#### Determination of geopotential value W 0 L at Polish tide gauges from GNSS data and geoid model

Results of three campaigns of Baltic Sea Level Project and further studies reveal the GPS and spirit levelling data possibly contain errors which affect SST and $W_{0}^{L}$ computations. For that reason, the old data were revised and additionally, in spring 2015, the new GNNS campaign was carried out at tide gauges in Swinoujscie, Ustka and Wladyslawowo. The study concerns ...

#### Accuracy of the Hodges–Lehmann estimates computed by applying Monte Carlo simulations

The paper concerns assessing the accuracy of some variants of robust R-estimates, namely the Hodges–Lehmann estimates, which can be applied, for example, in deformation analyses. Such estimates are robust against outlying observations and in some cases they are a good alternative for more conventional methods of estimation, for example, in testing stability of the potential ...

#### Relation between benchmark displacement velocity and seismic activity caused by underground longwall exploitation

The following paper addresses the problem of mining-induced surface subsidence by giving consideration to the aspect of displacement velocity and its relation to seismic activities recorded in the area of benchmarks. A series of geodetic measurements were carried out in order to develop an accurate description of the deformation process. The mathematical model of a benchmark ...

#### Efficiency of artificial neural networks in map of total electron content over Iran

Maps of the total electron content (TEC) of the ionosphere can be reconstructed using data extracted from global positioning system (GPS) signals. For historic and other sparse data sets, the reconstruction of TEC images is often performed using multivariate interpolation techniques. In this paper, a quantitative comparison of the ability of artificial neural networks (ANN), ...

#### Study on spatial distribution of horizontal geodetic control points in rural areas

The paper presents the results of research concerning the analysis of spatial distribution of detailed geodetic control points in rural areas in Poland. The analysis takes into consideration the relations between the number of geodetic control points and land cover type (built-up, agricultural, and forest) as well as the effective legal regulations in Poland with regard to the ...

#### Publishing globes on the internet

This paper presents possible solutions to the problem of interactive digital globe publishing on the Internet in connection with the recently opened Virtual Globes Museum. It describes the processing method of two possible source materials: globe prints and photographs. The visualization of the results is realized in two different ways. The first one is a 3D virtual world created ...

#### Mosaicking of the 1:75 000 sheets of the Third Military Survey of the Habsburg Empire

The original map sheets of the Third Military Survey of the Austro-Hungarian Monarchy cannot be mosaicked in their original, printed form because of their uneven trapezoid format. To make a digitized raster mosaic of the individual sheets, they all should be georeferenced. Instead of the original projections, which vary from sheet to sheet, a series of sinusoid projections was ...

#### Hungarian national report on IAG 2007–2010

In sum, the following activities were done: a) the IAG website was updated, improved and continuously maintained b) the IAG Newsletter was regularly issued monthly and distributed electronically, and selected parts of them were prepared to publish in the Journal of Geodesy as IAG News c) new version of the IAG Leaflet was prepared, printed and distributed at different IAG meetings ...

#### Rediscovering the old treasures of cartography — What an almost 500-year-old map can tell to a geoscientist

Tabula Hungariae (1528), created by Lazarus (Secretarius), is an almost 500 year-old map depicting the whole Pannonian Basin. It has been used for several geographic and regional science studies because of its highly valued information context. From geoscientific point of view this information can also be evaluated. In this contribution an attempt is made to analyse in some extent ...

#### Cartometric analysis of the Czechoslovak version of 1:75 000 scale sheets of the Third Military Survey (1918–1956)

The 1:75 000 scale Special Map (SM75) series of the Third Military Survey is analysed in this work. Geographic co-ordinates of the sheet corners are computed from the sheet number codes, as well as their grid co-ordinates in the modern Křovák Projection and Czech and Slovak national grid called S-JTSK. Distortions caused by paper drying and shrinkage were analysed and a ...

#### Horizontal control for stable cadastre and Second Military Survey (Franziszeische Landesaufnahme) in Bohemia, Moravia And Silesia

The paper deals about significant projects of large scale mapping at the beginning of 19th century in the Habsburg Empire. They have been already based on uniform geodetic horizontal control. Basic parameters and features of Second Military Survey in the territory of the Czech Lands as well as links with project of Stable cadastre are delineated. Technology of establishing the ...

#### Georeferencing the first bathymetric maps of Lake Balaton, Hungary

Lake Balaton is located in the Pannonian Basin, Hungary (46°50′ N, 17°50′ E), and is characterized by its large area (594 km2) and very shallow water depth (avg. 3.5 meters). The main tributary is the Zala River, which enters the western bay, and the only outlet is the Sió River in the East. Sámuel Krieger conducted the first known survey focusing on Lake Balaton in 1776. The ...

#### Georeferencing and quality assessment of Josephine survey maps for the mountainous region in the Triglav National Park

Various spatial data sets of high quality and homogeneity allow a higher level of multidisciplinary research. The study is aimed at providing a clearer understanding of the technical and semantic aspects of the quality of historical maps, especially with respect to positional errors, through the georeferencing process. Georeferencing the system of historical map sheets with high ...
