In this paper, the historical development context of the trigonometric network point types in Slovenia from 1810 onwards is presented. Examples of different trigonometric point types still seen in the field are shown, with regard to the institution that carried out the field marking of the specific state trigonometric network. The city trigonometric network of Ljubljana, which was established in 1955–1956, is also presented. Furthermore, triangulation and comparator bases are mentioned as well, which remain marked with permanent pillars. As examples of the oldest still-standing trigonometric points, the following are mentioned: 303 Veliki Javornik (2nd order) with the engraved year 1823 and 329 Limberk (2nd order) with the engraved year 1903.
在本文中，从1810年起，在斯洛文尼亚的三角网络点类型的历史发展背景提出。针对实施特定状态三角网络现场标记的机构，给出了在现场仍然可以看到的不同三角点类型的示例。并介绍了1955-1956年建立的卢布尔雅那城市三角网。此外，还提到了三角测量和比较器基地，这些基地仍然用永久性支柱作标记。作为现存最古老的三角点的例子，下面提到:303 Veliki Javornik(二级)，刻着1823年，329 Limberk(二级)，刻着1903年。

Up-to-date cadastral maps are crucial for urban planning. Creating those maps with the classical geodetic methods is expensive and time-consuming. Emerge of Unmanned Aerial Vehicles (UAV) made a possibility for quick acquisition of data with much more details than it was possible before. The topic of the research refers to the challenges of automatic extraction of building footprints on high-resolution orthophotos. The objectives of this study were as follows: (1) to test the possibility of using different publicly available datasets (Tanzania, AIRS and Inria) for neural network training and then test the generalisation capability of the model on the Area Of Interest (AOI); (2) to evaluate the effect of the normalised digital surface model (nDSM) on the results of neural network training and implementation. Evaluation of the results shown that the models trained on the Tanzania (IoU 36.4%), AIRS (IoU 64.4%) and Inria (IoU 7.4%) datasets doesn't satisfy the requested accuracy to update cadastral maps in study area. Much better results are achieved in the second part of the study, where the training of the neural network was done on tiles (256x256) of the orthophoto of AOI created from data acquired using UAV. A combination of RGB orthophoto with nDSM resulted in a 2% increase of IoU, achieving the final IoU of over 90%.

Then we processed time-series data of two GNSS station coordinates during 5 earthquakes that occurred near SRVJ and BEOG stations and estimated spectral indices of power-law noise from postfit residuals after removing linear, annual and semi-annual variation in the MODELLING THE OF GNSS COORDINATES AND THEIR INTERACTION WITH AVERAGE MAGNITUDE (27.71 mm/year). Estimated horizontal components have smaller deviations than the vertical part. The Weighted Root Mean Square (WRMS) error estimation of a function for one year for coordinates and deformations is 2.31 mm for the horizontal component and 5.36 mm for the height component. This study shows that there are seasonal and semi-annual signals in all three coordinate components. It can be seen that the periodic components are different for the analyzed BEOG station. Also, the annual period is dominant. Annual variation is with typical amplitudes about 1 mm for horizontal and over 2 mm for vertical.

The coordinate transformation has always been a hot topic in the field of geodesy. The artificial neural network (ANN) has been used as an alternative tool to determine the relationship between any two coordinate systems. Construction of an effective neural network depends on the network architecture, learning parameters and normalization technique used. Finding the best data normalization technique is an important step when designing a neural network. This study investigated the performances of eight normalization techniques on two-dimensional (2D) coordinate transformation using a generalized regression neural network (GRNN). The methods examined included the maximize, min-max, median, median-median absolute deviation (median-MAD), mean-mean absolute deviation (mean-MAD), statistical column, tanh, and z-score.
