GEODESIA E MODELLI DI GEOFISICA

Provide knowledge and skills in the field of geodesy with particular reference to satellite and terrestrial geodetic measurements, and to gravimetric measurements. The physical knowledge necessary for the study of ground deformations in a tectonic and volcanic environment, and for the modeling of the relative sources will also be provided.

Face to face.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Introduction: definition, objectives and history of geodesy.

Reference systems: basic units, time reference systems, space reference systems, celestial, terrestrial and local reference systems, datum transformation.

Earth shape: introductory concepts, gravity, geoid, ellipsoid, height systems, temporal variations of gravity.

Methods of measurement: atmospheric refraction, satellite observations, geodetic astronomy, gravimetry, terrestrial geodetic measurements.

Projections: overview, cylindrical, planar, conic, Tissot's indicatrix, projection parameters, most common projections, how to choose a map.

Structure and dynamics of the Earth: the geophysical Earth model, isostasy, plate tectonics, interpretation on the gravity field, geodesy and recent geodynamics.

Models of ground deformation sources: point source, pipes, spheroidal pressure sources, tensile dislocations, shear dislocations.
