Article
Tide gauge observations provide sea level relative to the Earth’s crust, while satellite altimetry measures sea level variations relative to the centre of the Earth’s mass. Local vertical land motion can be a significant contribution to the measured sea level change.Satellite altimetry was traditionally used to study the open ocean, but this techno...

The main aim of the article was to analyse the actual accuracy of determining the vertical movements of the Earth’s crust (VMEC) based on time series made of four measurement techniques: satellite altimetry (SA), tide gauges (TG), fixed GNSS stations and radar interferometry. A relatively new issue is the use of the persistent scatterer InSAR (PSIn...

Maritime/Marine Spatial Planning (MSP) underpinned by an ecosystem-based approach as one of the core components of integrated marine management is gaining momentum. In turn, a fully-fledged marine cadastre as an integral part of the MSP is still a future vision. The aim of the paper is to explore the Multipurpose, Multidimensional and Interest-Driv...

Simultaneous use of data repeated levelling measurements and continuous GNSS observations allows increasing the spatial resolution of geodynamics models. For this purpose, it is necessary to create a single network, a so-called hybrid network. This paper aims at examining the possibility of using scale-free network theory to determine the most rele...

The simultaneous adaptation of several networks of vertical crustal movements (based on data obtained by various techniques) requires the selection of tie points, which are not affected by additional disturbing factors. These points must be represented in both (or more) networks. They can be the same points or pseudo-nodal points. The selection of...

The crustal movements of the earth can be determined using different data sets. The data sets are characterized by different levels of accuracy, noise, time resolution, and spatial resolution. The goal of the paper is to determine the vertical crustal movements with using the data from satellite altimetry (SA) and tide gauges (TG), permanent GNSS s...
Article
In this paper, seasonal sea level variations have been determined at five locations in the Baltic Sea from satellite altimetry for the period 1993–2015. The results were compared to tide gauge water level data. Annual and semi-annual amplitudes have been investigated for both sea level anomalies and tide gauge water level. It was found that the two...

Vertical crustal movements can be calculated on the basis of Global Navigation Satellite Systems (GNSS) permanent stations positioning results (the absolute motion) as well as on vectors between the stations (the relative motion). The time series, which are created in both cases, include, apart from the information about height, measurement noise,...

In the last years air temperature increasing gradual. It also changes depending on the area: metropolitan, rural. The temperature changes directly affects the expansion of materials of which are made geodetic control network and support infrastructure. This may be influenced on the daily change in the amount determined for permanent GNSS stations....
Conference Paper
Long time span of observations from GNSS permanent stations can be used in the development of models of vertical crustal movements. The absolute vertical crustal movement related to the ellipsoid consists of the observed movement with relation to the mean sea level, the eustatic movement and the geoid uplift. The geoid uplift can be determined from...

To estimate the relationship between vertical movements of the Earth’s crust, geoid temporal changes and Mean Sea Level (MSL) variations, a knowledge about the absolute (determined from satellite and space techniques) height changes over time is required. In this paper, we give an idea of determining the height changes with a use of Vertical Switch...

Long operation periods of GNSS stations give a possibility to use the data in analyzing vertical crustal movements with the accuracy better than ± 0.5 mm/y. During the analysis, the reliability must be considered. This involves the choice of the vertical crustal movements network adjustment method. In most cases, the vertical crustal movements netw...

Models of vertical movements of the Earth’s crust in Poland were developed from levelling data (Kowalczyk, 2006) and GNSS data from the ASG EUPOS network (Kowalczyk, 2015; Kowalczyk et al., 2014; Rapiński and Kowalczyk, 2016). Based on previous studies, an attempt to common adjustment of the relative vertical movement networks created from the leve...

Since the satellite systems have been operative, the data from permanent stations have been used for modelling the changes of the coordinates of the stations. One of the components of the changes is the change of the location of the Earth's crust surface. Both horizontal and vertical changes are analysed, as well as their velocities are determined....

A wide range of interpolation methods are used to build spatial models connected with physical phenomena. Usually, primary data is not placed regularly and the choice of joint is related to the interpolation method used. Through the choice of the interpolation method, we can limit for example the influence of phenomena taking place within greater d...

The development of an elevation frame requires a movement model of the Earth's crust. Currently, regardless of the existence of ASG-EUPOS, it seems that the most reasonable approach is to use the model developed from the levelling data. In Poland three maps of vertical crustal movements were developed on the basis of levelling data. The most recent...

Errors in levelling observations can easily occur. The cause of the errors can be: physical system errors like instrumental errors, observational errors, processing errors like writing or typing errors. It is very important to have a computational test that automatically checks the observations. The “observations” in the adjustment of levelling net...
