ABSTRACT:
This paper discusses the construction of urban spatial data infrastructure, taking Ganzhou for example. First we set up a organization
that manages and harmonizes spatial data, and design the total configuration of the USDI (urban spatial data infrastructure)of
Ganzhou; Second we constitute the regulations of the producing and updating of spatial data, and probe in the technology of sharing
data, and we also design the framework of data sharing in the USDI of Ganzhou ,then we build up the framework dataset. Finally we
discuss the integrating of GIS and OA.
1. INTRODUCTION
USDI synthetically using the advanced communication network
technology, GIS technology, remote sensing technology,
global-positioning technology and the technology of data base
management system, integrates, shares and utilizes the space
data information of every department, trade, field in the city to
the maximum extent to offer fast, systemic and various kinds of
succinct data service, and promotes economic construction of
the city and social development. Comparing with the "national
spatial data infrastructure "being constructed in our country, the
urban spatial data infrastructure has its particularity , for
example ,the resolution ratio is high, abundant in content, the
amount of information is large, the aging speed of information
is fast, production and newer cycle are long and costly. The
efforts of recent years have obtained the remarkable
achievement in production of the data of urban space of our
country. Now we take Ganzhou as an example, carry on the
discussion to the construction of urban spatial data
infrastructure.
2. ESTABLISHING THE MECHANISM TO MANAGE
AND HARMONIZE SPATIAL DATA
The construction of urban spatial data infrastructure involves a
wide range of departments, but most cities often entrust the
urban planning or the construction department to be responsible
for while building of the system and the corresponding
powerful organizational leadership structure has not been
established. Although the leading group, a kind of loose
organization has been established in some cities, the influence
on system construction is not very big, causing the system is
unable to spread out construction or use in the large range, thus
influencing systematic using value. Aiming at this situation we
establish a space datum to coordinate the management
organization in Ganzhou, It specially undertakes the spatial data
infrastructure construction task in Ganzhou. This organization is
a production unit of the foundation geographical information
data of Ganzhou, and it is an authoritative service centre that is
charge of upgrading, storing, dealing with and assigning the
basic space data, and it is one of the components of the national
spatial data infrastructure.
This organization, according to the need of producing,
managing and servicing spatial data in Ganzhou, has designed
the ensemble architecture of Ganzhou, as Fig. 1 shows.

3. MAKING THE RULES OF URBAN BASIC
SPATIAL DATA
Urban space basic data include mainly: the digital line vector
graphic (DLG ); the digital orthograph model (DOM ); the
digital elevation model (DEM ); The digital raster graphic
(DRG ); the corresponding attribute data of various kinds of
data, including attributive character information, social
economic information, every department special use
information etc. Each kind of data involves the data form of
different scales.
In order to make the space data has effectiveness for a given
period of time, authoritativeness and sharing, we have made the
