Further researches will be addressed to the use of integrated attributes (meta-attributes) to further improve the autopicking algorithm. Acknowledgements.

Fig. 2 - 3D visualization of underground utilities obtained by semi-automatic procedure applied on first derivative attribute. In addition to the geometry and depth variations of the underground utilities, it is possible to note their intersections.
