GERAÇÃO DE MODELO DIGITAL DE TERRENO POR MEIO DA FILTRAGEM DE DADOS OBTIDOS POR VARREDURA A LASER UTILIZANDO UM MÉTODO BASEADO NO PRINCÍPIO DA DECLIVIDADE

Due the advances in the technology of laser scanning\udsystems, research in several countries have been initiated with the aim of\udexploring the recently technological resources developed. The result\udobtained by laser scanning systems provided the details of regions\udfeatures and update many of the national territories models. The data\udgenerated by laser scanning match the altimetry data set named as Digital\udElevation Model. This model derivation, when containing only terrain\udfeatures, is called Digital Terrain Model. However, the Digital Terrain\udModels cannot be easily generated by laser scanning. In general, the\udDigital Terrain Models are derived from Digital Elevation Models applying\udfiltering methods. This work objective is to adapt a Digital Elevation\udModel filtering method and discuss the results obtained
