A GIS (Geographic Information System), is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data. In other words, GIS is the merging of statistical analysis, database technology and cartography that can be integrated into any enterprise information system framework. But despite all these advantages, geographic information system...

The idea of GIS used by citizens in exercising democracy, dubbed public GIS, involves the use of GIS tools to help laypeople understand the spatial consequences of proposed projects and actions effecting their communities. The widening use of the Internet creates the opportunity of elevating GIS to a truly public decision making tool by making it accessible regardless of spatial and temporal co...

A number of approaches for integrating GIS and qualitative research have emerged in recent years. Despite significant growth in public participation GIS (PPGIS) literature since the 1990s, little engagement by e-government scholars is evident in the extensive scholarly PPGIS debates. To fill this void, recent trends in PPGIS adoption by local governments are analyzed. Three waves of GIS are ide...

The Open GIS Consortium (OGC) has proposed a standard for the software architecture of geographic information systems (GIS) in order to enable interoperability among different GIS products. The so-called Abstract Model does not support spatial constraints yet, although most of the later proposals of GIS conceptual data models already do. This paper presents an extension of OGC’s Abstract Model ...

Geographic Information Systems (GIS) is a kind of computer software that allows people to work with digital maps in a fast and flexible way. In the past decade, more and more geography teachers have become interested in the possibilities of using GIS in secondary education. However, teaching with GIS is complex, and little is known about how to do so in an optimal way. Therefore, an Educational...

Despite the progress in critical GIS research in recent years [1], geographical discourse is still dominated by dualist thinking that understands GIS largely as a tool for quantitative or empiricist spatial analysis. This dualist understanding of geographical methods which was partly fuelled by the fierce polemics between critical geographers and GIS users/researchers sparked off in the early 1...

Grid Geospatial Information Service (Grid GIS) system aims to study and develop grid-based uniform spatial information access and analysis system. Data resources of Grid GIS include not only original and traditional GIS data but remotely sensed data. Analysis function is made up of not only single spatial information access but complex and quick data processing. The Grid GIS system can provide ...

Making a business case for GIS in local government is a complex task for two main reasons: first, a GIS implementation can range from a single, well-defined application in one department to a corporate multi-purpose GIS; and, second, local authorities are complex organisations currently facing major pressures for change considerable uncertainty about their future structure and role. The purpose...

Although geographic information system (GIS) education has been spread widely, it becomes increasingly apparent that twodimensional maps cannot be precisely present multidimensional and dynamic spatial phenomena. It seems that merging GIS and Virtual Reality (VR) is a way to deal with these issues in terms of GIS classroom teaching. Virtual learning environment is the simulation of teaching met...

The evaluation of land quality plays an important role in the study of land resources. Some software of GIS was applied to evaluate land quality in recent years. There is some limitation in Appling GIS to evaluate land quality directly. GIS combined with MCE (Multi-Criteria Evaluation) can eliminate limitation existing in using GIS singly. In this thesis key technology of evaluating land qualit...
