3D Urban Visualization for Cybercity: from Outdoor to Indoor 
LI Deren     

ABSTRACT 

CyberCity is one of the most important research topics in urban information
infrastructure. Until now, CyberCity is mainly applied for the outdoor scenes
including natural and cultural objects e.g., DEM, rivers, roads, vegetation and
building surfaces. In these applications, users can walk around the created 3D
environment, visit city landscape, and implement some operations such as
querying, editing and analyzing in the outdoor 3D scenes. However, there is
little research on the integration of outdoor and indoor scenes together. The
real world that people live and work is an integrated environment of outdoor
and indoor. Therefore, the further development of CyberCity should be a
seamless integration of the outdoor and the indoor scenes in CyberCity. This
presentation will present our effort in this topic, including key techniques,
such as data management method and dynamical visualization method for the
outdoor and the indoor scenes, comparison of visualizing the indoor scene with
the outdoor one.

Biographical Sketch.

Prof. Dr. Deren Li is committee board of the scientific commission of China,
academicians of both the Chinese Academy of Sciences and the Chinese Academy of
Engineering, and academician of the Euro-Asia International Academy of Science.
He is now President of the Chinese Society of Geodesy, Photogrmmetry and
Cartography and Director of the National Laboratory for Information Engineering
in Surveying, Mapping and Remote Sensing (2000-present).

Prof. Li served as president of Wuhan Technical University of Surveying and
Mapping (1996-2000), was selected as Committee of the 9th Chinese People's
Political Consultative Conference (CPPCC), and was honored as National Level
Young and Middle-aged Expert with Outstanding Contribution.

Dr. Li earned his Ph.D. in the error theory and data analysis from Stuttgart
University, Germany in 1986. Prof. Li has been published 8 books and over 350
papers and advised 64 MSc and 83 PhD, and won more than ten international and
national level awards and prizes.

In the 1980s, Prof. Li mainly specialized in the studies of observation errors
and processing methods. His posterior variance estimation-based iteration
weighted method for bundler location has been recognized and named "Deren Li
Method" internationally. In 1985, he completed theoretical research on the
separability of model errors. This scientific result was honored
"Scientifically Solved One Hundred-Year-Baffling Problem in Geodetic Science".
As a result, he received 1988 Best Paper Award of the German Society and Remote
Sensing, and Hansa Luftbild Award. From 1990 up to now Prof. Li has
concentrated on his research in spatial information science and technology with
specific emphasis in remote sensing (RS), global positioning system (GPS) and
geographic information system (GIS). He has made unique and original
contributions to the scientific areas of theories and methods in such as high
precision photogrammetric positioning, GPS aero-triangulation, analysis and
processing of SPOT imagery, mathematical morphology and its application in
spatial databases, theories of object-oriented GIS, image understanding and
automatic photo-interpretation, multi-media communication and mobile mapping
systems, etc. The researched results have significantly stimulated the progress
of the industrialization toward the high and new technologies.
