“…This bidirectional relationship between data and concepts contrasts with other unidirectional, top-down, geospatial approaches that introduce spatial and/or temporal constructs at the epistemological or ontologic levels (Benslimane, et al, 2000;Camara, 1994;DeOliveira, 1997;Fonseca et al, 2000;Hadzilacos & Tryfona, 1996;Kosters, et al, 1997;Pullar & Stock, 1999;Renolen, 2000;Shekar, et al, 1997;Smith et al, 1991). It also contrasts with non-geographical meta-representations in which the link between data and concepts is mainly unidirectional, either top-down (e.g.…”

Abstract. In many geoscientific disciplines concepts are regularly discovered and modified, but the architecture of our geospatial information systems is primarily aimed at supporting static conceptual structures. This results in a semantic gap between our evolving understanding of these concepts and how they are represented in our systems. The research reported here provides better database support for geographical concepts that evolve with particular situations. To reduce the potential for schema change in such environments, we develop an analysis of the structure and function of situated geographical concepts and directly model the results in an UML schema. The developed schema explicitly contextualizes geographic information and concepts, enabling the extraction of contexts and interpretations from databases. This aids (1) the addition of empirical components to a geoscientific ontology, (2) the representation of context in geo-databases, and (3) the uncovering of the implicit aspects of data, and the sharing of meaning, via the represented contexts. Prototype implementations that show promise for managing geoscientific ontologies and databases are also briefly discussed.

“…Current GIS design is based on a 2D and static representation of geographic phenomena and must be extended to handle both space and time. Spatio-temporal GIS research has been a lively topic since the late 1980s (Renolen 2000). Several key approaches have been proposed to represent space and time in GIS, including the snapshot model (Armstrong 1988), the space-time composite model (Langran andChrisman 1988, Langran 1992), the object-oriented approach (Worboys 1992(Worboys , 1994, the event-based approach (Peuquet and Duan 1995), and the three-domain model (Yuan 1996).…”

Today, the opportunity for potential human activity has gone beyond physical space to virtual space. Based on a proposed conceptual framework that models the relationships between physical and virtual spaces, this paper presents an attempt to adjust the space-time prism concept of Hä gerstrand's time geography to identify potential activity opportunities in virtual space, focusing on the virtual space access channels available in physical space. A three-dimensional (3D) spatio-temporal Geographic Information System (GIS) design has been developed in this research to accommodate the adjusted space-time prism concept to support the representation, visualization, and analysis of potential human activities and interactions in physical and virtual spaces using the prism representation. Following the design, a prototype system has been successfully implemented in a 3D GIS environment. Such a system can provide powerful analytical tools for studies related to potential human activities and applications such as locationbased services (LBS) and accessibility analysis in the information age.

“…existence, non-existence, and transition) has been provided by Hornsby and Egenhofer (2000), which actually models each entity with its own life-cycle. Similarly, Renolen (2000) introduced a behavior modeling framework where each spatiotemporal object experiences its generic behavior as either alive or dead, and seven types of transition between two status: creation, alteration, destruction, reincarnation, annexation, deduction, and reallocation. Several studies applied this framework in specific applications (Bothwell and Yuan, 2011;Guilbert and Lin, 2007;Nixon and Hornsby, 2010) where objects can merge or split leading to the creation and destruction of new objects.…”

The urban heat island phenomenon occurring within urban areas or city-clusters is increasingly becoming a severe problem in the urbanization process. Previous research mainly focusing on static urban heat island modeled at fixed time instants is not capable to track the evolutionary process of the urban heat islands in both time and space domains. This research designs an object-oriented dynamic model to reconstruct the evolutionary process of urban heat islands. Each urban heat island is modeled as a spatiotemporal field-object with it own life-cycle. The dynamic behavior of an urban heat island is defined by a series of filiations (e.g. expansion and contraction). The model was implemented in an object-relational database and applied to air temperature data collected from weather stations in hourly-basis over seven days. The behaviors of UHI were extracted from the data. Results suggest that the model can effectively identify different behaviors and status of urban heat islands, and reveal the spatiotemporal behavior of each of them.
