Hyperspectral imaging based techniques in contaminated soils characterization

Contaminated soil characterization represents one of the primary key-factors to evaluate when reclamation strategies have to be designed and applied. Soil characterization are conventionally performed adopting integrated physical-chemical analyses based on soil portion (samples) directly collected in situ. Such an approach is obviously time consuming. In this work is examined the possibility offered by hyperspectral imaging based techniques to perform fast and reliable tests able to identify and quantify specific soil characteristics of primary importance in soil reclamation. The proposed approach, methodologically very simple to apply, for its flexibility could be profitably utilized also for other applications as those linked to agricultural soil monitoring.
