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 in data construction and
archives.
– Facilitate sharing and supply of NGIS data.

6
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.
7
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.
8
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）
9
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）
10
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）
11
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
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.

Conclusion
15
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.
16
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 valueadded applications.
17
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.
Service Broker
Bind
Service Requester
Service Provider

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.
20
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.
