The Development of NGIS Standards
NGIS Standards Accomplishments
Current and Future Development
Conclusion

4. 4
Why Standards
GIS data
 The most expensive investment for
an organization
 Research by the US National
Center for Geographic Information
and Analysis
 60% to 80% of the total costs
 Created by many different
organizations
 Using many different methods and
technologies
 Using many different software and
data formats

5. 5
Why Standards
Facilitate data sharing – data exchanging,
reusing and integration.

6. 6
Why Standards
Increase interoperability among automated
geospatial information systems.
Provide for consistency in interfaces
between data, users and systems.

7. 7
Roles of Standards Organizations
 ISO provides a framework for the development
of specific standards, and has set up a Technical
Committee on Geographic Information/Geomatics
(ISO/TC211).
 Industry Consortia provide technical
implementation specifications.
The Open Geospatial Consortium (OGC)
 Regional and national groups adopt
international standards and standardize data
and services using international standards.
Chinese National Standard (CNS)

Strategy for the Development of
NGIS Standards
Standards Working Group
Establish standards with consensus from
Central, local governments, academic,
and private sector.
The NGIS Standards Process is
1.Structured
2.Iterative
3.Well-documented

10. 10
NGIS Standards Process
The NGIS standards development process
is modeled after ISO and CNS standards
processes.
Developed by a four step process
Stage 1: Proposal Stage
Stage 2: Draft Stage
Stage 3: Review Stage
Stage 4: Publication Stage

11. 11
NGIS Standards Process
STAGE STEP CUSTODIAN
PROPOSAL 1- Develop Proposal Any organization
2- Review Proposal Standards Working
Group (SWG)
3- Set Up Project Development
working group
DRAFT 4- Produce Working Draft Development
working group
REVIEW 5- Review and Evaluate SWG
6- Public Review & Respond SWG & Development
work group
7- Approve Standard for
Endorsement
SWG
PUBLICATION 8- Endorsement NGIS Steering
Committee

12. NGIS Standards Accomplishments
 22 data standards have been
approved.
 All data standards could be
downloaded from the “National
Geographic Information
System Standards” website.

13. Data Standards_(1/4)
13
Data Standard Specification
Metadata Standard (TaiWan Spatial Metadata Profile, TWSMP)
Administrative Boundaries Data Standard
Control Points Data Standard
Elevation Data Standard
Address Data Standard

14. Data Standards_(2/4)
14
Place Names Data Standard
Transportation Networks Data Standard
Hydrography Data Standard
Cadastre Data Standard
Digital Orthoimagery Data Standard
Basic Geology Data Standard

15. Data Standards_(3/4)
15
Landuse Data Standard
Pipeline Data Standard Specification
Land Use Zoning Data Standard
Botany Data Standard
Enviromental Quality Data Standard － air quality and water
quality
Road Networks Data Standard

16. Data Standards_(4/4)
16
Enviromental Quality Data Standard － soil pollution and waste
Pipeline Data Standard
Enviromental Quality Data Standard － pollution control,
environmental sanitation, noise and vibration, and non-ionized
radiation

17. 17
Current and Future Development
Apply ISO standards
ISO/TC211 began to publish GIS standards from 2002.
Reviewing and revising NGIS standards.
The NGIS standards will be a set of national profiles of
the ISO standards.
Developing framework data standards
is the top priority, then other thematic
data standard.
Developing web services standards

18. Web Map Tile Service (WMTS)
 Serving nation-wide reference map for Web-based application.
 A common specification for establishing web map tile service.
 Two reference system
 EPSG 3857 (compatible with Google Map)
 EPSG 3826 (Taiwan local reference system)

19. 19
Positive Impact
The private sector (software developers
and vendors) will benefit by developing
tools that exploit data based on these data
content standards.
Data producers and customers will benefit
from improved access to data through
common data content standards.

20. 20
Conclusion
Standards facilitate data sharing and
increase interoperability.
Focus on important standards to
develop.
