The International Height Reference System (IHRS) was defined by the International Association of Geodesy in 2015. Since then, the international geodetic community has been working on the specification and establishment of its realisation, the Interna

Islands and the mainland are separated by seas, and the distances between them might be so long that the height on the mainland cannot be exactly translated to the islands, resulting in different height systems on the mainland and the islands. In thi

The International Association of Geodesy (IAG) aims to establish the International Height Reference System (IHRS) as one of its primary scientific objectives. Central to the realization of the IHRS is global vertical datum unification, which requires

A unified height datum is essential for global geographic information resource construction, ecological environment protection, and scientific research. The goal of this paper is to derive the geopotential value for the Chinese height datum (CNHD) in

The high-precision unification of global height datum has long been a hot issue in the field of geodesy. The chronometric leveling method originates from the gravitational redshift effect of general relativity, which may provide a new solution for th

In December 2018, a new national height system called the ‘Slovenian Height System 2010’ was introduced (denoted as ‘SVS2010’). It is based on a new levelling network of the first order, which has been measured over the previous decade. For g

In this article, an overview of the height geodetic data of Slovenia that were determined on a basis of observations from various tide gauges along the Adriatic coast is presented. This is followed by the definition of the Koper height geodetic datum
