Sažetak
The paper presents the empirical use of height movement kinematic model of Earth’s crust created for territory of the Croatia, Slovenia and Bosnia and Herzegovina, in order to determine the relative height displacements of crust discrete points between different epochs. Also, presents the use of this model for the purpose of direct levelling measurement reductions determination, from surveying epoch to another unambiguously selected epoch, i.e. in purpose of height movement effects elimination from levelling network node benchmarks. For Croatian territory the quality of the kinematic model is indirectly tested, founded on the comparison of levelling measurement accuracy criteria related to the state II order levelling networks constituted with original and reduced levelling measurements. Levelling lines of two levelling networks of the II order, on the area of two deliberately selected and representative levelling loops of the Croatian state levelling network of I order, were analyzed. An accuracy criterion, using the original measurements and comparatively using the reduced measurements from their survey epoch to the I order network surveying epoch, is determined. Comparative comparison of the original and reduced measurement accuracy criteria is not clearly and unequivocally confirmed, nor completely rejected, the adequacy of the kinematic model quality for measurement reductions determination. However, comparison points to the fact that the quality of the kinematic model enables reliable determination of the relative height displacements at the centimeter level.
