Preface
The Committee on Geodesy (COG) of the National Research Council (NRC) has long been involved in evaluating the opportunities for new insights and applications that accurate geodetic measurements offer the earth, ocean, and space science communities. With the development of the Global Positioning System (GPS) and the possibility of having very precise aircraft navigation, new scientific opportunities exist for high-resolution surveys of the topography and gravity field of the Earth. To assess these new opportunities and the ways in which airborne techniques using GPS might complement other ground-and space-based techniques, COG held a workshop on airborne geophysics in July 1993. The goals of the workshop were as follows:
- to evaluate the current status of airborne geophysics and precise positioning techniques;
- to identify the scientific objectives that are made possible by integrating aerial measurements and precise positioning techniques; and
- to propose strategies for expanding and optimizing the future development of airborne research platforms, aircraft-based measurements, and precise positioning.
A steering committee of six individuals from COG with expertise in both the instrumentation and the scientific aspects of airborne geophysics planned the workshop. Steering committee members were Robin Bell (chair), Thomas Herring, Christopher Jekeli, J. Bernard Minster, Richard Sailor, and David Sandwell. Held on July 12–14, 1993, in Washington,
