ISO Technical Committee (TC) 211 on Geographic Information

Point of contact: Agneta Gren Engberg, ISO/TC 211 chair, agneta.gren.engberg@lm.se

A business view on the standardization of Geographic Information should ideally be a description of the evolving use of geodata in still new environments. As we know the evolving technology will set new standards (level of applications) for the need of integration and hence the interoperability of geodata with themselves and with other types or domains of data.

 

The consequences in any circumstances will be the need for more standards with geodata in one corner, or even the centre, of the application.

This corner could be embedded geodata or new type of derived geodata, maybe target towards some specific applications. Either way, the standardization results that already are achieved will only create new needs for interoperability and new kinds of geodata .

                            ISO/TC 211 business plan

 

The scope of ISO/TC 211 is very wide, but the work currently concentrates on a few segments;

  • modelling and documentation of geographic information, traditionally important for major actors like the public sector,
  • spatial data infrastructures (SDIs) with emphasis on sharing and dissemination of geographic information through services,
  • embedding of geographic information in everyday life – ubiquitous geographic information,
  • some specific domains where geographic information is an important component and where multiple disciplines are involved.
  • The primary focus of ISO/TC 211 is geographic information and geomatics as an enabling technology within Information and communications technology (ICT).

 

 

The vertical integration of geomatics standard with ICT in general implies a specific focus on eGovernment and semantic web. During the last meeting in Slovenia in June 2019 ISO/TC 211 decided to establish a category C liaison between W3C (the World Wide Web Consortium) and WG4 of ISO/TC 211. A closer relationship with W3C may ease the take up of spatial data in the eGovernment infrastructure, and influence the further work on location enablement and location intelligence.

Another issue is the horizontal integration. A joint working group with ISO/TC 59 SC 13 for the interoperability between GIS (Geospatial) and BIM (Building Information models) has been working for a year now, a technical report on interoperability barriers and possible measures is planned to be submitted in October 2019, as a fundament for further actions in the Joint working group or in the respective committees,

A joint working group with ISO/TC 204, ensuring interoperability between GIS and the ITS domain has just been established, under the responsibility of ISO/TC 211.

The business plan and the working group structure according to the program of work will be under evaluation, to ensure that we have the appropriate organization for providing the necessary standards for the future. A close cooperation with OGC is essential to ISO/TC 211.

 

The geodetic registry is now up and running, see https://registry.isotc211.org . The ISO Geodetic Registry is a structured database of coordinate reference systems and transformations that is accessible through this on-line registry system, maintained by a control body of geodetic experts. The Register includes only systems and transformations of international application. It does not include all possible coordinate reference systems and transformations.


 

Several of the ISO/TC 211 standards are now revised and available as the second generation of standards.  The table below shows standards referenced in the INSPIRE implementing rules, the next table shows the revision history of these standards.

ISO 19131 Data product specification, which is the basis for the INSPIRE data specifications,  is under revision, expected to be published in 2020

Resources from ISO 191xx standards are now available at https://www.isotc211.org/ . All XML schemas, html views of the UML models and ontologies are available here or in further references to GitHub. In addition, ISO/TC 211’s multilingual glossary for geographic information technology is available as geoloxica. Still under development.

The ongoing work on WFS 3,0 in close cooperation with OGC is planned to be submitted as DIS (Draft international standard) in July 2019. The title in ISO will be ISO 19168-1 "Geographic Information - Geospatial API for Features - Part 1: Core".

 

ISO/TC 211 acknowledge that JRC will no longer maintain the harmonized model repository and necessary actions will be taken.

Technology Trends watch - Highlighted topics – near term actions

Change in the technology industry is constant. The OGC Technology Trends process ( http://www.opengeospatial.org/OGCTechTrends ) looks at a wide variety of sources for trends information including: industry reports, international research, OGC members, alliance partners and staff.

Why does OGC track geo technology trends?

OGC’s position on Innovation (2014): “develop standards to support evolving and potentially disruptive technologies, community needs and market trends.“ The Technology Trends Watch is a formal technology strategy, lead by the OGC CTO, to track and promote technology evolution.

Meta Trend

Data Science and Analytics

Description
from Wikipedia

Subfield of computer science that gives computers the ability to learn without being explicitly programmed. Deep learning - a sub type of machine learning - consists of multiple hidden layers in an artificial neural network.

What is new or emerging?

          3 rd generation of Machine Learning providing revolutionary big data capabilities

          Need for robust training sets and methods to efficiently develop them

Why might it matter?

          Significantly improved ability to to identify features in geospatial datasets, e.g., patterns in linked data, objects in features.

  • The Dataset Exchange Working Group [2] updated the Data catalog Vocabulary version 2 on 28 May 2019, the DCAT Profiles Vocabulary on 2 April 2019, and the Content Negotiation by Profile on 30 April 2019.
  • The Spatial Data on the Web Interest Group [3] is discussing maintenance and update of the vocabularies and Spatial Data on the Web Best Practices document that were published last year. In addition, the group is also identifying areas where standards should be developed jointly by both W3C and OGC, using the overall W3C Strategy Funnel [4] , which triages topics into the following stages: Exploration, Investigation, Incubation, Evaluation and Standardization (this last step is out-of-scope for the Interest Group). It has also started to work on best practices for Statistical Data (no document published yet).
  • The Linked Building Data Community Group [5] brings experts together on building information modelling (BIM) and Web of Data technologies to define existing and future use cases and requirements for linked data applications.
  • W3C has chartered a Working Group on updating the popular JSON-LD specification [6] .
  • The Web of Things Working Group [7] is progressing work on standards for exposing physical and abstract entities (things) as objects with properties, actions and events, independently of the communication protocols. The approach uses Linked Data with URIs for naming things and linking to their descriptions, and provides the basis for semantic interoperability across open markets of services. We expect the specifications to reach W3C Recommendation status in mid-2019 following the publication of Candidate Recommendations for Web of Things Architecture and Thing Descriptions on 16 May 2019. The Second W3C Workshop on the Web of Things [8] took place in Munich on 3-5 June 2019.
  • A W3C standardisation workshop [9] took place in Berlin on 4-6 March 2019 on bridging communities (RDBMS, Property Graphs, RDF/Linked Data, AI/ML) on identifying opportunities for further standardisation work, e.g. extending RDF to embrace Property Graphs, alignment on graph data query languages, and context sensitive mappings between vocabularies with overlapping semantics. A follow on workshop on time-series and spatial data is now at an early stage of planning. A Graph Standardisation Business Group is in the process of being launched to coordinate technical standards work and liaisons with standards development organisations and industry alliances.
  • A W3C study of Web data standardisation [10] has been produced with support from the Open Data Institute and InnovateUK, with a view to   making W3C a more effective, more welcoming and sustainable venue for communities seeking to develop   Web data standards and exploit them to create value added services.
