GIS (Geographic Information System) data modeling is a methodology for designing spatial databases. Efficient database design is crucial to efficient GIS implementation. A model is a simplification of the complexity of reality, which makes the reality more understandable and operational. The Objective of this paper is to present an overview of various data models and to evolve an approach to de...

BACKGROUND Effective environmental data management is meaningful for human health. In the past, environmental data management involved developing a specific environmental data management system, but this method often lacks real-time data retrieving and sharing/interoperating capability. With the development of information technology, a Geospatial Service Web method is proposed that can be emplo...

This paper describes the tools developed to link the SIBERIA model with a GIS. SIBERIA simulates the evolution of landforms within a catchment using digital elevation data. Integration of SIBERIA with a GIS provides easier access to the model for non-specialist users, and also extends model functionality. The complexity of the model means that integrating the two technologies using an ‘embedded...

The explosive growth in Internet-powered services has fueled the quest for finding new killer Internet-based applications. This quest has often led to applications based on Geographic Information Systems (GIS), especially in the emerging field of the Mobile Internet. Unfortunately, the traditional GIS model falls short of accommodating the requirements and needs of the Internet environment. A m...

Sharing and integrating Remote Sensing (RS) and Geographic Information System/Science (GIS) models are critical for developing practical application systems. Facilitating model sharing and model integration is a problem for model publishers and model users, respectively. To address this problem, a framework based on a Web service for sharing and integrating RS and GIS models is proposed in this...

The evaluation of potential damage of future floods is an essential part of flood management project appraisals. Analysis results reliability is an important issue when comparing flood risk reduction project scenarios. Geographic Information System (GIS) technology plays a crucial role on flood risk analyses. On one hand, the evaluation process requires data on flood hazard and on vulnerability...

This paper presents a Geographic Information Systems (GIS) based navigable 3D animation of project activities to visualise and review a construction project schedule as an alternative to the existing 4D CAD tools. Most of the commercial tools allow planners to build a 4D model but lack features like generation and manipulation of developed 4D model on a single platform. To facilitate the 4D mod...

Geographic information systems (GIS) have developed in response to a range of needs, and provide highly structured environments for working with particular classes of information. The environment and structure of a GIS is defined by its data model; the paper reviews the basic data models of GIS. The needs of discrete transportation modeling have led to a number of extensions of the basic data m...

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...
