Integrazione di rilievi batimetrici e laser scanner aereo nell'area dei Colli Albani

The Colli Albani are a Quaternary volcanic complex located about 15 km SE of Rome, comprised
in an area of latitudes 41.6-41.9 N and longitudes 12.5-12.9 E. It has recently developed particular
interest in the geophysical community for some peculiar characteristics imputable to a residual
volcanic activity.
In the framework of a project financed by the Department of the Civil Protection devoted to the
study of the Colli Albani deformations, we have recently realized a bathymetric survey of the
Albano lake and an airborne laser scanner survey of the Albano and Nemi craters.
The present work is composed by two phases. In a first phase the accuracy of the DEM achieved by
the laser scanner is verified through a comparison with a GPS kinematic survey. In particular, our
aim is to test if the use of DEM in different formats, TIN or Grid, could lead to meaningful
differences in terms of accuracy and precision. In a second phase of the work, we merged the
LIDAR and bathymetric data with the purpose to achieve a complete digital terrain model of the
area that could allow in the next future geo-morphological analyses of the whole volcanic structure.
