Mathematical modelling and design of a three-dimensional geodetic network for localised earth deformation

Abstract

Mathematical model is , within the framework of integrated geodetic networks for localised three dimensional geodetic monitoring networks are presented. The network design aspects has also been considered. The development of these mathematical models was based on the kinematic estimation model of geodetic network adjustment using the inte rated geodetic approach. The network design aspect considered was the weight problem for each of the various observables used. These observab es were astrol omi~ latitude, astronomic longitude, astronomic azimuth, ve r t ic a i angles, horizontal directions, spatial distances, differences and gravity potentia differences. parameters computed were the network coordinates the point velocities and acceleration& of the unstable points
