“…Thus, the use of virtual reality, which gives the user the ability to change viewpoints and models dynamically, can help overcome the static limitations of analysing and visualizing geo-referenced data (Diotin and Kooy, 1995). Fairbairn and Parsey (1996) also added that virtual reality is a technique that enables users to move towards a finer emulation of the complexities of the real world. In addition, Baker and Wickens (1992) indicated that virtual reality provides an interactive environment, which is well suited to supporting the interactive presentation of scientific datasets.…”

Visualization methods in the analysis of geographical datasets are based on static models, which restrict the visual analysis capabilities. The use of virtual reality, which is a three-dimensional (3D) perspective, gives the user the ability to change viewpoints and models dynamically overcomes the static limitations of two-dimensional (2D) views. Based on this, the paper highlights the importance, characteristic and classification of Virtual Reality as a tool in data visualization. The paper also outlines real life applications of Virtual Reality as a means of visualization. The distinction between Virtual Reality and Cartography is also presented. This paper also attempts to outline the Virtual Reality Modelling Language (VRML), which is a scene description language for developing Virtual Reality.

“…The representation of reality, in conventional planar maps, includes the overstepping, in which the users know very well its difficulties, of representing the real 3D nature of a landscape using a planar tool: the map (Fairbain Prisley, 1997). In Virtual Reality the characteristics of cartographic visualization are extended with the use of advanced tools: moving in the 3rd and 4th dimension, creation of illusion of gravity independence, and animation with the ability of spatial immersion.…”

“…The Virtual Reality has stronger analytical ability, for spatial data, that the conventional cartography has (Fairbain Prisley, 1997). It emphases in the natural role of cartography by giving the ability of producing new ways of spatial data visualization, not only for informative purposes and users interaction, but also to extent the static model of the map into a dynamic environment with embedded interaction tools and decision making.…”

Virtual reality: The non-temporal cartographic animation and the urban (large) scale projects

The evolution of digital technology has placed cartography in a dialog on questions concerning the new abilities, its form and prospective. The cartographic presentation in three dimensions has as a basic feature: the simulation with the ''natural'' ability of understanding the space.One of the problems that arose in virtual environments refers to the use of scale in relation to the analysis and the study of space. This relation of geographic analysis and cartographic tools is strictly defined in traditional cartography, but in the virtual cartographic environment the rules of optical understanding and measurement of space are defined by an arbitrary free moving of the sight, that prescribes the natural vision and therefore the perception of the specific space.In close relation with the cartographic motion is the cartographic visualization of the time and the relevant techniques: splitting of time, creation of motion frames, timing, rapidity, motion pattern, etc.The specific work describes, through specific examples that focus mainly on urban areas, methodological and technical approaches concerning the concept of time and scale problems in virtual cartography, but mainly contributes in the ongoing scientific dialogue concerning the theoretical documentation of Virtual Cartography.Finally,we regard Computational Intelligence as a comprehensive and effective algorithmic platform for mechanisms of Virtual Reality.

“…From a performance point of view, it may be necessary to apply Level-Of-Detail (LOD) techniques that automatically adapt the complexity of the geometric model to what can be displayed in real-time, but still looks the same as the full geometry (Fairbairn and Parsley 1997). Several techniques are available: the model can be geometrically simpli® ed as a function of the viewing distance (objects that only cover a few pixels can be represented by a few polygons; a large set of small elements can be represented by a transparent volume, etc.…”

To support 3D GIS interaction within VR-environments we propose a multi-view approach based on three types of visualization: plan view, model view and world view. The visualization in these views ranges from a conventional map, through a partly symbolic and simpli® ed 3D representation to a full immersive and photo-realistic 3D display. The views can be used simultaneously or intermittently, and each provides a repertoire of interaction possibilities that are aptÐ but not necessarily limitedÐ to that view. We are currently developing a 3D GIS&VR system (Karma VI) based on existing GIS and VR technology that uses the three views to support the design, development and presentation of large infrastructure plans in The Netherlands. Operational use of this system showed that the multi-view approach leads to a more sophisticated understanding of those plans.
