1 Data Sharing Background in China
Data Sharing Network of Earth System Science
Scientific Data Sharing Program (SDSP) in China• SDSP was launched by MOST
in the beginning of 2002• According to its plan, there will
be 40 national data centers, cover 300 master databases, in 6 fields at the end of 2020.

DSNESS• One of 9 Pilot Projects in SDSP• Long term project, 2002-• Host by Institute of Geographic Sciences and
Natural Resources Research, CAS• Lead Scientist: Prof. Sun Jiulin, IGSNRR• http://www.geodata.cn
Data Sharing Network of Earth System Science
National Science & Technology Infrastructure (NSTI)• NSTI was launched in 2004, 2 years later after
SDSP, supported by MOST, State Development and Reform Commission, Ministry of Education, Ministry of Finance of China
• Data sharing is the core of NSTISDSP is one of important parts in NSTIDSNESS also is one of projects in NSTI

Data Sharing Network of Earth System Science
(1) Objectives• To integrate and share distributed scientific data
in Institutes, Universities, Individuals, Government funded research projects, and International organization or data centers
• Enhance and support the Earth System Science Research and Science and Technology innovation
• At present, mainly focus on “Land surface and human-land relationship” research Area

(4) Services• DSNESS provides two kinds of service, i.e.
online service and offline service. offline service is provided if data can not be accessed openly or if user asks for specific service.
• DSNESS provides data on a nondiscriminatory basis and without restriction
• Online data service is free of charge and offline data service charges no more than the cost of reproduction.
