The 18 papers of the book give a comprehensive overview over recent advancesof geodetic research in Latin America. The book is divided in three parts: 1. Geodetic and gravimetric control in Latin America 2. Regional Gravity and Geoid Determination 3. Geodynamic Research Projects The Symposium was held in Vienna, August 1991, at the General Assembly of the International Union of Geodesy and Geophysics.
