This paper proposes integration of different technologies, techniques and standards to improve the efficiency of 3D mobile GIS applications. The paper describes different challenges that developers face while developing a 3D mobile GIS application. It then investigates different solutions to resolve the problems. Integration of client/server architecture and web services technologies together w...

Geographical Information Systems (GIS) are routinely used by public and private organisations and enterprises as well as lay persons. It is becoming an infrastructure and a preconditioning web implicitly embedded in our information society. Using a GIS is no longer a specialist endeavor. It is a daily activity of non-specialist, with or without being aware of it. This of courser changes the Wor...

Currently available GIS Web-based applications lack an interface for complex query construction. The rst reason for this is the state-less nature of the HTTP protocol. The second reason addresses the more general problem of a deenition of a new family of high level, user friendly GIS query languages usable by people that are not GIS specialists. This contribution describes the \Geographical Ant...

Urban development significantly changes constructed land across both urban and rural areas around the world in recent years. It is vital to keep constructed land data "fresh" for its application and development. Change detection with remotely sensed imagery is an effective way to updating land cover in large area. In this paper, the updating requirements of constructed land in large area are an...

The distributed spatial information system has been proposed as one of infrastructures for the development as a scientific research park in Kyushu University, Japan. The system is based on an autonomously-distributed database model with the geographical information system (GIS) technology. The GIS node, which is an important element of the system, is composed of spatial data storage, Web-based ...

The utilization of urban green zones forms a major part of urban sustainability in the context of the improvement of quality of life of the citizens. Within the policy for sustainable management of urban green zones, the tools that are used effectively are new technologies such as web databases, web DSS, GIS and environmental impact prediction model. This paper presents the geodatabase, which w...

SUMMARY The Web-based 3-D GIS would be the most appropriate tool for decision-maker of land management and development. Because, it provides with not only the basic GIS functions, e.g. the positioning and the measurement of distance and area, but also more realistic landscape and architecture detail. It also gives the user an immersive virtual reality environment through the Internet that is ra...
