BACKGROUND Data analysis in community health assessment (CHA) involves the collection, integration, and analysis of large numerical and spatial data sets in order to identify health priorities. Geographic Information Systems (GIS) enable for management and analysis using spatial data, but have limitations in performing analysis of numerical data because of its traditional database architecture....

This paper studies the development of GIS from a new point of view, which both from the accumulation of GIS scientific articles and the evolution process of GIS using co-citation analysis. After 10 years’ slow development from 1977, the number of GIS scientific literature began to increase rapidly since the early 1990s. By using the newly developed information visualization technology, the auth...

We present a novel GIS, Real Space GIS, which is a 2D & 3D integration GIS. Real Space GIS is based on Real Space which is 3D geographical space and 2D map space which is based on geographical sphere or ellipsoid comparing to Paper Space GIS which is based on traditional Paper Space based on paper map coordinates. Real Space GIS mainly integrates data structure, data model, data storage, data v...

The functionality of spatial process analysis is the foundation of GIS’s comprehensive application . To realize such a goal. it is desirable that not only the data model of GIS can represent the datasets needed by spatial process models, but also GIS is able to do multitemporal spatial analysis. But most of current GISs are static in essence, they cannot represent temporal information and tempo...

The early optimism surrounding GIS has now faded. Few GIS implementations have lived up to expectation. The most successful have been those at the operational level where their main role has been to replace paper maps with digital ones. However, as the cost of GIS implementation falls and spatial data becomes more readily available there is a need to consider the future of GIS and spatial analy...

This paper presents an endeavour of integration of GIS (Geographical Information System) and BIM (Building Information Modelling) for indoor geovisual analytics. The merits of two types of technologies, GIS and BIM are firstly analysed in the context of indoor environment. GIS has well-developed capabilities of spatial analysis such as network analysis, while BIM has the advantages for indoor 3...

The catalytic boost of critical mass usage of the World Wide Web (WWW) has brought about the shift in the traditional geographic information systems (GIS) paradigm and engendered new challenges and opportunities. The traditional GIS paradigm involves the use of huge databases and large expensive GIS software packages confined to local disks. The new paradigm, however, enables geospatial data to...

Both geographic information systems (GIS) and network analysis are burgeoning fields, characterised by rapid methodological and scientific advances in recent years. A geographic information system (GIS) is a digital computer application designed for the capture, storage, manipulation, analysis and display of geographic information. Geographic location is the element that distinguishes geographi...
