The purpose was to perform long distance triangulation on a worldwide basis. This allowed the interconnection of national terrestrial triangulation networks on continental scales and connection between continents. The dataset was a key element in the realization of the World Geodetic System (WGS 72). The International Association of Geodesy also initiated international cooperation on continental scales. Observations for the West European Satellite Triangulation Project (WEST) began in 1968 and interconnected 40 sites in Europe by simultaneous photography of the same satellite from two or more sites. Tromsø, Norway and Catania, Italy were the north and south terminal stations for the baseline in Europe. The Geographical Survey of Norway participated in the observational work in Tromsø, Svalbard, and Oslo. Photographic plate measurements of the European sites were performed in Germany. Analysis of the observational data was conducted in the USA and Germany.
