	Technical Seminar on Vertical Reference Frames in Practice 
		Singapore, 27-28 July 2015 
		Introduction 
		The Technical Seminar on Vertical Reference Frames in Practice was 
		held in Singapore on 27-28 July 2015. The seminar had a particular focus 
		on vertical reference frames, in response to requests from the region. 
		This complemented a previous seminar held in Manila in 2013, which 
		focussed on 3D frames. 
		The workshop was organised by FIG Commission 5, in conjunction with 
		the International Association of Geodesy (IAG), the International 
		Committee on GNSS (ICG), the United Nations Initiative for Global 
		Geospatial Information Management for Asia-Pacific (UN-GGIM-AP) and the 
		Singapore Land Authority (SLA). 
		The seminar was held in conjunction with the 13th South East Asian 
		Survey Congress at the Marina Bay Sands Convention Centre. Local 
		organisational support was provided by Victor Khoo and Richard Loo of 
		the Singapore Land Authority.

		Networking and Social Events 
		There were excellent opportunities to network and socialise during 
		the lunch and tea breaks, which the participants took advantage of. One

		evening, facilitated by our Singaporean hosts. Dinner was held at Satay 
		by the Bay and provided an opportunity to sample a number of local 
		dishes and continue the networking.
