چکیده
Multi-dimensional data (i.e., data referenced in one, two, three, and four dimensions) are often managed by transportation agencies with databases and technologies that cannot be integrated due in part to the lack of a comprehensive model for location referencing of the data. This lack of a comprehensive location referencing system data model limits organizations in implementing improved solutions for stakeholders. In this article, a Multi-Dimensional Multi-Modal Transportation Location Referencing System data model is presented that builds on existing data models, allowing multi-dimensional location referencing, multi-scale representation, navigation, feature-level metadata, temporal geographic information system, measurement management, and error propagation. Semantics of data constructs and relationships in the data model are described.
