Event‐oriented approaches to geographic phenomena

Event-oriented approaches to geographic phenomena

This paper is about the information-theoretic foundations upon which useful explanatory and predictive models of dynamic geographic phenomena can be based. It traces the development over the last decade or so of these foundations, from sequences of temporal snapshots, through object life histories, to event chronicles. A crucial ontological distinction is drawn between “things” and “happenings”...

New approaches to neglected phenomena

Modeling Geographic Phenomena as Processes

The common approach to modeling geographic phenomena is based in the objectoriented paradigm. A paradigm that is argued here to be inappropriate and even unable to capture the spatio-temporal essence of the “things” we model. These phenomena include migration, erosion, urban sprawl, percolation, and development, which form the basis of a geographer’s education in processes as opposed to objects...

Approaches to Truth in Geographic Visualization

This paper addresses two related issues: how we can judge and represent 'truth' in the context of Geographic Visualization (GVIS) and what 'truth' is in this context. The first issue is approached from an analytical perspective, with emphasis on measurable aspects of validity in geo-referenced information and on representational methods for depicting validity. In relation to the second issue, a...

Representing Complex Geographic Phenomena in GIS

Conventionally, spatial data models have been designed based on either objector fieldbased conceptualizations of reality. Conceptualization of complex geographic phenomena that have both objectand field-like properties, such as wildfire and precipitation, has not yet been incorporated into GIS data models. To this end, a new conceptual framework is proposed in this research for organizing data ...
