Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...
