Owning Organization:
Contact: Geoid charge
Resource classification: Data,Database
Research area  (1): Solid earth planet physics
Overview:
Using data of gravity and altitude of land and sea,
Geographical Survey Institute has been constructing
a precise gravity geoid model based on a global
gravity model obtained from satellite orbit
observation. The gravity geoid model, using
high-density gravity data, represents fine ups and
downs of the geoid with high precision. However,
long wavelength components of ups and downs of the
geoid showed systematic discrepancies from the
Japanese geodesic standard system. Therefore, to
construct a geoid model complying with the Japanese
geodesic standard system and offering basic data for
fundamental measurement, using geoid heights
obtained so as to comply with the Japanese geodesic
standard system from geoid measurements, the gravity
geoid model is compensated, and a geoid model
complying with the Japanese geodesic standard system
is generated.
