Beskrivning

The book contains the papers presented at the IAG Symposium on Vertical Reference Systems held in Cartagena, Colombia, in February 2001. It covers the status report of existing height reference systems and the latest steps towards the establishment of a unified vertical reference system. Classical and modern height determination techniques are included as well as the determination of height reference surfaces like sea level and geoid. Emphasis is also given to the variations of the reference systems with time, i.e., sea level changes and geodynamic deformations.
