Spectral mapping of soil organic carbon

Spectral mapping of soil organic carbonThis chapter first reviews recent pilot studies covering limited areas often with exposed bare soils. Then we focus on the challenges for large scale application of spectral mapping when the soil and parent material are heterogeneous and surface conditions are unknown. In order to deal with these constraints we discuss i) calibration of spectral models based on large spectral libraries, ii) surface conditions that disturb the soil signal, and iii)
