KEY WORDS: Land and Resources, Information Sharing, Platform 
ABSTRACT: 
With the development of land and resources informatization, huge amounts of information resources has accumulated, but data 
between different departments is hard to share and utilize, the unitary effect can not be realized. To improve the ability of decision 
making for the management of Land and resources and to satisfy a variety of requirement of information of land and resources from 
different departments and the public, it is urgent to build a information sharing platform of land and resources based on the network. 
This paper introduces the architecture, the main content and the evolution and prospect of the project of the information sharing 
platform of Land and Resources. 
1. INTRODUCTION 
Information of Land and Resources includes Land information, 
geology and mineral resources information, Ocean information 
and Survey and mapping information, which are distributed in 
different institutions and organizations. Increasing numbers of 
Information of Land and Resources has accumulated with the 
development of land and resources informatization in recent 
years, but due to organizational and technological barriers, data 
between different departments is hard to share and utilize, the 
unitary effect can not be realized. 
Information sharing of Land and Resources need to be better 
addressed to Land and Resources management, relevant 
industry and public users. Decisions making of the government 
usually involve a vast range of sectoral institutions and 
organizations at various administrative levels with different 
systems and services. Relevant industry and public also need 
getting information of Land and Resources to combine analysis 
with their own data and to avoid repeated producing data. 
Unfortunately, exchange of relevant information needed for 
Information of Land and Resources is often limited to a raw 
data exchange level and true efficiency, in most cases, is 
hindered by administrative and legal boundaries as well as a 
lack of interoperability on the technical side. 
In an attempt to solve some of these problems, the Information 
centre of Ministry of Land and Resources P.R.C has made 
“Integration and sharing platform of Information of Land and 
Resources” one of its strategic objectives of the Digital Land 
project. The information sharing platform project is the projects 
that recently started in this area. The main goal of project is to 
design and implement an open service oriented software 
architecture and to provide some data sharing services that will 
improve the information sharing of Land and Resources. 
In order to realize this goal, the key objectives for the project 
are the following: 
• To design an open service-oriented architecture for 
distributed data sharing of information of Land and 
Resources 
• Data sharing services. In this context the project will 
provide five data sharing services, including metadata 
catalogue service, metadata catalogue service system, 
spatial data sharing service system based on gridmap 
technology, spatial data sharing service system based on 
WebGIS technology, non-spatial data sharing service 
system and data apply and approve service system, the 
five data sharing services get together to satisfy various 
users requirement of information of Land and Resources. 
• To develop Data planning and data processing, this works 
out the plan of the data sharing services and prepares the 
data needed for the data sharing services. 
• Information sharing management specification and 
operational mechanism, which sets up the management 
mechanism and standards to standardization the 
construction and the operation of the platform. 
• Setting up Software and hardware environment, which 
provides the software and hardware required by the 
information sharing platform of land and resources. 
The project started in 2006. Currently the focus of the work is 
on understanding user needs, data planning and standardization, 
system requirements, an assessment of useful technologies and 
developing data sharing services system for spatial data. One of 
the designed five data sharing systems has been successfully 
developed and widely used in the intranet of Ministry of Land 
and Resources P.R.C. In the following we will first explain the 
architecture, the data sharing services and the key technology of 
the project. 
2. ARCHITECTURE AND MAIN CONTENT 
The information sharing platform of land and resources has one 
information service centre and four professional data 
management centre: Land data management centre, Geology 
and mineral resources data management centre, Ocean data 
management centre and Survey and mapping data management 
centre. See figure 1.
