Visualising attribute and spatial uncertainty in choropleth maps using hierarchical spatial data models
This thesis defines a novel and intuitive method to visually represent attribute uncertainty, and spatial boundary uncertainty generated from choropleth maps. Like all data, it is not possible to know exactly how far from ... -
Spatial information systems for wildlife conservation management: Taiaroa Head royal albatross colony
The breeding colony of Northern royal albatross (Diomedea sanfordi) at Taiaroa Head is the only mainland breeding colony of any albatross species. Although it represents only a small proportion of the total population of ... -
Incorporating a new computational reasoning approach to spatial modelling
Decision support systems, statistics and expert systems were some of the mainstay techniques used for modelling environmental phenomena. Now modelling systems utilise artificial intelligence (AI) techniques for the extra ... -
Investigating complexities through computational techniques
This article outlines similarity applied to the general environment and geographical information domains. The hypothesis is if physical and social sciences manifest similar amenities, then similarity would be a generative ... -
Data sharing using the X.500 directory
Sharing geographical data sets is highly desirable for economical and technical reasons. In this paper the author describes the development of an agency for sharing geographical data which is based on the use of the ISODE ... -
Development of a generic system for modelling spatial processes
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 ... -
Environmental decisions with spatial process modelling
This paper first describes the difficulties inherent in supporting a class of environmental problems, those involved in Regional Environmental Decision Making. A set of conceptual criteria are presented along with discussion ... -
User defined spatial business rules: storage, management and implementation — a pipe network case study
The application of business rules as a means of ensuring data quality is an accepted approach in information systems development. Rules, defined by the user, are stored and manipulated by a repository or data dictionary. ... -
Recomputing historical barometric heighting
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 ... -
An object repository model for the storage of spatial metadata
The design of spatial information systems has traditionally been carried out independently of mainstream database developments. It is contended that the adoption of mainstream database design techniques is important to ... -
Neuro-fuzzy engineering for spatial information processing
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 ... -
Using data models to estimate required effort in creating a spatial information system
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 ... -
Spatio-temporal and object visualization in rugby union
The use of computer software as an aid to rugby, and sports coaching in general, is becoming increasingly utilized. Videoed sport is the most widely used form of raw data for sports analysis, though it is currently not ... -
A taxonomy of spatial data integrity constraints
Spatial data quality has become an issue of increasing concern to researchers and practitioners in the field of Spatial Information Systems (SIS). Clearly the results of any spatial analysis are only as good as the data ... -
First experiences in implementing a spatial metadata repository
Integrated software engineering environments (ISEE) for traditional non spatial information systems are well developed, incorporating Database Management Systems (DBMS) and Computer Aided Software Engineering (CASE) tools. ... -
The derivation of thematic map layers from entity-relationship data models
Semantic data models comprise formally defined abstractions for representing real world relationships and aspects of the structure of real world phenomena so as to aid database design. While previous research in spatial ... -
Spatial databases—creative future concepts and use
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 ... -
GIS maturity and integration
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 ... -
Process management for geographical information system development
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 ... -
The use of a metadata repository in spatial database development
Database schemas currently used to define spatial databases are deficient in that they do not incorporate facilities to specify business rules/integrity constraints. This shortcoming has been noted by Günther and Lamberts ...
