GEODESY / METROLOGY
Having now adopted a resolution confirming the importance of geodesy in sustainable development, the United Nations is encouraging its member states to use a modern reference framework which is accurate and accessible to all. The various GNSS systems (Global Navigation Satellite System) now available allow us to achieve levels of accuracy of just a few millimeters. Thanks to these systems, geodesy (the mathematical calculation of the Earth’s shape) now supplies cartographers and planners with reference points which become more accurate with each passing day. The regeneration of a country’s geodetic network is therefore absolutely fundamental for its development in view of the large range of sectors concerned: land administration, urban development, drainage and transport networks, but also the management of borders and therefore national security.
