Furthermore, deformation measures, such as expansions, shearing strains and rotations in the infinitesimal environment of the points can be calculated. The main problem consists in the implementation of a continuous body from geodetic measurements at discrete points, in order to be able to apply the theories of continuum mechanics. Therefore, one focus is put on the theoretical description of the kinematics of the continuum as well as on the theoretical discussion of some interpolation methods, which are suitable for a solution of the problem. In particular, monomials, Bernstein polynomials as well as the generalized Bernstein polynomials as basis functions for the interpolation with bivariate polynomials, tensor product Bezier surfaces as well as triangle Bezier surfaces are presented and compared. The theoretical considerations are tested with example data records of the rock glacier Macun I. The results of the modelling of the continuum are presented in form of concrete numerical values and diagrams and are discussed. Suggestions on refined basic approaches for the model on the basis of new realizations are developed and interfaces for the extension of the models in order to allow the integration of additional hybrid data are pointed out. Beyond that, possibilities are presented for a transition of the used kinematic models to the dynamic models.
