Abstract:

the aim of this study was to characterize and compare the spectral behavior of different soil classes obtained by orbital and terrestrial sensors. for this, an area of 184 ha in rafard (sp) brazil was staked on a regular grid of 100x100 m and soil samples were collected and georeferenced. after that, soil spectral curves were obtained with iris sensor and the sample points were overlaid at landsat and aster images for spectral data collection. the soil samples were classified and mean soil curves for all sensors were generated by soil classes. the soil classes were differentiated by texture, organic matter and total iron for all sensors studied, the orbital sensors despite the lower spectral resolution, maintained the characteristics of the soil and the curves of reflectance intensity.
