The design of geodetic deformation monitoring schemes requires decisions to be made regarding the optimal location, density, and accuracy of geodetic sensors and targets. All too often, however, the location of the instruments and accuracy of monitoring are decided upon without regard for the expected location and magnitude of the maximum deformations of the monitored object. This can lead to incorrect interpretations of the behavior of the investigated object. A more rigorous approach is to use deterministic (a-priori) modeling of expected displacements derived from the knowledge of the geometry of the object and its environment, causative factors (loads), properties of the material, and physical laws governing the stress-strain relationship. In order to demonstrate how deterministic modeling can be used to design a geodetic scheme for deformation monitoring, an open pit mine scenario was investigated. Finite element analysis was applied to the open pit mine to obtain a prediction model of deformations at various stages of the mine development.
