Modelación general de los efectos de la geometría de iluminación-visión en la reflectancia de pastizales

in this study a general model for minimizing the effect that the illumination-vision geometry has on the vegetation reflectance in the red (r) and near infrared (nir) bands was developed and evaluated. in order to validate the proposed model three data bases, obtained in experiments carry out in natural grasslands zones in three different parts of the world, with characteristics so different among them (species composition, vegetal cover percentage, kinds of soils, etc.) were utilized. the results obtained were adequate (r2≥0.98).
