2 1. Introduction National Agency for Cadastre and Land Registration Profile: state organization dedicated mainly to the realization of the new cadastre system in Romania together with the land registration ; self financing institution of the Ministry of Administration and Internal Affairs; organized in the central divisions, local county offices for C&LR (42) and National Centre for Geodesy, Cartography, Photogrammetry and Remote Sensing (NCGCPRS); represents also the NMA (National Mapping Agency) including central divisions Geodesy and Cartography, National Geodetic Fund, and NCGCPRS; Products and services for C&LR but also as NMA: - Realization and maintenance of geodetic networks in Romania: classical and satellite technologies; - Cartographic products at different scales (1:100000, 1:50000, 1:10000, 1:5000 etc.) in analog and digital format (raster, vector); ERM, EBM, Euro DEM et al. - Orthophoto maps based on photogrammetry and remote sensing > 2006 all Romania covered at 1:5000 scale; This year will start products at 1:1000 and 1:500 scale for main cities; - Cadastral maps et al. National Geodetic Network: classical terrestrial network; satellite based network EUREF Symposium, Brussels, June 18-21,

14 5. (Quasi)geoid in Romania Gravity data availability (Tomoiaga T., 2007) EUREF Symposium, Brussels, June 18-21,

15 5. (Quasi)geoid in Romania EUVN97 4 stations in Romania EUVN_DA 43 GPS/leveling stations in Romania EUREF Symposium, Brussels, June 18-21,

16 5. (Quasi)geoid in Romania H. Denker, April, 21-22, 2008, Bucharest, (Regional workshop on Geodetic Data Exchange) EUREF Symposium, Brussels, June 18-21,

17 5. (Quasi)geoid in Romania Regional Distortions of the EGG97 (Case study for Romania) Tenzer R, The Prutkin 4 th I, degree Klees Rcorrector surface. DEOS, TU Delft, Kluyverweg 1, 2629 HS Delft, The Netherlands Rus T, Avramiuc N NACLR, Splaiul Independentei 202A, , Bucharest, Romania The height anomaly residuals after applying the 4th degree corrector surface (min = cm, max = 12.3 cm, mean = -0.1 cm, RMS = 4.2 cm). The innovation function approach was applied to combine the gravity and GPS/leveling data in Romania. The combination shows a presence of regional distortions of the EGG97 at the border of the country. The reason may be due to inconsistencies with data sets from Bulgaria, Moldova and Ukraine. The regional trend of these distortions was estimated to be between -36 cm and 24 cm with uncertainty of about ±4 cm, providing that the height reference surface can be defined with the sub-decimetre accuracy. Since the low spatial density of the GPS/levelling points and their irregular distribution especially at the areas where large distortions were documented, further investigation should be conducted using a better quality of GPS/levelling data sets.

18 6. National-European CRS connection Need for transformation from National CRS <> European CRS (ETRS89): TransDat Software and model (2D) realized on a common set of points (~ 500): not yet implemented / availability of necessary common points by end of 2008 ETRS89 TransDat Stereographic 1970 EUREF Symposium, Brussels, June 18-21,

19 7. Conclusions CONCLUSIONS ANCPI unified cadaster/land registration/mapping agency in Romania Geodetic Networks: triangulation/leveling not so well maintained / reconstruction infrastructure projects / new inventory / leveling on GNSS net Romanian GNSS Network (Class A-perm. stations, B-epoch stations) integrated in the IGS and EUREF-EPN by 5 permanent stations ROMPOS (2008) realized according to EUPOS standards; Need for (quasi)geoid in Romania based on different approaches (gravity + GPS/leveling); National-European CRS connection: software realized / data not ready EUREF Symposium, Brussels, June 18-21,
