International Association of Geodesy Commission 1: Reference Frames Definitions, establishments, maintenance, and improvements of geodetic reference frames Advance terrestrial and space observation techniques International collaboration for deployment of geodetic networks

International Association of Geodesy Commission 1: Reference Frames Collaboration with international services and geodetic agencies on space geodesy and reference frames Maintain / improve a reference frame that is important for global change studies

International Association of Geodesy Reference Frames for Applications in Geosciences Theory and Concepts Measurement accuracy Station position time variations Geodetic Measurement Techniques SLR, VLBI, Doris, GNSS Strengths and weaknesses Geophysical model limitations

International Association of Geodesy Reference Frames for Applications in Geosciences Regional Reference Frames Role of sub-global reference frames Coordinating national and regional efforts Reference Frames in Geoscience Societal needs Scientific goals

United Nations-Global Geospatial Information Management Aims and Objectives of UN-GGIM Development of a global geodetic reference frame Development of a global map for sustainable development Geospatial information to support development Develop a knowledge base for geospatial data

United Nations-Global Geospatial Information Management Aims and Objectives of UN-GGIM Creation and adoption of standards for geospatial community Legal and policy frameworks for critical data; privacy Identify fundamental data sets and corresponding metadata Define principles on managing geospatial information

United Nations-Global Geospatial Information Management 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
