FIG PUBLICATION NO. 64
Reference Frames in Practice Manual
Commission 5 Working Group 5.2 Reference Frames
May 2014
FIG GUIDE
Editor: Graeme Blick
The International Federation of Surveyors (FIG) Commission 5 is
responsible for assisting practising surveyors in FIG member associations to
apply Positioning and Measurement technologies efficiently and effectively
in their day-to-day survey activities. One of the most significant
technologies to emerge in recent decades has been Global Navigation
Satellite Systems (GNSS). The rise of such a global technology has
highlighted the need for countries to move from locally defined geodetic
datums to more global datums based on the International Terrestrial
Reference Frame. This FIG publication is
a response by Commission 5 to this trend by bringing together a series of
fact sheets to better inform surveyors about some of the key issues they
need to consider as they realign and upgrade their professional
knowledgebase.
During my time in Commission 5 as a Working Group Chair and then as
Commission Chair, we placed special emphasis on improving the availability of
factual and accessible information about reference frame matters, especially for
surveyors and decision makers in developing countries. That work was extended
and improved by the Chairs of Commission 5 who followed me, Rudolf Staiger and
Mikael Lilje. A special feature of the Commission’s work in recent years was a
series of workshops on reference frame matters that were attached to FIG and
allied events in developing countries.
FIG would like to acknowledge the partnership under our MoU with the UN
Office for Outer Space Affairs, which saw the UN Office fund developing country
delegates to attend several of the international workshops that form the basis
of this publication. That interaction was very important in identifying the
specific topics that this publication should cover and help surveyors to better
understand.
An extremely important aspect of this publication is as a concrete
demonstration of the value of the increased cooperation in recent years between
FIG and its sister association, the International Association of Geodesy (IAG).
The international workshops and resulting fact sheets have seen a very close
collaboration between internationally recognised experts from both FIG and IAG
and it is hoped that such collaboration will continue to grow and deepen in the
future. FIG would like to especially acknowledge the role played by IAG
President Chris Rizos as a driving force behind IAG’s commitment to our
increased cooperation.
In closing FIG and its Member Associations are very grateful to the experts
from both FIG and IAG who generously volunteered their time and effort to
support the international workshops and especially to those who went on to
author the fact sheets that make up this important publication. Special mention
goes to Commission 5 Vice-Chair Graeme Blick, who coordinated the development of
this publication under the leadership of Commission Chair Mikael Lilje and with
the very able administration of Commission Vice-Chair Rob Sarib.
