Analyses of spaceborne hyperspectral and directional CHRIS data to deliver crop status for precision agriculture.

CHRIS is the first spaceborne multiangular imaging spectrometer with high spatial resolution. CHRIS data was analyzed to deliver input information for precision agriculture. The reflectance spectra obtained were compared with optical radiative transfer simulation results of SLC, an extended version of the canopy reflectance model GeoSAIL. Directional reflectance spectra are extracted and the directional variations compared to the model results. As results from the optical modelling approach, crop parameters such as LAI and chlorophyll content are retrieved from the CHRIS data and provided as spatial maps. These can be further used for plant production simulations.
