For the last 15 years, designing 2D databases has benefited from new or extended formalisms proposed by the GIS research community. However, three-dimensional representations have been significantly more frequent in the recent years, especially in 3D computer graphics and in 3D GIS. In spite of this fact, there exist a lot of confusion in fundamental notions and there has been insofar no propos...

As the presentation and development of “Digital Maritime” and “E-Navigation”, Aids to Navigation (AtoN) is more and more important to marine navigation safety. In recent years, great advances have been obtained in AtoN applications. However, most domestic AtoN setting systems are based on 2D electronic chart which can not represent AtoN visual effects and its complex "interactive visual effects...

With the development of GIS, its applications concern with different domains, such as geography, mapping, urban, traffic, geology, mine, military and so on. 3D GIS is the research hotspots in the domains of city, geology, mine etc. 3D GIS in city has been developed more quickly, CyberCity, for example is a smart application of 3D GIS, but it is slow in subsurface engineering because of its comp...

Three-dimensional (3D) city models present and animate all urban features such as buildings, highways, parking areas bridges on computer platform. 3D city reconstruction helps to set a base for reorganizing current city structures and it is an important requirement to help future decision-making process. A 3D model shows what is going to change and happen at the end of a new design. It explains...

In this study, a knowledge management based Decision Support System has been suggested. By collecting the data of people, event and properties of building, a 3D navigation system has been developed to support building management and users during the extraordinary circumtances. Most of the current navigation systems are still in the 2D environment and that is insufficient to visualize 3D objects...

This paper explores a method for creating large-scale urban 3D models using Historical GIS data. The method is capable of automatically generating realistic VR models based on GIS data at a low cost. 3D models of houses are created from polygon data, fences from line data, and pedestrians and trees from point data. The method is applied to the Virtual Kyoto Project in which the landscape of the...

3D space registration and visualization has become an imperative need in order to optimally reflect all complex cases of rapid urbanization of property rights and restrictions. Besides, current technological advances as well as the availability of sophisticated software packages (proprietary or open source) call for 3D modeling especially in the GIS domain. Within this context, GIS community’s ...

SUMMARY This study aims at urban 3D features modeling/rendering system architecture design and its prototype implementations on 3D mobile and web 3D application. Mobile 3D is a cutting-edge technology. However, platforms and devices for mobile 3D GIS technology manipulating geographic data and information provide some limitations to design and implement. Despite, emerging standard mobile 3D gra...

The method of how to abstract reality into a two-dimensional map is already mature, but with the development of three-dimensional GIS, we have to be up against the problem how to describe the reality in a 3D means. Although there are already many 3D GIS software and systems from various corporations, the standard for 3D abstraction and description of real world is still poor. In the paper we ha...
