This paper reports a current GIS research project which is being undertaken in the Tweed area of north coast New South Wales. The project focuses on drainage management problems which are of increasing concern for land and environmental management for the sugar industry in this area. GIS network capabilities are employed with enhancements of specific needs for the drainage simulation. Natural a...

This papers aims to establish a road traffic management system for Dalian based on GIS and WebGIS technologies. First, based on the map of Dalian, digital road network database is constructed within GIS, and visualized database management programs are developed to realize a Graphic Use Interface (GUI) style query and maintenance of road and traffic information. Further, in order do network anal...

Application of Geographic Information Systems (GIS) in construction disaster relief planning is presented. A case study of GIS developed for Fulton county in the state of Georgia is presented. The project identifies potential resource allocations and accessible roads network using TranCAD GIS computer program. This model could be used for a disaster relief project to identify the available reso...

The advantages of ‘Distributed GIS’ have long been realised by GIS practitioners and researchers, for its strengths of system flexibility, reliability, scalability, processing efficiency and resources sharing. However, due to the complex network architecture and software structure, current distributed GIS (DGIS) still cannot fully accommodate distributed, heterogeneous and speedy development in...

This article describes advantages and disadvantages of federal government centralized geographic information networks and decentralized peer-to-peer geographic information networks as they pertain to North American Indian tribal governments and communities. Geographic information systems (GIS) are used by indigenous groups for natural resource management, land claims, water rights, and cultural...

Available ubiquitous networks that make use of small mobile devices like PDA and cellular phones, offer varied possibility of use by new generation application softwares. These applications utilize the available networks and devices to help users in their daily activities in different geographical areas. These set of applications constitute location based services and combine Geographic Informa...

This paper focuses on the deployment of Geographical Information Systems (GIS) and Spatial Data Infrastructures (SDI) within local government in Thai Provinces. GIS has been used extensively within local government and many countries have undertaken SDI initiatives, but these tend to focus at the national level, failing to address the local deployment issues. By their nature as infrastructures,...

Much of the success of location-based applications comes from using spatial analysis in query processing and graphic visualisation. Recently, with the arrival of miniature and inexpensive GPS receivers and cellular phones, new horizons have been opened for these applications. The mobile telephone and Internet technology within the GIS environment has fostered new applications with higher degree...
