“…The second one generates a new object instance with a unique identifier as soon as an object has changed (Lohfink et al. ) (see Figure , middle row). The identity determines the existence or non‐existence of an object and can undergo a set of possible changes, formally described by Hornsby and Egenhofer ().…”

In information systems, ontologies promise advantages such as enhanced interoperability, knowledge sharing, and integration of data sources. In this article, we show that the upper ontology Basic Formal Ontology can facilitate the modeling of an evolution of administrative units. This is demonstrated by creating a spatiotemporal ontology for the administrative units of Switzerland. The ontology tackles the problem that the geometric data is typically captured by taking snapshots at regular intervals while the thematic data is continually updated. The ontology presented merges time‐stamped geometries with a formally described history of administrative units, allowing for complex spatiotemporal queries neither standard approach would support. The resulting populated knowledge base was evaluated against a set of spatiotemporal test queries. The evaluation showed that this knowledge base supports a wide range of queries on the evolution of the administrative units of Switzerland between 1960 and 2010.

“…Both models have inherently negative aspects, such as data redundancy and representation problems (Yuan, 1996a). Subsequent progress has been made to propose event-based (Peuquet and Duan, 1995;Worboys, 2005) and object-oriented data models (Worboys, 1992;Wachowicz and Healey, 1994;Rapper and Livingstone, 1995;Lohfink et al, 2007). Event-based models focus on changes rather than spatial objects per se.…”

This paper introduces a comprehensive approach to support dynamic, large-scale spatio-temporal vector database development. The approach is based on a version-difference spatio-temporal data model that targets common problems in developing large-scale spatio-temporal vector databases. The scenario is to establish a National Fundamental Geospatial Information Dynamic Database (NFGIDD) in China. The proposed methodology was demonstrated by an experimental spatiotemporal database system that consists of a database management platform and a data processing system. The experimental results show that our methods have significant advantages over traditional spatio-temporal data models.

Creating and Validating Object-Oriented Geographic Data Models: Modeling Flow within GIS

Object‐oriented geographic data models provide an organizational scheme to associate domain specific meaning to primitive GIS elements like points, polylines, and polygons. Although use of data models is widespread in the GIS community, the design process is not necessarily obvious and often ad hoc. This article outlines a procedure for the creation and validation of geographic data models through the examination and distillation of use cases. As an example, the article follows the development of a data model for the spatial concept of flow. Flow, the collective movements of people, materials, or ideas, is a common driver of geographic change, not generally supported by functionality within contemporary GIS, and an abstract dynamic entity that would presumably be difficult to model. Model design was facilitated through the distillation of flow cases of tabular human migration data, Minard's map of Napoleon's march on Moscow, and stream channel routes in a karst watershed. Unified Modeling Language diagrams are created for each case and the models' commonalities combined to yield a generic data model. As a means of validation, each use case was instantiated with the generic model and tested to re‐create the fundamental components of flow and address predefined typical queries.
