2 Contents  Open Source Software  Efforts at Chulalongkorn University  Conclusion and Outlook

3 Open Source Software

4 Benefits of Open Source Software  Cut down budget  Opportunity for technology exploration  On-the-job training and education  Prototyping and demo  Excellent tools for research and development

5 Interesting Web Sites  www.fgdc.gov : isite www.fgdc.gov  www.freegis.org : 158 entries www.freegis.org  UMN/DNR MapServer : mapserver.gis.umn.edu  Postgis http://postgis.refractions.net/  OGDI (Open Geographic Datastore Interface)  GeoServer: geoserver.sourceforge.net  Others: proj4, gml4j, gdal

6 Interesting Projects  Minnesota MapServer  Package of cgi-based map server  Known of standard GIS data format  Developed by UMN, DNR Minnesota  WMS 1.0.X compliant.  PostGIS  OpenGIS SF specification  Using Postgres as DB Engine  Some advance indexing features

7 Efforts in Thailand

8 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.

9 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

10 Prototyte: Clearinghouse  Base on FGDC: Isite package  Gateway also has been realized.  Two experimental node

25 Upcoming Events  Open source GIS and GRASS users conference 2002, Trento, Italy, 11-13 September 2002, University of Trento http://www.ing.unitn.it/~grass http://www.ing.unitn.it/~grass  PNC Annual Conference and Joint Meetings 2002 PNC/ECAI/ IPSJ-SIGCH/EBTI, 15 th -23th September, Japan, http://pnc-ecai.oiu.ac.jp/index-e.html  International Symposium on GeoInformatics for Spatial Infrastructure Development in Earth and Allied Sciences, GISIDEAS'2002) Hanoi, Vietnam, 25-28 September 2002, http://gisws.media.osaka-cu.ac.jp/gisideas/ http://gisws.media.osaka-cu.ac.jp/gisideas/  “ Digital Asia ” Project, under the Digital Asia Network (DAN) initiated by ACRORS/AIT, promoting on OpenGIS for spatial information sharing, 2002-2005, http://www.acrors.ait.ac.th/digital_asia/  Training Program on OpenGIS for Spatial Information Sharing held by GAC, during 12 th -16 th November 2002, Bangkok, http://www.gac.ait.ac.th/training/schedule.htm

26 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

27 ‘ Standards are in Action!!! ’
