The paper presents a new methodology for high precision deformations monitoring in the long term perspective using terrestrial laser scanning technology. In order to solve the problem of a stable reference system and quality of possible position changes of point clouds, scanning is integrated with two surveying techniques, i.e. high quality static GNSS positioning and precise tacheometry. The case study object is a high pressure underground pipeline situated in an geologically unstable area.

We present solutions for GPS orbit computation from broadcast and precise ephemerides using RBFN. The problem of precise broadcast orbit correction has already been solved using polynomial and trigonometric interpolation. As an alternative RBFN broadcast orbit correction produces results within the accuracy range of interpolation methods. Our study shows RBFN orbit correction performs well also for short data spans. Regarding limitations of polynomial and trigonometric extrapolation, the most significant advantage of using RBFNs arises from its short time prediction capability.

The understanding of the intraplate tectonics of Central Europe requires a detailed picture of how stress is transferred from the interaction of the Eurasian, Nubian and Anatolian plates to the Alpine, Carpathian, Pannonian and Dinaric regions. Recent strain distribution is controlled by the Adria horizontal push, by the Vrancea vertical slab pull and associated horizontal displacements, and by the Aegean/Anatolia extension and slab-roll back. We present a horizontal velocity field for the Alpine-Carpathian-Pannonic-Dinaric and Balkan regions from a new combination of seven GPS networks.

Analytical derivation of a simplified model for a-priori estimation of lidar errors prior to the surveying mission is presented in the paper. This model enables a quick calculation and gives a-priori plausible values for the average and maximum error size, independent of the scan and heading angles as well as being independent of any specific lidar system’s characteristics. As a basis for deriving this model, Schenk's geolocation equation is used. A review of the different error-source sizes is summarized to define the boundary conditions for each error size.

The competences of surveying higher educational programmes have been changing rapidly since the study area is covering the fields of fast developing technology as well as the fields of licensed disciplines. Beside the competences of the surveying engineers in today’s society in general, the renovation and competences of higher study programmes of surveying in Slovenia is presented. The new curricula and competences have considered European and international guidelines in higher education of surveying and geodesy.
