Visualization has become an integral part in many applications of GIS. Due to the rapid development of computer graphics, visualization and animation techniques, general-purpose GIS can no longer satisfy the multitude of visualization demands. Therefore, GIS have to utilize independent visualization toolkits. This article examines how visualization systems can be used with and integrated into G...

The U.S. Army Integrated Training Area and Management (ITAM) program focuses on the sustained use of training and testing lands. The application of GIS within the program provides for the effective integration of stewardship principles into training land and conservation management practices. To assist in managing the program’s vast GIS resources, an enterprise GIS is currently being implemente...

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...

Component Based Software Engineering has one main sole motive of making the development process of software systems as easy as possible and to achieve this objective work needs to be done in previous systems to identify the concerns and limitations which can be overcome using this software engineering based approach. In this paper to support concept of component based system a domain is chosen ...

Child Health Improvement through Computer Automation (CHICA) is a computer decision support system (CDSS) that interfaces with existing electronic medical record systems (EMRS) and delivers "just-in-time" patient-relevant guidelines to physicians during the clinical encounter and accurately captures structured data from all who interact with the system. "Delivering Geospatial Intelligence to He...

Web-GIS development often forces application domain experts to learn the programming languages and the complex frameworks adopted, thus reducing their productivity As a solution to this issue, we present a visual environment, named WGBuilder, which supports unskilled users in the construction of Web-GIS applications. By performing a set of predefined actions, they specify the customization requ...

This paper discusses the design of formal theories of geographic space for the application in Geographic Information Systems. GIS software is an implementation of formal theories of geographic space. The notions of formal theories are introduced and discussed in the context of examples from the GIS ®eld. Our approach is an application of the general framework of formal theories to the special c...

There has been considerable interest in the development of analysis techniques for Geographical Information Systems (GIS). This includes such normative spatial models as vehicle routing models, districting and turfing models for dividing up land into territories for schools, sales/service, and voting, and location models for identifying sites or patterns of sites to provide service accessibilit...

The security model proposed for the Geographic Information Systems (GIS) is a data, which is capable of visualizing technology and has the capability to apprehend, cache, verify, amalgamate, engineer and exhibit data with the help of digitized maps. It has enormous applications in the field of engineering, business management process, communication both in the private and public regions. A GIS ...
