  1. Liaison Report from ISO TC211 to CEOS WGISSPresented at WGISS 47 Dr. Liping Di ISO/TC 211 liaison to CEOS WGISS CEOS WGISS liaison to ISO/TC 211 Center for Spatial Information Science and Systems (CSISS) George Mason University ldi@gmu.edu

  2. Contents • ISO TC 211 Organization; • ISO TC 211 Metadata standards and projects • ISO TC 211 Imagery and gridded data standards and projects.

  3. ISO TC 211 • ISO stands for International Organization for Standardization. • ISO Technical Committee 211 (TC 211) is responsible for setting international standards on geographic information • ISO has published 79 standards (including update) and 21 standards are under development • Currently TC 211 has 39 participating member countries and 21 observing member countries • ISO TC 211 has set up liaison relationship with many related external organizations, including CEOS WGISS • CEOS WGISS is a class-A liaison of ISO TC 211 • ISO TC 211 appointed as its liaison to CEOS WGISS • Currently, Dr. Liping Di as ISO TC 211 liaison to CEOS WGISS and also CEOS WGISS liaison to ISO TC 211

  4. Scope of ISO TC 211 • Standardization in the field of digital geographic information. • TC 211 aims to establish a structured set of standards for information concerning objects or phenomena that are directly or indirectly associated with a location relative to the Earth. • These standards may specify, for geographic information, methods, tools and services for data management (including definition and description), acquiring, processing, analyzing, accessing, presenting and transferring such data in digital/electronic form between different users, systems and locations. • The work of TC 211 shall link to appropriate standards for information technology and data where possible, and provide a framework for the development of sector-specific applications using geographic data.

  5. Current Working Groups in ISO TC 211 • Working group 4 Geospatial services • Working group 6 Imagery • Working group 7 Information communities • Working group 9 Information management • Working group 10 Ubiquitous public access

  6. ISO Metadata Standards • The old version of metadata standards has been deprecated • ISO 19115:2003- geographic information-metadata • Published in 2003 • The base standard for geospatial metadata • Developed from FGDC metadata standard • ISO 19115-2:2009 - Metadata - Part 2: Extensions for imagery and gridded data • Published in 2009 • Provided Additional metadata element and structure for remote sensing imagery and derived grid products • Based on FGDC remote sensing metadata standard • New version of metadata standards have been published • ISO 19115-1:2014 • ISO 19115-2:2019 • ISO 19115-3:2016 • ISO 19157:2013 • ISO 19157-2:2016

  7. ISO 19115-1:2014 and ISO 19115-3:2016 • ISO 19115-1:2014 – Geographic Information-Metadata-Part 1: Fundamentals • Published in 2014 • A revision of ISO 19115:2003 with much improvement in many areas, especially in the description of contents in multi-dimensional data • Data quality part has been moved to ISO 19157 • A replacement of ISO 19115:2003 • No direct back compatibility with ISO 19115:2003 but can be mapped from ISO 19115:2003 to ISO 19115-1:2014 • ISO 19115-3:2016 is the XML implementation schema of ISO 19115-1:2014

  8. ISO 19115-2:2019 • Geographic information -- Metadata -- Part 2: Extensions for acquisition and processing • Replace ISO 19115-2:2009 • Change the name to reflect the metadata defined in the standard are not only applicable to remote sensing

  9. ISO 19157:2013- Data quality • ISO 19157:2013 – Geographic Information – Data Quality • Combined all data quality related metadata standards in ISO TC 211 • ISO 19113 --quality principles • ISO 19114 –quality evaluation procedures • ISO 19138 –data quality measures • The quality description part of ISO 19115 • The content includes • defines components for describing data quality; • specifies components and content structure of a register for data quality measures; • describes general procedures for evaluating the quality of geographic data; • establishes principles for reporting data quality. • ISO 19157-2:2016 Geographic information -- Data quality -- Part 2: XML schema implementation

  10. Published Remote Sensing Imagery Standards • ISO 19101-2:2018 Reference model -- Part 2: Imagery • ISO 19123-2:2018 Schema for coverage geometry and functions -- Part 2: Coverage implementation schema • ISO/TS 19129:2009 Imagery, gridded and coverage data framework • ISO/TS 19130-1:2018 Imagery sensor models for geopositioning -- Part 1: Fundamentals • ISO/TS 19130-2:2014 Imagery sensor models for geopositioning -- Part 2: SAR, InSAR, Lidar and sonar • ISO/TS 19159-1:2014 Calibration and validation of remote sensing imagery sensors and data -- Part 1: Optical sensors • ISO/TS 19159-2:2016 Calibration and validation of remote sensing imagery sensors and data -- Part 2: Lidar • ISO/TS 19159-3:2019 Calibration and validation of remote sensing imagery sensors and data -- Part 3: SAR/InSAR • ISO/TS 19163-1:2016 Content components and encoding rules for imagery and gridded data -- Part 1: Content model • ISO 19165-1:2018  Preservation of digital data and metadata -- Part 1: Fundamentals

  11. On-going projects that WGISS can contribute to • ISO 19123-1 Coverage – Part 1: Fundamentals • A revision of ISO/TS 19123:2005 Schema for coverage geometry and functions • ISO 19130-3 Geographic information – Imagery sensor models for geopositioning - Part 3: XML schema implementation • Currently at WD stage, advancing to DTS • ISO 19150-4 Geographic information - Ontology, Part 4: Service ontology • Project at DIS stage • ISO /TS 19163-2 Content components and encoding rules for imagery and gridded data -- Part 2: Implementation schema • ISO 19165-2 Preservation of digital data and metadata -- Part 2: Content specifications for earth observation data and derived digital products • Currently at DIS stage

  12. Standard projects being proposed • ISO 19159-4 Calibration and validation of remote sensing imagery sensors and data -- Part 4: Passive Microwave Sensors • Proposed by China • ISO XXX Calibration and validation of remote sensing data and derived products – multiple parts • Part 1: Fundamentals • Part 2: Data from Optical sensors • Part 3: Data from Hyperspectral sensors • Part 4: Data from Lidar • Part 5: Data from SAR/InSAR • Part 6: Data from Microwave • Part 7: Thematic products • Part 8: Cal/Val sites

  13. ISO TC 211 Meetings • ISO TC 211 holds its plenary and working group meeting twice per year (one in May/June and another in November/December) • The 47th plenary was hold in Wuhan, China in November 2018 • The 48th plenary will be held in Maribor, Slovenia in the first week of June 2019 • CEOS WGISS can contribute significantly to ISO standard development, especially in remote sensing and data systems • Need WGISS input for the liaison report to the 48th plenary.
