A three dimensional geodetic network model for the analysis of localised earth deformation.

Abstract

Mathematical models, within the framework of integrated geodetic networks, for localised threedimensional geodetic monitoring networks are presented. The formulation of the mathematical models is based on the kinematic estimation model of geodetic network adjustment. The geodetic observables considered are astronomic latitudes, astronomic longitudes, astronomic azimuths, vertical angles, horizontal directions, spatial distances, gravity intensities, gravity potentials, gravity intensity differences and gravity potential differences. The basic parameters derived from the adjustment are network coordinates, network point velocities and network point accelerations of the object points. A numerical example is given to illustrate the application of the proposed method.
