ABSTRACT

The purpose of this study is to provide information about technical and fertility characteristics of soils for orchards conversion. Based on satellite images, there were calculate a series of normalized differential indexes resulting from some operations with the spectral bands, meaning they are obtained based on multispectral images (with several spectral bands). Through specific operations, it is aimed to amplify spectral signatures in the band where one particular object has the highest reflectance and diminishing signature of the certain object in the band where it has the lowest reflectance. For preparation of this study, we used data obtained by observation in the field and processed in the laboratory and information’s from images acquired through remote sensing techniques. Satellite methods are used increasingly in current activities, because it makes work easier and can provide fast and accurate solutions based on information gathered space.
