The first of this year's QMRG-sponsored Spatio-temporal Modelling in GIS
Environments eSeminars!
Wednesday 18th October
Representations of space and time
Donna Peuquet
Department of Geography
The Pennsylvania State University
Chair/Discussant: Derek Karssenberg
Donna Peuquet is Professor of Geography at The Pennsylvania State
University. Her current research interests include theory of geographic
knowledge representation, spatio-temporal data models, spatial cognition,
spatial analysis methodologies, geographic database design, and the use of
GIS in epidemiological research. Her book, ‘ Representations of Space and
Time’ develops an integrated perspective on philosophical, cognitive and
technical issues on spatial and space-time representation.
Synopsis:
Major geographic information systems (GIS) software products, such as
ESRI’s Tracking Analyst, can track point objects through space. In spite
of their effectiveness for specific tasks, these systems are not able to
represent the full potential complexities of space-time data needed for
sophisticated space-time analysis. This presentation will examine the
conceptual issues involved in representing space-time information, and why
this remains an active area of GIScience research since space-time
representation in GIS first gained attention over fifteen years ago.
Beyond the conceptual, and even downright philosophical issues involved,
some space-time representation approaches will be presented for GIS that
have been discussed and debated in the literature. Within this context,
one example will be described of an increasingly accepted, multi-
representational approach, which integrates location-based and object-
based as well as time-based views. In conclusion, the potential of GIS
with true space-time representation and analysis capabilities will be
considered.
