Why we need TGOS?
It is very difficult for end-users to get complete, real time
geospatial data from various agencies.
Therefore, Information Center of Ministry of the Interior
constructed the NGIS Data Warehouse (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 data sharing and supply of NGIS.

Introduction to TGOS
In 2003, the TGOS Portal developed by the Information
Center, it is to provide the e-commerce services of processing
geospatial data supply.
Since 2007, with the apprehension of the needs for valueadded applications among various organizations, the
Information Center have been advocating the web service
concept and integrated process technology to expedite the
application and development of national geographic
information system, with the introduction of SOA (ServiceOriented Architecture) for TGOS portal function enhancement;
As well as the utilizing of enterprise Web 2.0 structure and
standardized service interface for various sources of
integrated service elements to build up the distribution of
geospatial data and the value-added applications.

Introduction to TGOS
In response to the recent expansion of system user interface,
information standards and physical operation models as
results of information technology and GIS advancement, the
Information Center revised and integrated TGOS portal in
2008.
It also drafted TWSMP 1.0 metadata standard in June 2007,
and developed web version as well as standard-alone version
of metadata editing system so as to be compliant with ISO
19139 XML schemas.
This system is to be used by geospatial data suppliers for the
purpose of upgrading efficiency of metadata editing and
importing and to establish sharing environment for NGIS
geospatial data distribution.

Conclusion
32
Present Status of Partnership Promotion
The Information Center has been assisting and
inviting the central and local governments to be the
partners at large scale since 2008;
Presently, there are 38 organizations and 526
categories of geospatial data participated
Each partner could choose its own level of
partnership, according to its system readiness and
environment development such as that for metadata
search, web publish service, application process
service, file copy service, logistics channel provider,
and payment channel provider, etc.
33
compliance of Partners
Setting up the distribution standards and
pricing policy of geospatial data that a partner
is deemed responsible and authorized.
Maintaining and updating geospatial data and
metadata that a partner is deemed responsible
and authorized to notify and upgrade TGOS
portal upon the occurrence of revision.
Registering geospatial data or service to
TGOS portal.
34
compliance of Partners
Uploading metadata file to TGOS portal.
Storing geospatial data file to TGOS portal.
Setting up the software and hardware
platforms in line with the TGOS portal, in order
to publish WMS or WFS.
Processing the operation of review, logistics
and cash flow for geospatial data distribution.
35
Problems and Difficulties for Partners
It is disappointing that so far there are quite a
few partners are unable to augment partnership
other than metadata due to incapable technical
environment for Internet WMS publish and
inadequate applicable geospatial data
distribution schemes; thus it is one of the
important tasks of future partnership promotion
and advancement.
36
Functions and Resources of
the Information Center
Functions
– Training partners for the operation of TGOS portal.
– Setting up SOP for partnership administration.
– Monitoring regular Internet services provided by
partners and requesting for fast recovery upon any
instance of defect.
– Maintaining normal operation of TGOS portal.
– Coordinating activities and promotion for
geospatial data distribution.
37
Functions and Resources of
the Information Center
Resources
– Providing technical inquiries and assistance for
partnership administration.
– Initiating the regulations for geospatial data
distribution procedures as reference.
– Setting up sales channels for geospatial data.
– developing the priority list for subsidizing the local
government’s geospatial data projects.
38
The Benefits of TGOS Portal
Setting up simultaneous establishment of
geospatial data management mechanism
within organizations.
Establishing national geospatial data sharing
mechanism and channels.
Resource-raising for maintenance of
geospatial data according to the principle that
data is of price value thus ought to be user
paid.

Current Development of TGOS
There are 38 organizations and 526
categories of geospatial data to join the
TGOS portal .
Introduce the concepts of Web Services
technology and use Service - Oriented
Architecture (SOA) to reinforce and expand
TGOS functions.
41
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, resulting in value added
applications.
42
Service-Oriented Architecture（SOA）
The utilization model of the Service-Oriented
Architecture (SOA) is based on three roles: the
Service Broker, the Service Provider, and the Service
Requester.
Service Broker
Bind
Service Requester
Service Provider
43
Future Development of TGOS
Continue the integration of spatial data and
partnership.
Expand the system functions of the TGOS
portal.
Establish the value added platform.
Promote the efficiency of the TGOS portal
operation.

Conclusion
The Achievement of the TGOS ：
– Collect spatial data from different government
agencies, provide metadata searching and
editing, map browsing and inquiring, and map
data supply.
Key success factors for the TGOS：
– Collaborate and cooperate between the center
government, the local government, industrial
circles and academic researches.
