Air pollution problem in the Pearl
River Delta (PRD) region, caused by the fast increasing
industrial development, has become the top environmental issue
of Hong Kong and other major cities. Air pollution is not a
local problem and never stop at regional boundaries. Hence,
developing cooperative measures by government officers,
scientists as well as general public in the region is the only
possible way to tackle the problem.
Led by Prof. Lin Hui, researchers
of The Chinese University of Hong Kong and the Sun
Yat-sen University jointly developed the Collaborative
Virtual Geographic Environment (CVGE) platform. This
platform system aims to provide an interactive collaboration
environment for the scientists, officers and general
public carrying out joint investigations of regional
air-pollution problems.
We adopted multiple-sources air
pollution data integration, satellite imagery, geographic
information systems and processing models, virtual reality,
Wide-Area Network etc. We also integrated the platform system
with atmospheric circulation model and air pollution dispersion
model. The platform provides comprehensive modeling capabilities
and geographic analysis for air-pollution studies. Mostly
important, this is a collaborative platform for scientists,
geographers, computer simulation technologists as well as
general publics. The different interest groups share their
knowledge, discuss, analyse and even forecast the impacts of air
pollution problems simultaneously. This platform is essential to
the timely, thoughtful responses to the regional environmental
problems. Moreover, the three-dimensional display system helps
government officers as well as public understanding air
pollution transportations and dispersions simulation. |

Geo-collaboration on air pollution simulation and
analysis |
We have completed this two-year
project in 2009. Our present objective is promoting the
Collaborative Virtual Geographic Environment Platform to the
industry. We can also further extend the platform system for
specific applications such as emergency response and decision
support, micro-scale air pollution control, sustainable urban
development as well as public health assurance. |
