By applying modern technology, it is felt to increase the speed of execution of complex topographic works/projects, such as the connections between adjacent mining perimeters, but different as a topographical reference system. Due to these types of works there are problems of extending the topographical network within the mine field and beyond its limits. It should be borne in mind that the topographic network was constituted at that time in the applied reference system, either locally or localized to the national one. Regarding these aspects, the need to find ways of homogenization between the different reference systems applied in the territory of our country appeared. In this study, we discuss the coordinate transformation module from a local reference system in the national systems, Gauss Kruger and STEREOGRAFIC 70, for the Anina mining field. For the Anina mining field, the name of the reference system was given by the Ministry of Mines with the name of the plain mine and the year of construction, namely ANINA 17. The ANINA 17 reference system was materialized through a complex topographic triangulation network. Adopting the initial coordinate system is a step forward in the direction of sorting topographic projects. With the expansion of these works in adjacent areas, attention was drawn to the difficulties encountered in the calculations and graphical interpretations in the four quadrants of the coordinate system. Finally, the existing mining system is adopted by changing the values for the origin point S from the initial coordinates YS = 0.000 and XS = 0.000, then YS = 5.000,000 and XS = 5.000,000, so that in the end the coordinates of the origin S are YS = 50.000,000 and XS = 50.000,000 , Y remains pointing to north, and Z is set against the middle level of the Adriatic Sea. This new Reference System was called the Popului Projection. The link between the Popului Projection and the national reference system was achieved by transformation the coordinates of this project into the Gauss 1962 projection through the analytical method based on common point pairs.
