A comparative accuracy of Google Earth height with MyGeoid, EGM96 and MSL

Abstract

This study aims to provide understanding on the accuracy of height derived from Google Earth (HGoogleEarth) as compared to height obtained from Malaysian Geoid Model (HMyGeoid), Mean Sea Level (HMSL) and Earth Geoid Model 96 (HEGM96). Total of 50 established points with height acquired from HMyGeoid and HMSL were measured within UiTM (Universiti Teknologi MARA) Arau Campus. These points were also used to extract height from Google Earth and EGM96. Statistical results showed a good range of R2 between HGoogleEarth-HMyGeoid, HGoogleEarth-HMSL and HGoogleEarth-HEGM96 i.e. 0.823, 0.843 and 0.824 respectively. It shows HGoogleEarth strongly correlated with Hmsl.
