Approaches to the integration of the application conceptual schemas in the unified geoontology

An approach is presented to ensure the coordination of heterogeneous applied conceptual schemes that describe individual subject areas with sufficient completeness, based on their unification and integration in the form of a universal, unified geoontology. Possible factors of heterogeneity of particular conceptual schemes are considered, requirements and main design solutions for building an unified geoontology intended for use in the context of a multiaspect geodatabase are presented. The data structure for building such an unified geoontology is shown.
