National Geodetic Points are part of the national geodetic networks and provide a reference frame i.e. geodetic datum. National geodetic Points, connected in the networks, together with geodetic measurement and, measurements processing mechanisms for the determination of their coordinates and their connection to the European reference system are all fundamental elements of a new coordinate reference system in the Republic of Slovenia. A national geodetic point is established when it is materialized (means physically established with a permanent designation) and when its coordinates are defined in a National coordinate reference system. Their coordinates must be determined with a high precision, accuracy and reliability. National Geodetic Points are a physical presentation of the Slovenian national coordinate reference system and provides a linkage to the European coordinate reference system - ESRS. They serve as reference points for the determination of position changes in time and determination of transformation models or parameters between old and new national coordinate reference system.
