The objectives of this work are to detect soils through satellite images in continuous areas, allowing their spatialization. To do so, we have as secondary objectives: to choose reflectance spectra of the regions of Brazil, in Vis-Nir-MID on a database; determine a mosaic of soil exposure through satellite images. Syringe obtained on reflectors with laboratory sensors. As pictures translation of Landsat. The soil is continuous, continuously exposed so as to be able to visualize as soil cores as well as other attributes in a concatenated way, facilitating the mapping.
