摘要：

A procedure of calculation and experimentation addressed to a DTM extraction by TLS data has been implemented. The validation of elevation values has been realized by integrating the data collected with classical topographical and GPS observations. The results obtained allowed the assessment of the appropriate and simplified procedure for the determination of the DTM using laser technology and the possibility to improve and verify the attainable accuracy of the altitude plane. The experimental outputs have been compared with those produced by commercial software. The difference obtained is primarily concerned with the conceptual scheme applied in the definition of the grid in the algorithm of interpolation and obtainable accuracy. Moreover, after obtaining the grid by topographic survey, characterized by a high precision, it is possible to verify its accuracy.
