SGEOID09 is a geometric geoid model for Singapore. A complete re-levelling of the Singapore network was carried out, together with GPS observations in RTK mode. After a proper outlier rejection, the SGEOID09 model was computed by interpolating 406 GPS/levelling benchmarks with a stepwise multiple regression. According to its accuracy, the SGEOID09 model is suited in engineering applications which can accommodate a height uncertainty of 5 cm.
