Extraction and Validation of Biophysical Variables of Grassland Communities Using Fielp Spectroradiometric Measurements

Ground spectroradiometric measurements using a GER3700 spectroradiometer on grassland communities are used to assess the potential of unmixing methods, derivative spectroscopy, and spectral feature fitting. The reference testsite used for this work is a well controlled and maintained area by a multinational biodiversity project, namely ’BIODEPTH’. Results of the application of the different methods are discussed in order to retrieve vegetation cover and nitrogen content.
