Add to ORKGPrecise determination of local geoid is of particular importance for GPS heighting. A geoid can be accurately obtained with an optimal combination of a global geo-potential model, local gravity measurements, and the topographic information. This paper uses the remove-restore technique to construct the Hong Kong gravimetric geoid. The EGM 96 geo-potential model, over 600 gravity measurements and 500m grid DTM were used. The results were compared with the geoid heights at 31 checkpoints derived from GPS levelling data. It is shown that the constructed gravimetric geoid has an accuracy of about 20mm.Department of Land Surveying and Geo-Informatic
