“…The focus of data models in GIS has been on spatial, at the expense of temporal, dimensions (Peuquet 2002). Space and time can be defined in absolute or relative terms (Blaut 1961;Couclelis 1997;Wachowicz 1999;Goodchild 2002). Whereas absolute space and time offer a rigid geometric structure within which phenomena are referenced, the relative view references location largely in terms of relationships, topological and temporal, between features (Peuquet 2002).…”

Abstract. The use of object-orientation for both spatial data and spatial process models facilitates their integration, which can allow exploration and explanation of spatial-temporal phenomena. In order to better understand how tight coupling might proceed and to evaluate the possible functional and efficiency gains from such a tight coupling, we identify four key relationships affecting how geographic data (fields and objects) and agent-based process models can interact: identity, causal, temporal and topological. We discuss approaches to implementing tight integration, focusing on a middleware approach that links existing GIS and ABM development platforms, and illustrate the need and approaches with example agent-based models.Key words: Object-orientation, Agent-based models, Spatial-temporal modeling, Topology IntroductionThis paper addresses the representation of both form and process, as spatial data models and spatial process models, respectively, and how relationships between these representations might be structured to better facilitate scientific inquiry and application.

“…Dimension / Task / Function: terms here characterize the data for the task at hand, and are often defined according to some dimension or general function (time, space) rather than a semantic quality. The field / object distinction in GIS circles seems to work at this level (Cova & Goodchild, 2002). 4.…”

Practical implications include suggestions that current generalist approaches to systems design may be too removed from the specifics of the task at hand, and that information professionals in their education and training need to be exposed to a wide range of perspectives, reflecting the various human contexts in which their technical expertise is likely to be deployed. What is desirable is a sophisticated appreciation of the many contexts in which ICTs function.

“…Cova and Goodchild [22] have addressed the digital representation of A(x) when it is unique to x. They define an object-field as a mapping of location x to area A(x), and identify several other applications.…”

“…A workshop in 1988 brought together the small community of researchers working on the problem, and led to a first book [1]. Two international biennial conference series were established in the 1990s (the 6 th International Symposium on Spatial Data Quality meets at Memorial University, Canada, July 6-8 2009; and the 9 th International Symposium on Spatial Accuracy Assessment in Natural Resources and Environmental Sciences meets at the University of Leicester, UK, July [20][21][22][23]2010).…”

Abstract. The location of an event or feature on the Earth's surface can be used to discover information about the location's surrroundings, and to gain insights into the conditions and processes that may affect or even cause the presence of the event or feature. Such reasoning lies at the heart of critical spatial thinking, and is increasingly implemented in tools such as geographic information systems and online Web mashups. But the quality of contextual information relies on accurate positions and descriptions. Over the past two decades substantial progress has been made on the theory and methods of geospatial uncertainty, but hard problems remain in several areas, including uncertainty visualization and propagation. Web 2.0 mechanisms are fostering the rapid growth of user-generated geospatial content, but raising issues of associated quality.
