                         (Laborat{\'o}rio de Radiometria e Caracteriza{\c{c}}{\~a}o de 
                         Sensores Eletro{\'o}pticos), which is a device capable to measure 
                         the spectral Bidirectional Reflection Distribution function (BRDF) 
                         and the emissivity of usual materials in remote sensing 
                         researches. The goniometer was projected to be used with a light 
                         source and a spectroradiometer, consisting in a electro mechanic 
                         assemble. The device structure is subdivided in: a sensor arc; a 
                         light source-supporting arc; a ring and a sample holder, each one 
                         attached to automated motors. In a default setup, the distances 
                         from the sample, with 30 cm maximum diameter, to the sensor and 
                         the light source are 100 cm and 120 cm, respectively. Radiometric 
                         data, necessary to estimate the BRDF, may be collected either in 
                         automatic mode, by the automated control of the motors, or in 
                         manual mode by an operator. In automatic mode, a typical BRDF data 
                         collection, concerning to 15 degrees of resolution in the angular 
                         positioning of all structures, takes approximately 60 hours 
                         involving all possible geometries. We also present the first 
                         characterization of a surface, using a reference panel, with the 
                         objective to verify the azimuthal and zenithal angular 
                         configurations in which construction issues would induce shadow 
                         casting on the sample.",
