Abstract
The process of digitalization of the state, including the development of the national spatial data infrastructure, promotes new requirements for the creation of intelligent core reference data based on international and harmonized national standards and specifications. The main result is digital topographic maps in topographic-geodetic and cartographic production in the cartographic paradigm, that do not take into account the use of new associated features, the rules of the digital description of topographic features, and the rules of topological relationships between map features. Digital topographic maps have a unified content following the Classifier of the information displayed on topographic maps of scales 1:10 000 – 1:1 000 000. This Classifier was developed according to the rule: a feature has its own symbol and topographic code. Geoinformation technologies allow creating of complex features. Therefore, the goal of the research is to formulate the rules for creating complex (associated) geospatial features to ensure the intellectual level of topographic databases, which are the main product of the geoinformation paradigm. The article presents the concept of a complex (associated) feature based on the national standard DSTU ISO 19107:2017 Geographic information. Spatial schema (ISO 19107:2003, IDT). There are four types of collections of terrain objects that are considered in detail: geometric aggregates, geometric complexes, geometric composites, and global geometric complexes. Examples of features displayed on digital topographic maps were given for these types. The established rules for creating associated geospatial features must be taken into account during the development of the specifications of geoinformation products to ensure further compatibility and integration of core reference and thematic geospatial data in the NSDI.
