About the use of the coordinate transfer from the local system to the official coordinate system and vice versa (Bulqiza mine as a case study)

Abstract
The chrome mine in Bulqiza has been exploited since 1948. The exploitation of the mine required the creation of a graphic documentation in which all the constructions of the mine are visualized. The visualization is created in three planes (horizontal, vertical, and in profile) and initially referred to a local coordinate system. Although the Bulqiza mine was connected to the official coordinate system (Gauss-Kryger system at that time) in 1972, the application of the system continued due to the large amount of work required to convert from the local coordinate system to the official system (GK). This year (January 2022), due to the concession of the mine to a foreign company, the creation of a calculation model for the transformation of coordinates from the local to the official coordinate system was required. Since the official geodata portal ASIG (State Authority for Geospatial Information) provides the possibility to obtain coordinates in the three official coordinate systems used in our country (Gauss Kryger, UTM and KRGJSH), we deal with the creation and evaluation of the following model of transformation from local system to GK. Moreover, the georeferencing of images is produced in order to obtain, through digitization, geodata that allow to recreate all the graphic documentation in the official coordinate system.
Key words: Chrome mine Bulqiza, graphic documentation, coordinate system, local coordinate system, official coordinate system, computational model, geo-referencing of images.
