Unified Global Height System - GGOS Theme 1

The definition and realization of a World Height System (WHS) is a fundamental requirement
of GGOS (Global Geodetic Observing System). In the same way as the ITRS/ITRF provides a
high precision geometrical reference frame, the WHS shall provide the corresponding high
precision physical reference frame for studying the system Earth.

ICP 1.2 is a common project of IAG Commission 1 and 2. From beginning of 2010 the
activities of ICP1.2 were integrated in GGOS as Theme 1.
