What in the world is geodesy? Geodesy is the study of Earth’s shape, gravity field, and rotation. Geodetic research defines the terrestrial reference frame. Geodetic techniques are used to quantify changes in the Earth’s surface and subsurface; ice sheets and glaciers; and oceans and atmosphere. Geodesy’s broader benefits include help with preparedness and mitigation of hazards and foundational support for space-based operations, navigation, communications, surveying, resource management, and national security.
The UNAVCO consortium consists of more than 100 US Full Members and over 80 Associate Members (domestic and international). Through their Geodetic Infrastructure and Geodetic Data Services Programs, UNAVCO operates and supports geodetic networks, geophysical and meteorological instruments, a free and open data archive, software tools for data access and processing, cyberinfrastructure management, technological developments, technical support, and geophysical training. The UNAVCO Education and Community Engagement Program provides educational materials, tools and resources for students, teachers, university faculty and the general public. They also provide summer internship experiences for undergraduate students interested in careers in geodesy and geosciences through our RESESS program.
