The creation of digital 3D geological models has become relatively common in recent years with the development of computer technology, the deployment of powerful algorithms and the intense work of larger teams. Also at the State Geological Institute of Dionýz Štúr, several geological tasks were carried out in this area: "Upper Nitra Basin - Three-Dimensional Geological Modelling of the Exposed Area" (Kotuľová et al., 2010), as well as the multilateral International Project "TRANSENERGY" (Černák et al., 2012), "Turčianska kotlina Basin - Three-Dimensional Geological Modelling" (Nagy et al., 2014) and in the years 2016-2019 the task "3D Geological Model of the Slovak Republic at Scale of 1: 500,000" (Zlocha et al., 2019). SGIDŠ's progressive approach to this issue in the last decade has been reflected not only in the use of explicit and implicit approaches to modelling, similarly to the world, but also in the development and application of its own methodological procedures and algorithms, implemented by its own applications. The 3D geological model of the Slovak Republic at the scale of 1: 500,000 is one of the first national models at all. From commercial softwares, the following were used in its creation: Petrel ® 8.4 and ISATIS™, for import / export of data, for creation of virtual boreholes, profiles and sections own applications and for visualization of results ArcScene™ of ESRI® company and own web application on ArcGIS™ Enterprise 10.7.1 platform with API for JavaScript. In the article we briefly describe the process of creating a 3D geological model, source data and the methodology of their processing, the methodological procedure of the solution and the main results of 3D modelling with a number of attached images are provided.
