Hyperspectral Imagery: A New Tool For Wetlands Monitoring/Analyses
ثبت نشده
چکیده
PURPOSE: This technical note demribea the spectral and spatial characteristics of hyperspectral data and the potential application of these data for wetlands studi~ and monitoring applications. The advantages and disadvantages of these data for wetland evaluations are discussed. Spectral signatures extracted tim data squired by NASA’s collected Airborne Visible/Infked Imagery Spectrometer (AVIRIS) hyperspectral scanning over a wetland study site are analyzed.

Land Cover Subpixel Change Detection using Hyperspectral Images Based on Spectral Unmixing and Post-processing
The earth is continually being influenced by some actions such as flood, tornado and human artificial activities. This process causes the changes in land cover type. Thus, for optimal management of the use of resources, it is necessary to be aware of these changes. Today’s remote sensing plays key role in geology and environmental monitoring by its high resolution, wide covering and low cost...

Hyperspectral data in Remote Sensing which have been gathered with efficient spectral resolution (about 10 nanometer) contain a plethora of spectral bands (roughly 200 bands). Since precious information about the spectral features of target materials can be extracted from these data, they have been used exclusively in hyperspectral target detection. One of the problem associated with the detect...
