Hierarchical spatial reasoning applied to the automated design of administrative boundaries using GIS

Abstract

Throughout history, humankind has segmented and delineated the geospatial environment in various ways to support administrative, political and economic activities. To date, the majority of spatial boundaries have been constructed in an uncoordinated manner with individual organisations generating individual boundaries to meet individual needs. This practice has resulted in boundary layers that even the most sophisticated GIS (Geographic Information System) technology is unable to cross analyse accurately. Consequently, geospatial information is fragmented over a series of boundary units.

The objective of this paper is to investigate new methods for the organisation of spatial data by applying the principles of Hierarchical Spatial Reasoning (HSR), where HSR can be used as the theoretical framework for investigating the hierarchical structuring of space and for providing new methods for accurate data exchange. Also, to present the issues found in the development of a prototype developed for delineating boundaries within the GIS environment. This prototype has been constructed utilising the state of Victoria, Australia as a working laboratory for development and analysis.
