Abstract:
IAG SC2.4e is a sub-commission of SC2.4 and it promotes geoid gravity field modeling in the Asia Pacific region. In October 2020 and October 2022, two online workshops were organized by the members of SC2.4e, followed by the publications of two journal special issues dedicated to the workshops. This paper reports the result of IAG SC2.4e over 2019-2023 and show examples of gravity data collection, processing and applications to geoid modeling in Australia, China, Hong Kong, India, Indonesia, Japan, Malaysia, Nepal, New Zealand, Philippines, South Korea, Thailand and Taiwan.
