    Geodetic Observations at the Eolian Islands (Southern Italy) (2008)
    Edizioni - Nautilus
    Details
    Publication Date: 2017-04-04
    Description: In order to investigate the dynamic processes actually in progress in the Aeolian Islands a volcanic area in Southern Italy, high precision geodetic observations are employed. the knowledge of the kinematic field (vertical and horizontal displacements) and of the time-space gravity variations is an important constrain for any model describing the geodynamic processes involving the investigated area. Gravimetric (absolute, relative and gradiometric), photogrammetric, altimetric and GPS surveys are periodically carried out on networks spanning over the whole aeolian archipelagus. Recently a GPS network has been designed and surveyed to obtain a more complete knowledge of the kinematic field taking place in the area. This will improve the understanding of the tectonic processes acting in the area. The result of the interdisplinary approach are presented and discussed.

    Comparison between leveling-gps heights and Italian gravimetric Geoid (2008)
    Edizioni - Nautilus
    Details
    Publication Date: 2017-04-04
    Description: The recent development of the Global Positioning System geodetic technique allow the determination of the separation between the ellipsoid and the geoid if GPS-derived elevations are compared with spirit leveling measurements; this approach may provide a contribution to the definition of the geoidal ondulation even on areas such as the Italian peninsula characterized by wide roughness of topography and very complex geological and structural features. With this aim in 1993 we measured by the GPS technique the position of 32 benchmarks along some of the Italian first order leveling routes located across the Apenninic chain. The simultaneous surveys performed on ITRF stations and on 5 tide gauge stations, may provide an accurate constrain of the gravimetric geoid recently computed by DIIAR in Milan, Italy.
