Geodesy: The Challenge of the Third Millennium



Like many of my colleagues in the burgeoning field of geodesy I primarily apply geodetic techniques toward illuminating tectonic and geophysical problems. In doing so, I must confess that I often take the underlying methods of measurement and analysis for granted, assuming that surface velocity and surface strain observations are the fundamental data of our science.

Geodesy: The Challenge of the Third Millenniumreminds me that the science of geodesy encompasses a much wider range of endeavor upon which recent innovations depend greatly. It reminds me, too, that the derived geodetic products I use are the result of a long sequence of scientific discovery and innovation in fields as disparate as statistics, electronics, mathematics, and basic physics. This discovery continues today in the work of the authors who contributed to this volume.
