## Abstract

With Geodetic method, the accuracy of geoid model between Keelung and Kaohsiung point is about 5.93 cm. All sea surface topography differences(Δ SST) calculated by gravity recovery data was processed with three part(A, B and C)sets. A set result shows that from Keelung connected point to calculate Keelung(Taiwan)- Liugiu Shiang (isolated island) Δ SST are estimated to be 7.61 ± 8.50 cm, and from Kaohsiung connected point to calculate Keelung(Taiwan)-Liugiu Shiang(isolated island) Δ SST are estimated to be 1.68 ± 8.50 cm. B set result shows that from Keelung connected point to calculate Keelung(Taiwan) - Greenisland(isolated island) Δ SST are estimated to be 46.90 ± 8.50 cm, and from Kaohsiung connected point to calculate Keelung(Taiwan) - Greenisland (isolated island) Δ SST are estimated to be 41.01 ± 8.50 cm. B set result shows that from Keelung connected point to calculate Keelung(Taiwan) - Lanyu(isolated island) Δ SST are estimated to be 103.36 ± 8.50 cm, and from Kaohsiung connected point tocalculate Keelung(Taiwan) - Lanyu (isolated island) Δ SST are estimated to be 97.42 ± 8.50 cm.
