    Spatial hierarchical reasoning applied to administrative boundary design using GIS
    Eagleson, S. ; Escobar, F. ; Williamson, I. P. ( 1999)
    Throughout history, humankind has segmented and structured the spatial 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 identify issues associated with the division of our geospatial environment. Also, to investigate new methods for the organisation of 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 its use in reasoning. The study aims to examine the global extent of the problem, while focusing on solutions for the state of Victoria, Australia.

    Automating the administration boundary design process using Hierarchical Spatial Reasoning theory and Geographic Information Systems
    Escobar, F. J. ; Eagleson, S. ; Williamson, I. P. ( 2000)
    Throughout history, humankind has segmented and delineated the geographic 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 Geographic Information System (GIS) 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 present the findings of a research project aimed 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. In the first section, the paper outlines the problem of data exchange and data integration encountered world-wide when utilising current administrative boundaries and the data attached to them. It also reviews the most commonly adopted methods to overcome the problem and the issues inherent to these methods. Secondly, the paper introduces the concept and theory of HSR and reviews common practices in boundary design. The paper summarises constraints and issues arising from the use of GIS jointly with HSR in polygon-base design. Thirdly, an HSR-based prototype developed for delineating boundaries within the GIS environment is detailed. This prototype has been constructed utilising the state of Victoria, Australia as a working laboratory for development and analysis. The prototype has been implemented in ArcView (ESRI) using cadastre (land parcels), road network and major natural barriers as the core information and Avenue as the programming language. In the prototype, the agencies considered were ABS (Australian Bureau of Statistics) and Australia Post due to their widely acceptance and use amongst institutions and individuals dealing with geospatial data and analyses.

    North West Melbourne data integration project
    EAGLESON, SERRYN ( 2012)
    This publication highlights the importance of a national land administration infrastructure to support sustainable development. It contains a summary of research connected to the national infrastructure for managing land information project funded by the Australian Research Council Grant (LP0990571:2009-2012). This summary also covers other related research conducted overthese last four years. The projects identifies the drivers and components required for better management of land and property at a national level for Australia and makes recommendations for similar federated countries. The research project has been coordinated through the Centre for Spatial Data Infrastructures and Land Administration, the University of Melbourne in close collaboration with industry partners.
