Description:
The GSIGEO2000 model is a hybrid geoid for Japan of the Geographical Survey Institute (http://www.gsi.go.jp). This model is provided on a 1'x1.5' grid and it is referred to the GRS80 ellipsoid in the ITRF94 frame (epoch 1997.0), i.e. the Japanese Geodetic Datum 2000 (JGD2000). It is computed by fitting the JGEOID2000 gravimetric geoid model to the nationwide net of GPS/levelling data via Least-Squares Collocation. The resulting hybrid model is internally and independently assessed, showing an estimated precision of 4 cm throughout nearly the whole region.
