United Nations General Assembly
Adopted first resolution recognizing the importance of a
globally-coordinated approach to geodesy
Resolution – “A Global Geodetic Reference Frame for Sustainable Development”
United Nations-Global Geospatial Information Management
United Nations General Assembly
Co-sponsored by 52 Member States
Supports sustainable development, policymaking, climate change monitoring, natural disaster management
Will enable a wide range of applications - transportation, agriculture and construction
