In this paper we describe the application of analogical structure matching techniques to the domain of Geographic Information Systems (GIS). Automatic categorisation of map data into roads, buildings etc. is currently based on isolated objects. We describe how identifying analogous clusters of objects can categorise ambiguous polygons by introducing context into the categorisation process. We d...

It is possible to eliminate some of the traditional problems with GIS implementation by changing the model of space used. The Voronoi spatial model has bee used as the basis of a set of core GIS or spatial operations, with encouraging results. It has been implemented in a PC environment so as to leave as much flexibility as possible for the designer of any particular application. Examples inclu...

A need exists within urban planning for techniques to promote sustainable policies and developments for this to become possible, we need to enhance and facilitate stakeholder understanding and involvement in decision making and in monitoring the impacts of management policies. GIS (Geographical Information Systems) are commonly used as planning and analysis tools in developing countries, while ...

Web GIS (Geographic Information Systems) service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user-interface. But, early systems don’t support open environment and interoperability. It is difficult to access diverse data sources, which provide each spatial data format. And, these systems have the difficult of upgrading the function and redu...

From Maps to Information Systems Track: New Technology and Technology Integration Author(s): William Holland It has been said that two-thirds of a GIS is information systems. Spatial information--maps-serves as only part of the input and output of a GIS. That said, the real power and benefits of GIS are not solely map production but rather business process improvement through systems integratio...

This paper examines and evaluates the application of GIS for cyclone disaster risk management, focusing on observations from a real-time emergency management disaster scenario held in Mackay in far north Queensland, Australia. Results from scenario observations and post-scenario interviews with risk managers highlight the limitations of GIS for real-time disaster planning. Limitations include t...

Geographical semantic representation, which aims at enhancing geospatial data model and facilitating information sharing and exchange, has been a hot topic in the realm of geographic information science. The research summarized here is to advance a geographical semantic representation framework to support geo-collaboration, focusing on how to take full advantage of Ontology and Web Services tec...

Geographical Information Systems (GIS) are often used to assess and monitor the environmental impacts caused by mining activities. The aim of this work was to develop a new application to produce dynamic maps for monitoring the temperature variations in a self-burning coal waste pile, under a GIS open source environment—GIS-ECOAL (freely available). The performance of the application was evalua...

Research on GIS applications in the real world context has to be strengthened besides developing GIS application software itself. An ecologically important field of applications is the integration of GIS technology in wetlands research. Documentation, analysis and modelling of spatial data of wetlands and lakes supports ecological research and planning to the highest extent. High resolution ter...

At first glance, the domain of health is no typical area to applicate Geographical Information Systems (GIS). Nevertheless, the recent development clearly shows that also within the domains of environmental health, disease ecology and public health GIS have become an indispensable tool for processing, analysing and visualising spatial data. In the field of geographical epidemiology, GIS are use...
