Working Group 5.1
Standards, Quality Assurance and Calibration
Policy Issues
Influence the development of standards affecting positioning and
measurement instruments and methods, in collaboration with the FIG
Standards Network and through participation in the relevant
technical committees (TCs) of the International Standards
Organisation (ISO) and other appropriate bodies.
Acceptance controls, quality assurance and certification and
their impact on the surveying profession.
Testing and calibration of measuring instruments.
Assist other Commission Working Groups to implement Standards
from TC 172/SC 6 and ISO TC211 as appropriate.

What we are working on -
Guide for the expression of uncertainty in measurements
(GUM) for surveying
Connection to ISO TC211
A dedicated publication regarding the implementation of
the “Guide for the expression of uncertainty in
measurements” (GUM) for surveying
What's New
ISO TC 211 is concerned with standardization in the field of digital
geographic information. This commission 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, analysing, accessing, presenting and transferring
such data in digital/electronic form between different users, systems and
locations. The work links to appropriate standards for information
technology and data where possible, and provides a framework for the
development of sector-specific applications using geographic data. Nic
Donnelly, from Land Information New Zealand, is the FIG liaison to TC211.
One item of interest to Commission 5 is the start of a new standard for
Discrete Global Grid Systems (DGGS), ISO19170. This work is undertaken
jointly with OGC, which has already published a standard on DGGS. DGGS are
designed to support big-data processing at global scales, providing a
scalable means of assigning location to data at any desired resolution.
ISO/TC 172/SC 6 deals more closely with the hands on details related
to using classical surveying instruments. These standards deal with field
procedures for testing geodetic and surveying instruments such as
theodolite, total stations levels and GNSS in real-time kinematic (RTK).
Ingo Neumann from the Geodätisches Institut Leibniz Universität Hannover
is the FIG representative to ISO/TC 172/SC 6. One key standard where work
is presently concentrated is ISO/DIS 17123-9 - Optics and optical
instruments -- Field procedures for testing geodetic and surveying
instruments -- Part 9: Terrestrial laser scanners. Another is the
republication of ISO 17123-5:2018 Optics and optical instruments -- Field
procedures for testing geodetic and surveying instruments -- Part 5: Total
stations with updated formulas and an improvement in the layout. Finally,
the new Standard ISO 9849 is published – Optics and optical instruments --
Geodetic and surveying instruments – Vocabulary. This standard is very
important for FIG because it summarizes vocabulary used in the field of
geodetic and surveying sensors and instruments. It has been extended to
include terms in the area of multi-sensor-systems of the future.
