High-Order Derivative Spectroscopy For Selecting Spectral Regions And Channels For Remote Sensing Algorithm Development, Charles R. Bostater
High-Order Derivative Spectroscopy For Selecting Spectral Regions And Channels For Remote Sensing Algorithm Development, Charles R. Bostater
Ocean Engineering and Marine Sciences Faculty Publications
A remote sensing reflectance model, which describes the transfer of irradiant light within a plant canopy or water column has previously been used to simulate the nadir viewing reflectance of vegetation canopies and leaves under solar induced or an artificial light ur'2 and the water surface reflectance3' Wavelength dependent features such as canopy reflectance leafabsorption and canopy bottom reflectance as well as water absorption and water bottom reflectance have been used to simulate or generate synthetic canopy and water surface reflectance signatures3' ' This paper describes how derivative spectroscopy can be utilized to invert the synthetic or modeled as well …

The practical application of current airborne and future satellite or space station based high spectral resolution (hyperspectral) imagery to vegetative canopies (sparse or dense) and resulting derived bio-physical variables will depend upon our ability to rapidly apply scientifically based algorithms. Key to these rapid assessments is the selection ofthe best or optimal channels or bands for detection of plant stress or dysfunction. Previous work '2,3,4,5 has demonstrated the potential of utilizing high spectral resolution optical signatures for detecting plant stress related to the vegetation's moisture within the leaf structure. Future algorithms and techniques need to discriminate plant species as well …
