“…A great number of papers, studies and reports deal with this problem (e.g. Collier et al, 1998;Cai, 2000). The rapid development of GNSS technology has brought an extra requirement for the connection of the classical local geodetic datums with the more modern global Terrestrial Reference Frames (TRFs).…”

Abstract:In the present paper we are dealing with the problem of the connection of two local geodetic datums in which the classical transformation procedures fail to give sufficient solution. Thereafter, we additionally implemented Least Squares Collocation in order to model the remaining residuals of the initial transformation. We tested this methodology in an area located in Northern Greece and we found significant improvement of the transformation results. The implementation of Least Squares Collocation refines the statistical behaviour of the inconsistencies regarding their extreme values (minimum and maximum) from almost 70 to 23 cm, while the standard deviation is reduced from the level of 27 to 10 cm.

“…Thereafter, some additional mathematical tools were developed to model the remaining transformation residuals such as: Least Squares Collocation (LSC, e.g. Collier et al, 1998;You and Hwang, 2006;Li et al, 2012), Finite Elements Model (FEM, e.g. Kohli and Jenni, 2008) or other models (e.g.…”
