Quantitative analysis of biophysical parameters of crops using multispectral data Copernicus
Mišurec, J. ; Lukeš, Petr ; Tomíček, J. ; Klem, Karel ; Jakešová, L.
The development of a methodology for retrieval of biophysical parameters using multispectral satellite data Sentinel-2 has been optimized for the most frequently grown crops in the Czech Republic: winter wheat, spring barley, oilseed rape, lucerne, maize and sugar beet. The target crop parameters were chlorophyll and water content in leaves and leaf area index (LAI). The method of calculating biophysical parameters was based on the use of the ProSAIL radiation transfer model, where the model simulates canopy status for various combinations of biophysical parameters in inverse mode. A combination of biophysical parameters, showing the best match for the reflectance values observed by the Sentinel-2 satellite system is searched. Developed products will find use in farms, for example in planning the management of agricultural land.
