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

Why Standards

Facilitate data sharing – data exchanging,

reusing and integration.

6

Why Standards

Increase interoperability among automated

geospatial information systems.

Provide for consistency in interfaces

between data, users and systems.

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

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

NGIS Standards Process

STAGE STEP CUSTODIAN

PROPOSAL 1- Develop Proposal Any organization

2- Review Proposal Standards Working

Group (SWG)

3- Set Up Project Development

NGIS Standards Accomplishments

22 data standards have been

approved.

All data standards could be

downloaded from the “National

Geographic Information

System Standards” website.

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

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

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

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

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

Conclusion

Standards facilitate data sharing and

increase interoperability.

Focus on important standards to

develop.
