Geodesy Capacity Development Workshop for the Americas on Transitioning to a Modern Geospatial Reference System
Work area(s)
Topic(s)
The Workshop for the Americas is jointly organized by the United Nations World Geodetic Centre of Excellence (UN-GGCE) and the Statistics Division of the Department of Economic and Social Affairs, with the collaboration of the United Nations Economic Commission for Latin America and the Caribbean (ECLAC).
The UN-GGCE envisions the future where all countries have a strong support for geodesy, enabling them – together – implement the General Assembly Resolution 69/266 and to accelerate the achievements of the Sustainable Development Goals and derive social, environmental and economic benefits. Key to achieving these benefits is the establishment of a modern GRS on which geospatial data can be aligned and combined for improved decision making.
This workshop is part of the Geodesy Capacity Development Workshop series, which serves as a platform to strengthen global geodetic capabilities, ensuring that all Member States are equipped to support sustainable development through accurate and reliable geospatial information. The workshops will be provided across the five regions: Africa, Americas, Arab States, Asia-Pacific and Europe. Each workshop will run for five days (Monday to Friday) and will take place in person.
The primary objectives of the workshops are to:
Santiago. ECLAC headquarters
