Technical Seminar on Vertical Reference Frames in Practice
Singapore, 27-28 July 2015
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
of the highlights of the seminar was the dinner held on the first

by the Bay and provided an opportunity to sample a number of local
dishes and continue the networking.
