Potencialidade do sensor Worldview II na detecção de hematita e goethita em solos tropicais

With the advance of techniques and technology, the remote sensing has been a very helpful tool for mapping the soils through the spectroscopy of reflectance. Spectral behavior of the soil it is a term used to define the interactions of the electro-magnetic radiation with the different types of soil and intrinsic factors to them, like the physical-chemical properties. This soil’s specifications control the spectral curves and the properties most studied are organic material, soil texture, color, moisture e iron oxides. This study has been growing since the 80’s and it needs research support to achieve better understanding about the spectral behavior soil. The purpose of this article it has to emphasize the spectral behavior soil according to the many constituents of soil.
