1 Data Sharing Background in China


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.

Framework of China SDSP


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


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 portal: www.escience.gov.cn


2 DSNESS and its main resources about LCLUC


(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

Data Sharing


(3) ResourcesData Catalogue• Ecosystem background data• Social & economic development data• Coastal and delta resources and environment data• Frozen earth data• arctic pole and south pole scientific explore data• Typical regional thematic data (e.g. qinghai-tibet, loess

plateau, blackland, etc.)• Earth observation system data and data production• Solar-earth environment data


(3) ResourcesProducts from Land Use to Land Cover • Land use dataset for China of 1980s, 1990s, 2000• Land cover dataset for China of year 2005• Multi sources Remote Sensed data and dataset

productions• Land surface basic feature datasets (soil, vegetation,

lake, glacier, desert, etc.)• Typical regional thematic datasets• …

(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.

3 MAIRS and DSNESS


(1) Cooperation Basis

Research Direction

DSNESS

Cooperation Research Platform Data Sharing Platform


(2) Thematic Databases on Line• Data

requirements and categories designed by MAIRS

• Data supported by DSNESS

• Web Platform Developed by DSNESS


(3) Near futureFor MAIRS • Promote LCLUC datasets sharing• Focus on regional data center and research centerFor DSNESS• National Scientific Data Sharing Basis Funded by MOST

of China• Engage in building the cooperation research environment

(e-Science) and promoting international data sharing• Have the capacity and be interested in LCLUC datasets

cooperation and sharing in SEA
