Transcription

1 THAILAND NSDI DVELOPMENT PROGRAM: ThaiSDI Dr.Chaowalit Silapathong Director of Geo-informatics Office Geo-Informatics and Space Technology Development Agency (Public Organization): GISTDA

2 Situation of GIS in Thailand Thailand: 314,000 sq.km. land surface More than 100 agencies working on GIS One Technology, Many Stakeholders of June 2007

3 Situation of GIS in Thailand Problems: Many actors but work isolately Duplication on data production Cooperation and collaboration are limited Poor sharing of data / facilities / resources Big amount of budget but scattered and unretrievable data Data standards? Lack of expert / trained personnel Unclear policy: national policy? agency policy? Data policy?...

4 National Spatial Data Infrastructure: NSDI Institutional Framework NSDI Elements Technical Standards Fundamental Datasets Access Network/Clearinghouse To solve problems: introducing of NSDI

5 Thailand NSDI Development & Implementation Since 2002 Actors: - National Commission on GIS - Stakeholders - End users GIS Master Plan Vision Strategic Plan Identification of Key Actors / Stakeholders GISTDA-CU: Feasibility Study Functional requirements High-Level Architecture Implementation & Investment Plan GISTDA-ESRI-USTDA: NSDI Implementation Develop Best Practices Implement Standards and Policies Build Geospatial Portal Develop Data Maintenance Roadmaps National Commission: 2004

6 NSDI : expectations Elimination of redundant GIS data collection and management within Thailand Interoperability and data sharing through the establishment of data content and metadata standards Better decision-making through spatial analysis Reducing costs/budgets

7 Organization of National GIS Commission Members: Deputy Prime Minister Minister of of ICT ICT Minister of of ST ST CEOs of of relevant agencies, experts, and and representatives from from academic institutes to establish and direct GIS national policies and to promote coordination/cooperation amongst stakeholders Cabinet National GIS GIS Commission GIS GIS Coordinator (GISTDA) Subcommittees: Mapping and and Data Content Standard Usage of of 1:50,000 Series L7018 Usage of of 1:25,000 MOAC Orthophotos GPS Monument Usage Administrative Boundary Standard Working Groups for for Each Subcommittee Since 2003

21 Conclusion Initiative of NSDI of Thailand since 2003 ThaiSDI; GIS clearinghouse in 2006 Standards : ISO/TC211 and OGC Still long way to go

22 Expectation from IHLET Tiza Sharing experiences in development of SDI Solution for NSDI (best practice) Guidance on extension from national to regional level SDI for Mekhong river basin ( concerns 5 nations)
