Classic representation of the terrain through contour lines derived from DTM remains the best method of surfacing the earth on a map, nevertheless the correlation with other layers such Hidrography are mandatory. In the context of the current national coverage of the Digital Terrain Model, one of the main concerns of the National Center of Cartography, through the Cartography and Photogrammetry department, is represented by the exploitation of the available data in order to update the layers of the Topographic Reference Map 1:5000, known under the name of TOPRO5 and, at the same time the 1:50 000 scale map of Romania. This paper investigates the perspective of using DTM derived products along with other data sources in the process of updating the layers of TOPRO5. Other future perspective for creating a 3D version of the base layers of TOPRO5 are presented
