Unified geological-cartographic model of the Russian Federation and its continental shelf

Abstract. The paper outlines the first stage results of developing the Unified geological-cartographic model to technologically support State Geological Map (scale 1 : 1,000,000) monitoring of the Russian Federation territory and its continental shelf. The model integrates cartographic documents, serial legends, and explanatory notes, which contribute to the seamless coverage of the country’s territory. The multi-level data design, interserial correlation, and geological description formalization with hierarchical directory determine the Unified geological-cartographic model development. The technology includes structured arrays of digital geological information databases, plug-ins to download, analyze, and display them. Integration of digital geological resources and computer-assisted map monitoring in a unified user interface is outstanding. The data model allows forming multiscale-level geological maps and supports data succession, excluding conflicts and duplications. The project contributes to standardizing and updating geological information, with international standards and technological sovereignty considered. It is projected to develop the system for multiscale analysis, outlining prospective subsoil areas, computer-assisted map generalization. Domestically and globally, the novel industrial technology to monitor State Geological Map sets therefore corresponds to the nation-wide Unified geological-cartographic model. The model currently has 19 uploaded State Geological Map sets (scale 1 : 1,000,000, third generation) to monitor, which include 16 map types and diagrams, over 3.5 bn geological objects, and 110,000 mineral resource objects. The vast operating experience and new tasks upon monitoring facilitate further technology development.
