Opis

This volume includes a selection of papers presented at the IAG international symposium Gravity, Geoid and Height Systems 2012 (GGHS2012), which was organized by IAG Commission 2 Gravity Field with the assistance of the International Gravity Field Service (IGFS) and GGOS Theme 1 Unified Global Height System. The book summarizes the latest results on gravimetry and gravity networks, global gravity field modeling and applications, future gravity field missions. It provides a detailed compilation on advances in precise local and regional high-resolution geoid modeling, the establishment and unification of vertical reference systems, contributions to gravity field and mass transport modeling as well as articles on the gravity field of planetary bodies.
