The purpose of this paper is to present all the steps taken to prepare the digital topographic map of the lands in Constanta and Tomis harbors. This had as its objectives two major stages: the recognition of the existing national geodesic network in the field and the determination of the geodetic support network, and the second stage consisted in linking the altimetry network to the national altimetry system. Recognition of points in the national geodetic network from the A/B national GNSS network and identifying the permanent GNSS stations in the area has been performed. Measurements to determine plan metric coordinates have been divided into several stages: the first stage was determined by the static GNSS measurements in the geodetic support network, in the second stage they were determined by the classical measurements using the Leica TCR805 Total Station, and the connection to the Stero70 coordinate system was made by the points of the geodetic network determined in the first stage by Static processing. In the third stage, static GNSS measurements in the geodetic grid are determinant, points located in isolated areas and having a distance of between 200 and 750 m.
