectral remote sensing is forecast.
Keywords: Hyperspectral remote sensing Vegetation Three Gorges Reservoir Area
