ABSTRACT: 
It is the intention of this paper, to stimulate the scientific as well as the public interest in virtual spatial visualization. 
Therefore this paper deals with fundamentals for virtual spatial data presentation, starting with results, showing the advantages of 
spatial image data interpretation. Additional basics dealt with include a systematic and complete(!) synoptically overview for 
stereoscopic techniques, according to the state of the art. 
Stereoscopic techniques in this sense mean full virtual spatial visualization techniques only, while data presentations limited to 
perspective or so called 2.5D projections are not part of this investigation. 
Beside well established 3D visualization Technologies, based on stereoscopes, anaglyphs, polarized glasses, liquid crystal shutters, 
chromadepth glasses etc., it is liked to emphasize, the dynamic Nuoptix method, according to PULFRICH and in particular the 
improved solid state Felix-3D promise a great future for both, the scientific as well as the public 3D visualization. 
It is liked to emphasize, a portable light staff (digital) camera, preferable with remote control, for extreme low altitude photography 
very successfully has been applied for 2D image mosaics as well as for 3D visualization of antique objects in the ancient city of 
Patara(Turkey). This rather flexible light staff camera method promises a great future, not only under expedition constraints. 
As a first result this paper deals with at least 10 topics, which are still a matter of research, e.g., the optimum base length for close 
range stereo photography. 
An attempt has been carried out, systematically to define remaining research Gaps in 3D visualization, which stimulates for further 
progress in this field. 
1. INTRODUCTION 
In the digital age the importance of spatial data presentation and 
visualization is increasing for tremendous applications, like 
- for 3dimensional viewing of synthetic vector data based 
stereo mates for a better understanding and interpretation 
of Monument Information System (MIS) data, including 
vector data based sketches basic and thematic layers for 
synoptically as well as for reasons, concerning detail 
precision, 
- for the stereoscopic presentation of architectural and 
archaeological models, currently in particular increasingly 
derived from laser scanners etc.. 
- for practical improvements from a  3dimensional 
interpretation of MIS related stereo mates for, but not 
restricted to close range image maps. 
The main benefit of 3dimensional data presentation in general is 
the still underestimated gain of a complete additional 
dimension. 
This means, the 3D product is the "long-range vision" for the 
provided product of close range imaging to be used for the 
broad spectrum of close range Deliverals. 
For MIS devices allowing a temporary processing of the stereo 
mates there is no need for a permanent additional storage. 
This paper concentrates on basics of virtually 3dimensional 
data visualization, but neglects perspective or so called 2.5 
dimensional data presentations. 
As a result of fundamentals of virtually spatial data 
presentation, including the aids for stereoscopy it deals with the 
complete list for 3D visualization techniques. 
It is liked to emphasize, from a consequently dealing with the 
principals of spatial data visualization, even the future of the 
whole computer industry might change. 
Here namely the so called FELIX -3D with a solid state 3D 
screen seems to become a real candidate for a new spatial PC 
generation in order to replace or to complete the 2dimensional 
screen generation. 
The FELIX-3D solid state is the successor of well known 3D 
cylindrical Plexiglas tube, both suited for the presentation of 
3D Laser based models, to be generated in color and in real 
time, for a direct autostereoscopic visualization, which means, 
for unaided eyes. 
After dealing with the essentials of advanced 3dimensional MIS 
data presentation it is consequently reported on methods for 
stereoscopic viewing of MIS data and on a procedure for a 
systematic basic research in spatial data visualization. In this 
context it is shown, this moving back to the basics of spatial 
data visualization is required and gains a surprising potential for 
further research. As a first result, there are defined 11 research 
topics in this particular field of spatial MIS data research.
