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

4
Why Standards

• Facilitate data sharing data exchanging,
  reusing and integration

5
Why Standards

• Increase interoperability among automated
  geospatial information systems.
• Provide for consistency in interfaces between
  data, users and systems.

6
Roles of Standards Organizations

• ISO provides a framework for the development of
  specific standards. ISO has set up a Technical
  Committee on Geographic Information/Geomatics
  (ISO/TC211)
• Industry Consortia provide technical
  implementation specifications
• OpenGIS Consortium
• Regional and national groups adopt international
  standards and standardize data and services using
  international standards
• Chinese National Standard (CNS)

7
Strategy for the Development of NGIS Standards

• Standard Working Group
• Establish standards with consensus from
  Central, local governments, academic, and private
  sector
• The NGIS Standards Process is
• Structured
• Iterative
• Well-documented

8
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

NGIS Standards Accomplishments

• The NGIS Terminology
• The NGIS Metadata Standard
• The NGIS Classification Standard
• Standard Exchange Format (SEF) for Cartography
• Thematic Data Standards
• Transportation Network Data Standard
• Cadastre Database Standard
• The Basic Topographic Map Database Standard
• Regional and Urban Plan Database Standard
• Public Facility Pipeline Database Standard
• Engineering Geology Exploration Database Standard
• Hydrography Data Standard

11
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

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

14
Conclusion

• Standards facilitate data sharing and increase
  interoperability.
• Focus on critical standards.
