The Taiwan geoid model was computed using the standard "remove-restore" technique. The residual geoid undulations were estimated via 1D FFT on the residual gravity anomalies, i.e. observed values, minus the EGM96 global geopotential model and the RTC effect. The geoid model covers the area 21.55°< lat.< 25.50°, 119.50°< long.< 122.45° and the grid spacing is 3' both in latitude and in longitude.
