IAG Statement on Ukraine

The International Association of Geodesy and its services strongly condemn the unprovoked and premeditated Russian invasion of Ukraine. We are deeply troubled by the loss of life and hundreds of thousands of civilians becoming refugees, and are very concerned about the safety and well-being of our scientific colleagues in Ukraine. We strongly request that the responsible people stop the military actions immediately.
