Analysis of the sides lenght of 3rd class horizontal geodetic networks on the basis of data from 56 counties

This paper presents selected geometric characteristics of 3rd class horizon-tal geodetic networks, calculated on the basis of data from 56 counties, and its statistical analysis in relation to the G-1Technical Instructions. The authors also uses the correlation analysis and method of graphs as a tool to determine the degree of linkage between each features. Derived parameters of the average object can be used to create regular models for testing various geodetic aspects ...

Effects of replacing the classical 3rd class horizontal geodetic network reference points by vectors to ASG-EUPOS system stations

This paper shows contents of analyses regarding the adjustment of the classic 3rd class horizontal geodetic network integrated with GNSS measurements in the ASG-EUPOS system. The tests were carried out on two regular theoretical models with similar parameters of reference points density and the network side length, but with different geometric structures in terms of shape and travers length. ...
