Results of the state geological mapping at a scale of 1 : 1,000,000 (third generation) of the Russian Federation and its continental shelf

Abstract. The paper presents 30-year results of small-scale mapping in Russia (1995–2025). There is a historical background for preparing the State Geological Map of the Russian Federation territory and its continental shelf at a scale of 1,000,000 (third generation); there are main stages of creating regulatory and procedural documents to compile and edit sheets of the specified geological map; the authors assess the issues requiring prompt solutions: organizational, financial, and methodological support, improving the map quality and predictive efficiency. The paper informs about the key results of implementing the Program to create the State Geological Map at a scale of 1,000,000 (third generation) as the major stage of exploring and improving the level of small-scale coverage of the country’s territory and its continental shelf, as well as developing digital mapping. The national geological and cartographic resource “Digital Twin of Russian Subsoil” contains a sheeted digital data set (248 topographic sheets) and allows planning medium-scale and large-scale geological survey and exploration work, updating integrated and review geological maps, and implementing the next stage of monitoring the specified geological map, which involves updating regularly maps within the single geological and cartographic model of the Russian territory and its continental shelf.
