Abstract: The change of geographical elements is closely related to the government administrative examination and approval of construction project. Aimed at the update and application of geographic elements for the government administerative examination and approval of construction project, this paper proposes the idea of integrating the construction and related ontology and the events caused by the change of ontology's state, establishes a spatio-temporal model of construction life-cycle including construction planning, operation, holding and extinction states based on 4D fluent ontology model, and applies in the updating of geographical elements by building objects. The model can record the states of geographic ontology and describe the life cycle continuous and realize association and integration of the geographic ontologies and key events based on time axes of building entities. And it is of great significance for the development of event-based updating of geographic elements, thematic analysis, and city planning and design.
