How Can Advances in GNSS and Geodesy Benefit the Geomatics Industry?

摘要

A keynote address at the XXV FIG Congress (Kuala Lumpur, Malaysia, 16-21 June) by Chris Rizos, IAG president, on 'Opportunities & Challenges for the Surveying Industry in a Multi-system GNSS World', identified five mega-trends influenced by developments in geodesy: the decades-long revolution unleashed by GPS; the forthcoming era of multi-constellation GNSS; the evolution of precise positioning from niche to mass markets; the importance of global geodetic reference frames; and the acceptance that geodesy is indeed an Earth observation science.
