Realization of the vertical datum and height system of Lithuania

Abstract

The vertical datum and height system adoption is crucial in development of national geodetic reference. The gravity and height systems should be related with the geocentric geodetic coordinate system. In Lithuania such a system was adopted in 1994 as a Lithuanian Coordinate System (LKS 94). It consist with European Terrestrial Reference System 1989. Since 1998 the main Lithuanian geodetic activities were related to the development of the Lithuanian National Geodetic Vertical Network. The network should implement unified system of heights in the territory of Lithuania and guaranty reliable connection with other European height systems. Lithuania is participating in the United European Levelling Network and European Vertical Network project, and is planning to adopt the common European Vertical System.
