Purpose. The purpose of the article is to research the peculiarities of creation (updating) of digital topographic maps at the scale of 1:50 000/1:10 000 which would satisfy the requirements for the development of the seamless Topographic Database of the Main State Topographic Map at the scale of 1:50 000. Methodology. The basis for the research is the analysis of the possibilities of applying the theory of databases and knowledge bases, International Standards and specifications and vectorization method. Results. The article examines the peculiarities of creation (updating) digital topographic maps of the scale 1:50000 for the formation of the Main State Topographic Map of Ukraine for the purpose of the creation and maintain the seamless topographic database for national needs, which is located on the Geoportal to ensure the relevance of a single digital topographic basis by topographical monitoring of the territories and for the development of the National Spatial Data Infrastructure in Ukraine. The rules of topological relations between features of the digital topographic maps of the scale 1:50 000 are also defined and given. The peculiarities of providing automated quality control of updated digital topographic maps are investigated. The creation of the seamless Topographic Database of the Main State Topographic Map in the conditions of transfer the cartographic paradigm to geoinformation creates new requirements for the creation (updating) of digital topographic maps of the scale 1:50 000/10 000: creation of spatial schemes, description of the internal design of models and rules of digital description of geospatial features, unification of the features catalog and their attributes, as well as rules of topology between topographic features to ensure topological consistency of geometry in accordance with standards and specifications; creation of the “Validate” software package for checking of created (updated) digital topographic maps at a scale of 1:50 000/10 000 to ensure automated quality control of updated digital topographic maps; creation of new virtual and associated features in the TDB of the Main State Topographic Map. This will increase the intellectual level of geospatial data creation. Scientific novelty and practical significance. The creation of the Main Topographic Map Topographic Database takes into account the use of new virtual and associated features, the use of rules of topological relations between digital topographic map features, providing automated quality control of updated digital topographic maps.
