In this paper we present the creation of a national height transformation model that allows the transformation of heights between the old (SVS2000/Trieste) and the new height system (SVS2010/Koper) and vice versa. The height transformation surface - SLO-VTP2024 was created on the basis of 2,116 height differences between the old and the new height system on benchmarks evenly distributed across Slovenia. The height transformation surface - SLO-VTP2024 and SLO-VTP2024 accuracy surface is determined by the kriging interpolation method with additional influence of the variogram and written in the form of a cell grid. The ViTra software package is presented, which enables the height transformation on the basis of optimized bilinear interpolation equations. The quality of SLO-VTP2024 was assessed on the basis of the differences between the calculated heights and the heights determined by the transformation at the points for determining the height transformation surface – 2,116 benchmarks, at 8,775 and 8,695 control benchmarks, on control benchmarks belonging to different orders of the levelling network, on control benchmarks stabilized in individual loops of the new 1st order Slovenian levelling network, and by area and benchmarks stabilized in individual city levelling networks.

Abstract

V prispevku predstavljamo vzpostavitev državnega višinskega transformacijskega modela, ki omogoča transformacijo višin med starim (SVS2000/Trst) in novim višinskim sistemom (SVS2010/Koper) in obratno. Višinska transformacijska ploskev SLO-VTP2024 je bila izdelana na podlagi 2116 razlik višin med starim in novim višinskim sistemom na reperjih, ki so enakomerno porazdeljeni po območju Slovenije. Višinska transformacijska ploskev SLO-VTP2024 in ploskev natančnosti SLO-VTP2024 sta določeni z interpolacijsko metodo kriging z dodanim vplivom na variogramu in zapisani v obliki celične mreže. Predstavljen je programski paket ViTra, ki omogoča transformacijo višin na podlagi optimiziranih enačb bilinearne interpolacije. Kakovost SLO-VTP2024 smo ocenili na podlagi razlik med preračunanimi višinami in višinami, določenimi s transformacijo na točkah za določitev višinske transformacijske ploskve – 2116 reperjev, na 8775 oziroma 8695 kontrolnih reperjih, na reperjih posameznih redov nivelmanske mreže, na kontrolnih reperjih, ki so stabilizirani v posameznih zankah nove nivelmanske mreže 1. reda Slovenije in po območjih in na reperjih, ki so stabilizirani v posameznih mestnih nivelmanskih mrežah.
