Reference Frames in Practice Manual

FIG
[ Link to FIG ]

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.
