FIG Commission 5 - Positioning and Measurement  

Work Plan 2023-2026

PDF: Origional work plan in .pdf format
VIDEO: Chair of the commission Ryan Keenan takes you through the work plan

Terms of Reference

  • The science of measurement (instrumentation, methodology and guidelines)
  • The acquisition of accurate and reliable survey data related to the position, size and shape of natural and artificial features of the Earth and its environment and including variation with time consistent with internationally adopted standards and models.

Mission Statement

Positioning and Measurement is at the core of the surveyor’s profession and underpins FIG Council’s Vision over the term 2023-2026: ‘Serving society, benefitting people and the planet’ and so enabling us to tackle the Global Challenges.

To support this vision, the mission of Commission 5 is to:

  • Focus on modern technologies, and technical developments and assist individual surveyors, engineers and GIS/LIS professionals through guidelines and recommendations, to choose and utilise those methods, technologies and instruments that are most appropriate (‘fit for purpose’) to different applications.
  • Follow technical developments and trends through collaboration with other FIG Commissions and other international organisations; participation in appropriate meetings; and the preparation of appropriate publications.
  • Support research and development and stimulate new ideas in the fields of expertise represented within the Commission.
  • Collaborate with manufacturers on the improvement of instrumentation and associated software.
  • Present and promote the work of the Commission and its working groups on an on- going basis at FIG Congresses, FIG Working Weeks, FIG Regional Conferences and other relevant technical meetings and in appropriate FIG and other media.

General

This work plan covers the development, use and integration of technologies for positioning and measurement and the associated standardisation, best practice and fundamental reference frame issues.  Complementing the FIG Council theme to tackle the global challenges, Commission 5 is well positioned and suited, along with many other Associations, to tackle the technological challenges we all face.

There will be ongoing cooperation with United Nations Agencies to address global problems such as sustainable development and humanitarian needs. The disciplines covered by Commission 5 will deliver solutions for the spatial aspects of these important global problems through its six working groups as follows.

  • WG 1 – Standards, Quality Assurance and Calibration
  • WG 2 – 3D Reference Frames
  • WG 3 – Vertical Reference Frames
  • WG 4 – GNSS
  • WG 5 – Multi-Sensor Systems
  • WG 6 – Cost-Effective Positioning

Specific activities aimed at developing countries include examination of Low Cost Surveying Technologies, assistance with implementation of modern Geodetic and Vertical Reference Frames and associated infrastructure and contribution to appropriate Continuing Professional Development programs.  

Specifically, to work closely with the International Association of Geodesy (IAG) and the United Nations Global Geospatial Information Management (UN GGIM) on the development of new models, standards and tools for implementing a Global Geodetic Reference Frame (GGRF) that includes aspects of the International Terrestrial reference Frame (ITRF) and the International Height Reference Frame (IHRF). The GGRF will serve as a global standard for all Nations to implement their respective national datums. As such this directly impacts FIG Members who must implement these new datums and the requirements to access them.  

In addition to the specific activities above, the Commission will support and contribute to FIG Task Forces and the Standards Network. The Commission will also respond to the FIG Council to address new challenges around Planet, People, Partnerships and Governance & Communications.
