Global Geodesy Forum on Earth Day 2021

April 22 12:30 pm 2:00 pm SAST

The Global Geodesy Forum will be convened virtually on Earth Day, 22 April 2021. Titled “The power of where: The value of geodesy to society”, it will highlight the important role geodesy has in providing safer and more resilient communities, in particular, to measure the cause and effect of sea level rise, storm surges and tsunami.

The Forum will explore the economic benefits enabled by an accurate and reliable Global Geodetic Reference Frame (GGRF), and the role geodesy plays in assisting developing countries with efficient and effective land management. In addition to demonstrating the benefits geodesy provides to our world, the forum will also shine a light on some of the risks associated with the GGRF, including the degradation of geodetic infrastructure and a lack of access to accurate coordinate reference frames and precise positioning in developing countries. The forum will be open to anyone interested in participating.

The Forum moderator will be Nicholas Brown (Co-chair, UN-GGIM Subcommittee on Geodesy)
