Abstract

A vertical datum is the core information needed in deriving height or elevation of points on the surface of the earth. This information used as a starting point or zero value of height. Currently, various vertical datum used as a zero level in determination of height and depth in Peninsular Malaysia. Considering the current needed in seamless geospatial information across land and sea area, deep understanding on the discrepancies of vertical datum is necessary. In this paper, height of points referred to Peninsular Geodetic Vertical Datum (PMGVD), Local Mean Sea Level (LMSL) and Chart Datum (CD) are investigated. The discrepancies of height referred to the various datum also analysed.
