4Why StandardsGIS data The most expensive investment foran organization Research by the US NationalCenter for Geographic Informationand Analysis 60% to 80% of the total costs Created by many differentorganizations Using many different methods andtechnologies Using many different software anddata formats
5Why StandardsFacilitate data sharing – data exchanging,reusing and integration.
6Why StandardsIncrease interoperability among automatedgeospatial information systems.Provide for consistency in interfacesbetween data, users and systems.
7Roles of Standards Organizations ISO provides a framework for the developmentof specific standards, and has set up a TechnicalCommittee on Geographic Information/Geomatics(ISO/TC211). Industry Consortia provide technicalimplementation specifications.The Open Geospatial Consortium (OGC) Regional and national groups adoptinternational standards and standardize dataand services using international standards.Chinese National Standard (CNS)

9Strategy for the Development ofNGIS StandardsStandards Working GroupEstablish standards with consensus fromCentral, local governments, academic,and private sector.The NGIS Standards Process is1.Structured2.Iterative3.Well-documented
10NGIS Standards ProcessThe NGIS standards development processis modeled after ISO and CNS standardsprocesses.Developed by a four step processStage 1: Proposal StageStage 2: Draft StageStage 3: Review StageStage 4: Publication Stage

NGIS Standards Accomplishments 22 data standards have beenapproved. All data standards could bedownloaded from the “NationalGeographic InformationSystem Standards” website. http://standads.moi.gov.tw/12

Data Standards_(4/4)16Enviromental Quality Data Standard － soil pollution and wastePipeline Data StandardEnviromental Quality Data Standard － pollution control,environmental sanitation, noise and vibration, and non-ionizedradiation
17Current and Future DevelopmentApply ISO standardsISO/TC211 began to publish GIS standards from 2002.Reviewing and revising NGIS standards.The NGIS standards will be a set of national profiles ofthe ISO standards.Developing framework data standardsis the top priority, then other thematicdata 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)
19Positive ImpactThe private sector (software developersand vendors) will benefit by developingtools that exploit data based on these datacontent standards.Data producers and customers will benefitfrom improved access to data throughcommon data content standards.
20ConclusionStandards facilitate data sharing andincrease interoperability.Focus on important standards todevelop.
