             abstract = "The Reflectance spectroradiometry is a technique of remote sensing 
                         that allows obtaining spectral data of the soil through the use of 
                         hyperspectral sensors. A database with information on spectral 
                         curves of soils can contribute to understanding the physical, 
                         chemical and mineralogical properties of this non-renewable 
                         resource that enables terrestrial life. For this, the construction 
                         of a regional spectral library becomes of great utility. The 
                         objective of this study was to analyze and characterize the 
                         spectral behavior of soil samples from the Sisal region. Spectral 
                         data were collected (using a Field Spec sensor, 350-2200nm) for 
                         soil samples at depth of 20cm, from the municipality of 
                         Santaluz-BA. The samples were sieved in a 2mm mesh to homogenize 
                         their roughness and humidity effects, and dried in an stove at 
                         45ºC, in a period of 24 hours. Then, the radiometric analysis and 
                         interpretation of the results were done, each sample being 
                         represented by a single spectral curve plot. The reflectance curve 
                         was influenced mainly by iron oxides, smectite and organic matter. 
                         The main difference in the curves of the four samples analyzed was 
                         the change in reflectance intensity. The use of an innovative 
                         technique of soil studies proved to be efficient, fast and 
                         ef-fective for the understanding of soil composition, generating 
                         data that may contribute to the Spectral library of soils of the 
                         Sisal region.",
