“…The data from the old gravimetric survey performed by the former SFRY reach into the 1950s. This dataset was analyzed and transformed (from the original Gauss Kruger coordinates (Bessel ellipsoid) into the ETRS89 Transversal Mercator (GRS80 ellipsoid)) using the national triangular transformation, version 3.0 [15], already in the process of calculating the new quasi-geoid. Figure 2a shows the old gravimetric data of the former SFRY for the territory of Slovenia and a part of Croatia, which are at our disposal, in blue dots.…”

The existing Bouguer anomaly map, which covers the territory of the Republic of Slovenia is a few decades old. Since then, quite a few new gravimetric measurements (data) for the territory of Slovenia as well as high quality digital terrain models that are needed for creating such a map have been made available. The methodology and standards for creating gravity anomaly maps are also changing. Thus, the national Bouguer anomaly map was updated. There were some gross errors detected in the set of old gravimetric data. Additionally, the influence of new updated gravimetric data was analyzed. The comparison of the various maps and the analysis of the influence of input gravimetric data indicates that the new gravimetric data of Slovenia has a significant influence on the creation of the gravimetric anomaly maps for Slovenia (even over 30 mGals at some points).

“…NVN (v začetku sedemdesetih let) in mrežo I. reda (po letu 1989). Glede na ocenjene hitrosti vertikalnih premikov na območju Slovenije (geodinamika) lahko razlike višin točk zgolj zaradi časovne raznovrstnosti opazovanj na nekaterih območjih znašajo tudi do 10 centimetrov (Koler in sod., 2007 (Berk in Komadina, 2013). Model transformacije temelji na nizu 899 virtualnih veznih točk, ki tvorijo 1776 Delaunayjevih trikotnikov.…”

UVODAerolasersko skeniranje (v nadaljevanju: ALS), v tuji literaturi imenovano airborne laser scanning (ALS) oziroma aero lidar, je metoda daljinskega zaznavanja, ki je v dobrih dveh desetletjih, kolikor so na trgu komercialni sistemi, postala najtočnejša metoda daljinskega zajema podatkov o zemeljskem površju (Liu, 2008). Aerolasersko skeniranje je vedno bolj uveljavljen način za zajem podatkov za tvorbo kakovostnega digitalnega modela višin (v nadaljevanju: DMV), ki je primeren tudi za najzahtevnejše uporabnike.Kakovost DMV, ki ga lahko delimo na digitalni model reliefa (v nadaljevanju: DMR) in digitalni model površja (v nadaljevanju: DMP), je še posebej pomembna pri upravljanju voda.

The article describes the procedure for transformation between old and new horizontal geodetic datum in Bosnia and Herzegovina. Two triangle-based methods were used for transformation, which are based on irregular and regular triangular network. For development of transformation models two set of points were used, one for developing models (around 1200 points), and other for testing (around 850 points). Prior to development, all points were tested at presence of outliers, and outliers are marked in the points database. Results shows that large part of distortions in old triangulation network can be modeled with used methods. Maximal positional standard deviations with best model are 4.5 and 6.4 cm for two sets of points, respectively, while maximal positional discripencies are 30 and 40 cm for two sets of points. Each method has some advantages and disadvantages which are shown in this article. It is shown that the number, spatial distribution and quality of input data are crucial for development of highly accurate transformation model. Also, as an important contribution of this work, some problematic areas with irregular distortions are identified. Finally, some recommendations are given for improvement of developed models.
