Three cross-border levelling lines between state levelling networks of Republic of Bulgaria and Republic of North Macedonia are made. The purpose of the realization of these lines is connecting of the state levelling network of Republic of North Macedonia in European Vertical Reference System. That could be made directly through the Bulgarian state levelling network ? part of UELN95/98 from 2003. Precise levelling measurements are initialized from the state geodetic agencies - Agency for Real Estate Cadastre of the Republic of North Macedonia (Former Yugoslav Republic of Macedonia - FYROM) and Agency for Geodesy Cartography and Cadastre of the Republic of Bulgaria.
Implemented cross-border levelling lines connect first order levelling lines of the two state levelling networks. As a result are formed two closed levelling polygons. Estimation of connection of the both height systems is made from calculated misclosures. The result of estimation of the realized connection between state levelling networks is valid for the cross border region. The same estimation of connection is made with the height and geopotential data of fundamental nodal benchmarks in the two countries. The achieved results could be successfully used for realization of state levelling network of Macedonia in EVRS. |
