  3. Why we need TGOS? • It was very difficult for end-users to get complete, real time spatial data from various agencies. • Therefore, Information Center of Ministry of the Interior constructed the NGIS Data Warehouse and Clearinghouse (also called Taiwan Geospatial One-Stop Portal, or TGOS) in order to: • Integrate spatial data from different organizations. • Reduce redundancy indataconstruction and archives. • Facilitate sharing and supply of NGIS data.

  6. Introduction to TGOS Evolution of TGOS TGOS Promotion Strategy Future Development of TGOS Conclusion Presentation Overview

  7. Evolution of TGOS • Stage 1 (prior to 2000) • Developing the “NGIS Clearinghouse” as the inquiry and service portal for NGIS data. • Encouraging relevant government authorities to draft related services regulations for data distribution.

  8. Evolution of TGOS • Stage 2 (from 2001 to 2003) • Establishing NGIS metadata query system and NGIS service portal. • Integrating the NGIS databases developed by government agencies. • Speeding up the supply services of NGIS data.

  9. Evolution of TGOS • Stage 3 (from 2004 to 2008) - 2004 • Establishing the integrated system of TGOS. • Choosing three ambitious government agencies as the model of data warehouse supply nodes, building up an interface system for online map services. • Cost Budget：NT＄2.5million（US＄75,000）

  10. Evolution of TGOS • Stage 3 (from 2004 to 2008) -2005 • Integrating maps and attribute data for alliance nodes. • Picking up nine related agencies both in center government and local government as target alliance nodes for providing assistance. • Constructing financial and data logistics system for online payment and digital data download. • Cost Budget ：NT＄4.6million（US＄139,000）

  11. Evolution of TGOS • Stage 3(from 2004 to 2008) - 2006 to 2007 • Planning to apply the Service-Oriented Architecture (SOA) in TGOS. • Analyzing and setting up a pilot system for map supply and application platform in line with the needs of the land monitoring, land planning, land restoration, disaster prevention and rescue, and other major national infrastructure projects. • Cost Budget ：NT＄7.7million（US＄233,000）

  12. Evolution of TGOS • Stage 3 (from 2004 to 2008) - 2008 • Speeding up the promotion of TGOS alliance nodes, and address the issue of sustainable operations, reinforce the value-added applications of geospatial mapping. • Improving the data and process services of a SOA after 2008.

  13. Introduction to TGOS Evolution of TGOS TGOS Promotion Strategy Future Development of TGOS Conclusion Presentation Overview

  14. TGOS Promotion Strategy • Using new IT technology to achieve the aggressive goal of data warehousing. • Speeding up the integrated utilization of the existing database. • Drafting NGIS data standard, in order to faster data supply services.

  15. Introduction to TGOS Evolution of TGOS TGOS Promotion Strategy Future Development of TGOS Conclusion Presentation Overview

  16. Future Development of TGOS • Consider the need for value added applications. • Introduce the concepts of Web Services technology and use Service - Oriented Architecture (SOA) to reinforce and expand TGOS functions.

  17. Service-Oriented Architecture（SOA） • Service-Oriented Architecture (SOA)is a collection of services that communicate with each other while supporting the needs of software users. The services have a platform-independent interface so the service may be used on any OS and in any language. • Service-Oriented Architecture (SOA) solve the compatibility problem of information system, allow user to save large amounts of construction and maintenance costs, which will be helpful in value- added applications.

  18. Service Broker Publish Find Bind Service Requester Service Provider Service-Oriented Architecture（SOA） • The utilization model of the Service-Oriented Architecture (SOA) is based on three major services: the Service Broker, the Service Provider, and the Service Requester.

  19. Introduction to TGOS Evolution of TGOS TGOS Promotion Strategy Future Development of TGOS Conclusion Presentation Overview

  20. Conclusion • The Achievement of the TGOS ： • Collecting spatial data from 6 government agencies with 52 map data, 817 metadata data sets （it’s more than 10 thousand records）; having 13 alliance nodes offering online purchase, map data supply and other service; enhancing resource sharing and valued-added application. • Key success factors for the TGOS： • Collaborate and cooperate between center government, local government, industrial circles and academic research community.

  21. Conclusion • Development and Prospect of the TGOS ： • To increase alliance nodes for integrating more spatial data, • To establish the value-added service platform, • To provide more system services, and • To promote operation effectiveness of the TGOS.
