Efforts in Thailand

A Study of Government Data Infrastructure 2001-2002

Initiated by the National Information Technology Committee (NITC), Ministry of Science and Technology

study of data integrity in Thai government

4 Categories of Data: personal data,…. spatial data

For spatial data, study done by Chulalongkorn University

Final report is underway.

Outcomes of GDI

Overview of european and north-american standard

Analysis of NSDI throughout the world

Overview of Thai administration

Seminars and Interview 200 departments and at 5 Ministry CIOs

Prototype Clearinghouse: Isite with gateway implementation

Web Map Server Interface Standard: Minnesota MapServer

Prototyte: Clearinghouse

Base on FGDC: Isite package

Gateway also has been realized.

Conclusion

Open Source Software has open way for researcher to enable ‘standard’.

Thailand has ‘learnt by doing’ using OSS

Research and education for standardized GIS is going on.

Once technology is possessed and requirement had been ratified, then

‘Standards are in Action!!!’
