SAC # 74

Geographical Vector Agents and Agricultural Land Use



TIME | 29 October 2009, 4pm onwards

LOCATION | CSAFE Seminar Room, , Dunedin

SPEAKER | Tony Moore


Spatial structures of anthropogenic origin tend to exhibit complex patterns made up of heterogeneous and irregular objects. Complex domains of this kind form a challenge to geosimulation techniques. Geographical Vector Agents (GVA) have been introduced as a vector geometry alternative to raster-based cellular automata (CA); the latter's square cells forming an unrealistic geometric structure for geographic simulation. Given the irregular nature of both domain and technology, an irregular and dynamic GVA has been applied in the Repast agent modelling environment to the modelling of agricultural land use. A simple theoretical scenario will be presented, an attempt to parameterise GVA to model Von Thünen's theory of agricultural land use.

About the Speaker

Tony Moore is a senior lecturer in Geographical Information Science at the School of Surveying, and is the director of the BAppSc course in Geographical Information Systems (GIS). He was previously in the Department of Information Science from 2001 to 2008 and before that working as a coastal / marine GIS Analyst at Plymouth Marine Laboratory in the UK. He completed his PhD (on the application of holistic expert systems to integrated coastal zone management) in 2001. Current research interests include the use of GIS-related technology (e.g. intelligent information systems, grassroots mapping and spatio-temporal modelling) in a decision support context, geographic visualisation and spatial data structures.
