New official geodetic datum of Croatia and CROPOS system as its implementation
Bosiljevac, Marinke and Marijan Marjanovic
On the basis of the Law on State Survey and Real Estate Cadastre, the Government of the Republic of Croatia, made at its meeting on August the 4th 2004 the Decree on establishing new official geodetic datum (horizontal and vertical), gravimetric datum and map projections of the Republic of Croatia. New official geodetic datum and plane map projections will be implemented into the official use gradually until January the 1st 2010 at the latest. The State Geodetic Administration is entrusted with the task of developing a program for implementing new official geodetic datum and map projections into the official use. Within PHARE Project on Modernization & capacity building of integrated land administration system in Croatia a national reference network CROPOS CROatian POsitioning System will be established. The purpose of the project is to build a system of reference stations of the Republic of Croatia that would diminish the expenses and accelerate the processes of state survey and real estate cadastre jobs, and enable an efficient introduction of the new geodetic datum and map projections. Implementation of a national GNSS network comprised of 30 reference stations covering the whole territory of Croatia and control centre, which will allow to pass from the current approximation of 2.5 m to a level of precision of 0.02 m for each positioning in real time. The tender for the CROPOS will be launched in August 2006. In this paper the overview of activities concerning definition and implementation of new geodetic datum and preliminary works for establishment of CROPOS system will be presented.
