government task, such as Beijing, Shanghai, Guangdong,
Hainan, Shaanxi, Shanxi, Jiangsu, Zhejiang, Xinjiang, Henan,
Shandong, etc. These provinces paid more attentions on
fundamental geospatial data resources and applications. For
instance, Digital Shaanxi Geospatial Information Fundamental
Framework (DSGIFF) was approved in 2001 by the Shaanxi
Provincial Government. It consists of 8 components: geospatial
data acquisition and database construction, GPS applications,
remote sensing facilities, standards drafting, legal system,
coordination mechanism, research and development and pilot
applications.
There are more than 30 cities commencing the construction of
Digital City Geospatial Framework sponsored by SBSM, such
as Weihai, Wenzhou, Jiaxing, Xi’an, Qianjiang, Taiyuan,
Kuitun, etc. They are focused on large scale geospatial data sets
including 3D city models, utilities and more daily life
information to support more Location Based Service (LBS)
applications. Digital City Geospatial Framework is still mainly
focused on the city itself similar to the concept of cybercity,
The whole area of its administration is not yet covered to
include the townships and countryside. There are also some
counties starting digital region geospatial framework to support
integrated urban and rural development. Digital Beijing
Geospatial Framework has been implementing to play a very
important role in the 2008 Olympic Games in Beijing.
8. CONCLUSION REMARKS
SDI and Digital Region are new matters to China and the world.
China is pushing forwards the construction of DCGF, however
this is still lack of matured technology, standards system,
updated datasets and effective coordination mechanism. The
user needs are great but the service capacity is not yet suitable
enough. The situation of isolated information islands has to be
overcome so as to supply the society with rich accessible
geospatial information resources.
There are still some key issues to be solved accordingly. The
first issue is the effective coordinating mechanism to promote
the information resources sharing. The second issue is the small
amount of financial input to be increased. All the technology,
data and human resources development needs huge input. The
third issue is the standards needed to be revised and ISO
standards to be adapted. The fourth issue is the applications to
be widen to cover all social and economic sectors.
Besides the Law of Surveying and Mapping and related
regulations, a legal system should be strengthened to reflect the
geospatial sharing. The legal state of Digital China Geospatial
Framework must be erected to avoid replication and. Much
more international cooperation and technical exchange should
be sought and encouraged to promote the development of
DCGF. The achievements of DCGF will not only benefit the
government but also the community to serve as the unique
geospatial information reference.
