SDI from a technological perspective: Standards Arnold Bregt
Technology People Policies Spatial Data Standards Components
Contents • Why Standards? • Classification of standards • Standardization organizations • Standards for SDI
Standards • Can you mention a few standards in daily life?
Why Standards? • Efficiency • Rules and threshold for society • Increase connectivity
Classification of standards • Ad hoc standards • Proprietary standards • De facto standards • De jure standards
Organisations ISO/tc211 OGC EU (INSPIRE) CEN/tc278 National government NEN
Standardization organizations • ISO • OGC • CEN
ISO • Founded 1926 • Non-governmental organization • 1994 ISO TC 211 Geographic information/geomatics • http://www.isotc211.org/
Exercise 1 • 1) What is the name and number of the last ISO19XXX series? • 2) When was the first plenary of the ISI TC 211? • 3) What is the prize of ISO 19115-1:2014 Standard
Organization - process • ISO • Technical committee (TC) for particular domain • Working group (WG) for particular group of standards • Project team (PT) for particular standard • Stages • Proposal (NWIP = New Work Item Proposal) -> TC • Preparatory stage (WD = working draft) -> WG • Committee stage (CD = committee draft) -> TC • Enquiry stage (FDIS = (final) draft international standard) • Approval stage -> TC & all ISO member bodies: final Yes/No • Publication stage (IS = international standard)
OGC • Open Geospatial consortium • Founded 1994 • Industry consortium • Implementation specifications • For instance: WMS, WFS, GML, • http://www.opengeospatial.org/ • Testing of implemenations
Exercise • 1) What are the 5 most implemented OGC specifications? • 2) How many software products support OGC specifications/standards? • 3) What are OGC standards to be used for Smart Cities?
CEN (now dormant 2015) • CEN organization 1961 • TC 287 (Geographic information) • Founded 1991 • Revival in 2004 • Adoption of ISO standards • CEN TC 287
Standards for SDI (basis) • Meta-data • Spatial data reference models • Services
Metadata • ISO 19115 (formal description) • ISO 19139 (technical implementation) • Catalog service (CAT) • Metadata about services (ISO 19119 )
Spatial data reference models • ISO 19101 (reference model) • ISO 19107 (Spatial schema) • ISO 19108 (Temporal schema) • ISO 19109 (Application schema) • ISO 19111 (Spatial referencing by coordinates) • ISO 19112 (Spatial referencing by geographic identifiers)
Services • Web map service (WMS) • Web feature service (WFS) • Web coverage service (WCS)
Combining Services Mapping service Sensor service Image service Geo spatial service Source
INSPIRE- Implementing Rules (IR) • IR for the creation and updating of metadata • IR for monitoring and reporting • IR for discovery and view services • IR for download services • IR for coordinates transformation service • IR governing the access rights of use to spatial data sets and services for Community institutions and bodies • IRs for the interoperability and harmonization of spatial data sets and services for Annex I spatial data themes
INSPIRE • Inspire Information • Inspire Video
Summary • There are a lot of GI standards • Produced by ISO, OGC and CEN (Europe) • Implemented in a variety of software implementations • Large part of it is used and relevant for SDI
