Abstract

Geoid is the equi-gravity potential surface. Gravimetric geoidal heights could be determined by the gravity observation values and geometric geoidal heights could be determined by the GPS ellipsoidal heights at benchmark station. In this study, both gravimetric geoidal heights and geometric geoidal heights were determined and compared in mountainous area. For the study, GPS surveying and gravity observation were accomplished at 1st and 2nd order levelling network located in mountainous area in Kyungsanbukdo and Chollanamdo.
