Numerous special events were held to celebrate the 150th anniversary of the IAG during the IAG 2013 Scientific Assembly in Potsdam, Germany.
The IGS sponsored two such special events, which were recorded and are available below:
IAG History Retrospective - a series of presentations covering the three major phases of the history of IAG: Regional Project to International Organization, World Wars and Aftermath, and The Space Age.
Ignite IAG - a series of five-minute presentations on a variety of topics relating to geodesy and the 150 year history of the IAG.
