Realization of EUVN densification project in the Republic of Croatia

Croatia has successfully joined EUVN project by establishing 8 EUVN points in 1997. The project of densification of EUVN (EUVN_DA) started in Croatia in 2005. Detail preparations, new site definitions, field works and processing brought 12 new sites. The field works included GPS, gravimetric and precise levelling measurements. Total number of EUVN sites has expanded from 8 to 20. Besides the densification with new EUVN_DA points, due to some indications about their quality, some control measurements were carried out also on the old EUVN points. In four of them the problems were located and solved. The quality of EUVN and EUVN_DA points is checqued using European EGG97 and Croatian national HRG2000 geoids. With the new data Croatia successfully continue to contribute to EUVN projects.
