The popularity of Internet technology has brought about some fundamental changes in the field of GIS. Internet GIS is emerging as a new technology to access, process, and disseminate spatial information over the Internet. Internet GIS cover a much wider audience than the traditional GIS. This raises many issues that are distinct from traditional desktop GIS, such as easy access, webcompatible u...

Interdisciplinary research projects with environmental focus need an information technology which is capable of describing the flow of minerals and other substances with respect to space and time. Especially time dependencies are of great interest in many environmental studies, where changes can often be shown only via trend analysis of time series. A suitable technology must also supply method...

The significant function of GIS technology in promoting the railway development in this information era is now attracting great attention from the Ministry of Railway and the State decision-making institutions of the P.R.China. However, until present, the GIS has not been economised on the Chinese Railway. Discussions have been made on the several critical issues in building up the railway GIS....

The geographic context is essential both for environmental research, and for policyoriented environmental management. Geographic information systems are as a result increasingly important computing applications in this domain, and an understanding of the underlying principles of geographic information science is increasingly essential to sound scientific practice. The review begins by defining ...

BACKGROUND Geographic information systems (GIS) are increasingly recognized tools in maternal health. OBJECTIVES To evaluate the use of GIS in maternal health and to identify knowledge gaps and opportunities. SEARCH STRATEGY Keywords broadly related to maternal health and GIS were used to search for academic articles and gray literature. SELECTION CRITERIA Reviewed articles focused on mat...

The integration of GIS and multicriteria decision analysis has attracted significant interest over the last 15 years or so. This paper surveys the GISbased multicriteria decision analysis (GIS-MCDA) approaches using a literature review and classification of articles from 1990 to 2004. An electronic search indicated that over 300 articles appeared in refereed journals. The paper provides taxonom...

In the Earth science disciplines, both the observational instrumentation and numerical forecasting technology used to generate data are improving so rapidly that the techniques available to manage and use the resultant datasets are struggling to keep pace. A notable example is represented by the atmospheric science discipline. As observational and model output datasets in the atmospheric scienc...
