Current trends and future perspectives of the Lithuanian national geodetic vertical network

Abstract

The article discusses the condition of the Lithuanian National Geodetic Vertical Network. It reviews the history of the vertical network’s establishment and contemporary needs. The article examines the technical regulation GKTR 2.12.01:2001, which outlines the requirements to ensure network quality. The analysis uses data from the first geodetic network’s establishment between 1998 and 2008 and data from the 2023 renewal of the vertical network’s 5th polygon to assess and determine the condition of existing geodetic marks. The study showed that the installation of geodetic marks is becoming increasingly challenging. Also, the research revealed that the number of destroyed geodetic marks has decreased. More attention should be given to the technical protection of geodetic marks and updating legal regulations to ensure the longevity of geodetic networks.
