METHOD FOR HIERARCHICAL SCHEMA REPRESENTATION FOR 3-DIMENSIONAL INFORMATION MODEL OF ROAD

摘要

Disclosed is a method for representing a hierarchical schema for a three-dimensional information model for a road. According to one embodiment of the present invention, provided is a data structure in which a schema for defining a standard information model for a road is represented. The schema a) is defined in an express language; b) follows a hierarchical structure regulated in IFC4 or ISO 16739; c) includes a plurality of shape entities representing the shapes of elements configuring the road and a plurality of type entities representing the type of each shape entity, wherein the each type entity has an enumeration data type for enumerating a plurality of detailed types; and d) allows the shape entities and the type entities to be ranked lower than a plurality of conceptual entities configuring a hierarchical structure.
