The paper describes the problem of conversion of heights to the European Vertical Reference Frame 2007 for Poland (PL-EVRF2007-NH). The subject of the study is height data, and especially the detailed vertical reference network. The aim of the article is to present an alternative method of conversion to the one recommended by the Polish Head Office of Geodesy and Cartography. The proposed approach is characterised by a low implementation cost while maintaining the required accuracy.The publication is illustrated by the case of Kętrzyn district (in the north-east part of Poland). The local reference network was converted from Kronstad’60 to PL-EVRF2007-NH in 2017.

“…Poland has two normal vertical frames based on a quasi-geoid: one with zero point in Amsterdam (PL-EVRF2007-NH), and the second in Kronstadt (PL-KRON86-NH) [97]. The differences among these data change irregularly, from 12 cm to 20 cm, depending on the area [98]. Thus, for the remainder of the text, the authors will refer to the normal height system only, and its practical realization-the PL-KRON86-NH.…”

Determining the correct height of mountain peaks is vital for tourism, but it is also important as a reference point for devices equipped with GPS (Global Positioning System), e.g., watches or car navigation systems. The peak altitude data are part of geographic and geodetic information. As more modern technologies and equipment become available, their precisions should increase. However, verification of peak heights is usually only conducted for the highest, well-known mountains—lower peaks or mountain passes are rarely verified. Therefore, this study focuses on an investigation of 12 altitude points on a section of the longest and most famous touristic trail in Poland (the Main Beskid Trail), located in the Orava–Żywiec Beskids Mts (Mountains). The aim of this research is to measure and verify the heights of the 12 selected mountain peaks, in addition to evaluating the chosen methods based on the quality of the obtained data and determining their suitability and opportunities for use in further research. Measurements were obtained at the most specific height points—on the 12 highest points of the summits. This study compares two modern measurement techniques: the global navigation satellite system (GNSS) and light detection and ranging (LiDAR). The obtained results were later compared with those widely used on the internet and in printed materials (period covered: 1884–2015). This analysis demonstrates that lesser-known objects are rarely the subject of remeasurement and significant altitude errors may occur, primarily because the heights originated from a source in the past when modern methods were not available. Our findings indicate that the heights of the peaks presented in cartographic materials are inaccurate. The assumed heights should be corrected by direct measurements using modern techniques.

“…environmental impacts that affect the subsidence of vertical control points. Considerations on this subject can be found in the research paper [Borowski, Lal, Nepelski 2017], where the earth marks of the vertical control network were selected for the analysis, as well as in the paper on the implementation of the research programme, which concerned the determination of the operational reliability of the vertical control network [Wolski, Derezińska 2008]. An important contribution for the presented subject describing the status of geodetic network is the publication [Banasik, Ligas, Kudrys, Skorupa, Bujakowski 2012].…”

The final result of surveys largely depends on the accuracy and timeliness of the control network. This research paper presents the relationship between the condition of the points and the area where they are located. The main goal of this study is to present the methodology of a detailed analysis of the database of vertical control points in a selected area that is used to develop a mobile application intended for the update of the existing set of points of the vertical control network on an ongoing basis. In order to prepare the mobile application for the ongoing update of the control network, it is necessary to define detailed procedures for dealing with the database of points. These procedures concern the determination of the methodology of making an inventory of the existing database, and then the determination of the rules for updating the control network using the developed application.
