Information systems GPS receivers Geoid model gave information in determination of orthometric height by knowing the ellipsoidal height. This ellipsoidal height using Global Navigation Satellite System (GNSS) technology. The main objective is to determine precise geoid models. There are several of method in determine geoid at any country such as Remove- Compute-Restore (RCR) method. In this study, the Least Square Modification Stokes' (LSMS) approach by Royal Institute of Technology, (KTH) had been the aim for the evaluated in determine gravimetric geoid model in Johor region. In order to increase the accuracy of geoid model. Global Geopotential Model (GGM) along with Digital Elevation Model (DEM) are need. So that it achieved in study focus which is evaluation of DEM and GGM. The result of this study is one of three GGM were evaluate and ITU_GGC16 is the most precise global model that produce Root Mean Square Error (RMSE) with 0.22m over 3367 gravity points. In additional, in DEM evaluation, the SRTM30 show the RMSE with 7.12m. Furthermore, the precise gravimetric geoid model show that Aster using ITU_GGCI6 show precise than SRTM30 and SRTM90 with 1.365m. The comparison between RCR method where JUPEM used and KTH approach show that the LSMS method is better in determine precise geoid model for Johor region. 2018 Thesis https://ir.uitm.edu.my/id/eprint/22561/ https://ir.uitm.edu.my/id/eprint/22561/1/TD_AFIQAH%20ZOL%20AP%20R%2018.5.PDF other en public degree Universiti Teknologi MARA, Perlis Faculty of Architecture, Planning and Surveying Pa'suya, Muhammad Faiz
