A key to a successful GIS in organizations
Summary
Many GIS organisations or organizations with GIS technology tools are faced with problems in implementing GIS technology at their work place. In most cases, GIS fails because the professionals and managers who allocates resources are simply not aware of what drives GIS technology, and as a result they ignore the core components that leads to a successful GIS implementation.
Introduction
The term ‘geographical information systems’ describes a technology. It’s a complex technology, and its successful application requires the linking of a number of technologies most of which have been developed independently of the GIS world.
GIS deals not only with technology, but also with the inputs to and the outputs from that
technology, which makes it a field of study. In order to properly use GIS, we need to understand what is involved in making it work successfully. What is involved is not simply technology but the whole context of its use. In summary, this article brings forward the idea that there are complex ramifications to the use of GIS technology.
When justifying GIS nowadays, experts need to strengthen the importance of the GIS components, namely technology, data, organisations, methods and body of ideas. This is because these are the core base of GIS that match the vision and commitment of the administrative and technical levels concerned, which should then be balanced against the technological and organizational investment needed in developing the necessary GIS infrastructure.

Web-based GIS for mapping voting patterns
Web-based GIS for mapping voting patterns at the 2004 Australian federal election
This paper describes a Web-based geographical information system (GIS) for mapping voting patterns, at the 2004 Australian federal election, at the polling booth level. The locations of polling booths are geocoded and linked with national digital datasets, including the 2001 census. The Web-based GIS can generate maps displaying patterns of voting for political parties across polling booths with overlays of data showing the demographic and socio-economic characteristics of populations within the surrounding polling booth catchments. A classification functionality consisting of equal interval, quantile, median-based natural breaks and location quotient may be used in order to generate different map displays. The Web-based GIS has been developed as an information dissemination and analysis tool to not only benchmark voting outcomes but also to visualise relationships between voting patterns and local demographic and socio-economic data.

GIS software selection
GIS software selection: a multi criteria decision making approach
Building a new GIS project is a major investment. Choosing the right GIS software package is critical to the success and failure of such investment. The problem of selecting the most appropriate GIS software package for a particular GIS project is a multi criteria decision making (MCDM) problem. Solving this problem requires consideration of a comprehensive set of factors and balancing of multiple objectives in determining the suitability of particular software for building a defined GIS application. In this paper a MCDM technique, analytic hierarchy process (AHP), is used to assist system developers to select the most appropriate GIS software for a specific application. An AHP decision model is formulated and applied to a hypothetical case study to examine its feasibility in solving GIS software selection problem. The use of the proposed model indicates that it can be applied to improve the decision making process and to reduce the time taken to select a GIS software.
