  • Cadastral “reform”—at what cost to developing countries? 

    Ezigbalike, I. Chukwudozie; Benwell, George L
    This paper argues that the introduction of western cadastral concepts into communities with different land tenure systems have involved “cultural costs.” The paper discusses these cultural costs and concludes that cadastral ...
  • Development of a generic system for modelling spatial processes 

    Marr, Andrew; Pascoe, Richard; Benwell, George L; Mann, Samuel
    In this paper is proposed a structure for the development of a generic graphical system for modelling spatial processes (SMSP). This system seeks to integrate the spatial data handling operations of a GIS with specialist ...
  • GIS maturity and integration 

    Marr, Andrew; Benwell, George L
    This paper discusses the concept of maturity in the use of GIS and then formulates a computational method for measuring an organisations maturity level from the construction of a surrogate indicator. Generation of this ...
  • GIS, expert systems and interoperability 

    Lilburne, Linda; Benwell, George L; Buick, Roz
    How should geographic information systems be developed? There is a strong demand from users for enhanced functionality and power. Vendors can and do respond to these demands. But where will this lead? Will the result be ...
  • Landscape structure and ecosystem conservation: an assessment using remote sensing 

    Mann, Samuel; Benwell, George L; Lee, William G
    Analyses of landscape structure are used to test the hypothesis that remotely sensed images can be used as indicators of ecosystem conservation status. Vegetation types based on a classified SPOT satellite image were used ...
  • Local government GIS in New Zealand since 1989 

    Marr, Andrew; Benwell, George L
    This paper draws together existing data with recent survey results and compares the development of local government GIS with the evolution of Information Systems (IS). These comparisons are made using the philosophy that ...
  • Measuring spatial accessibility to primary health care 

    Bagheri, Nasser; Benwell, George L; Holt, Alec
    The aim of this paper is to explain a new approach for calculating spatial accessibility to primary health care (PHC) services. New Zealand and World Health Organisation (WHO) rules were used to determine acceptable levels ...
  • Neuro-fuzzy engineering for spatial information processing 

    Kasabov, Nikola; Purvis, Martin; Zhang, Feng; Benwell, George L
    This paper proposes neuro-fuzzy engineering as a novel approach to spatial data analysis and for building decision making systems based on spatial information processing, and the development of this approach by the authors ...
  • Process management for geographical information system development 

    MacDonell, Stephen; Benwell, George L
    The controlled management of software processes, an area of ongoing research in the business systems domain, is equally important in the development of geographical information systems (GIS). Appropriate software processes ...
  • Recomputing historical barometric heighting 

    Benwell, George L
    This paper discusses the method of determining heights of mountains during the original geodetic survey of Victoria. From 1840 to 1875, more particularly the 1860s, geodetic surveyors were charged with the responsibility ...
  • Spatial databases—creative future concepts and use 

    Benwell, George L
    There is continuing pressure to develop spatial information systems. This paper develops two concepts that could emerge. The first is a new spatial paradigm—an holistic model—which is less of an abstraction from reality ...
  • Spatial isomorphism 

    Holt, Alec; MacDonell, Stephen; Benwell, George L
    This research continues with current innovative geocomputational research trends that aim to provide enhanced spatial analysis tools. The coupling of case-based reasoning (CBR) with GIS provides the focus of this paper. ...
  • Spatio-temporal patterns of campylobacter contamination in freshwaters: results from the Taieri and Motueka catchments 

    Eyles, Rebekah; Benwell, George L; Niyogi, Dev; Townsend, Colin; Weinstein, Phil
    New Zealand has a history of rapid ecosystem change since the arrival of humans, resulting in a predominantly agricultural landscape. Non-point source pollution from pastoral land use causes microbial contamination of ...
  • The trustree for the visualisation of attribute and spatial uncertainty: usability assessments 

    Kardos, Julian; Moore, Antoni; Benwell, George L
    Attribute and spatial uncertainty are defined and put into context for this research. This paper then extends on a research programme which has designed a visualisation of attribute and choropleth spatial uncertainty using ...
  • Using data models to estimate required effort in creating a spatial information system 

    Benwell, George L; MacDonell, Stephen
    The creation of spatial information systems can be viewed from many directions. One such view is to see the creation in terms of data collection, data modelling, codifying spatial processes, information management, analysis ...
  • Violent crumble: do buildings stand and systems tumble? 

    Benwell, George L
    This paper introduces the notion that systems develop is not as bad as reported in the literature, but nonetheless there is some room for improvement. It sets out to enhance the outcomes of information systems development. ...
  • The visualisation of uncertainty in spatially-referenced attribute data using TRUSTworthy data structures 

    Kardos, Julian; Moore, Antoni; Benwell, George L
    This paper presents the use of hierarchical spatial data structures to visualise attribute and spatial uncertainty when using spatial information systems. This is demonstrated using spatially-referenced data from the New ...
