Analysis of geographical concepts for designing a geodata database of railway geodescriptions

The paper considers an approach that allows taking into account both the situational nature of geo concepts and the semantics of geo objects when forming a geodata database of railway geo descriptions. Research in recent years has shown that the best support for a geodata database is provided if concepts are developed in accordance with the specifics of emerging transport situations. To reduce the need to change the geodata schema in geographic information environments, it is necessary to use the structures and functions of situational geographical concepts. The paper presents an approach in which a geoinformation context is linked to concepts, which allows for the extraction of contexts from a geodata database and their interpretation. This helps to uncover the implicit aspects of geodata, add empirical components to geontology, and expand the context of geodata represented in geodata databases. It is assumed that when forming a geodata database of railway geo-descriptions, ontological assumptions about the features of roads can be made, while compatibility problems are solved by formalizing research and practical experience in the open exchange of research results.
