Treatise on Geophysics, Volume 3

Geodesy, which is the science of measuring the size and shape of the Earth, explores the theory, instrumentation and results from modern geodetic systems. The beginning sections of the volume cover the theory of the Earth's gravity field, the instrumentation for measuring the field, and its temporal variations. The measurements and results obtained from variations in the rotation of the Earth are covered in the sections on short and long period rotation hanges. Space based geodetic methods, including the global positioning system (GPS) and Interferometric synthetic aperture radar (SAR), are also examined in detail. - Self-contained volume starts with an overview of the subject then explores each topic with in depth detail- Extensive reference lists and cross references with other volumes to facilitate further research- Full-color figures and tables support the text and aid in understanding- Content suited for both the expert and non-expert
