6 Conclusion
A tidal datum is a standard water level defined by a particular phase of the tide.
Tidal datum is used as a reference level for measuring local water levels and
should not be extended into areas having differing oceanographic characteristics
without substantial measurements. A number of techniques and datasets are
available to delineate the littoral zone. The bathymetric and topographic data are
used to define the terrain model. Meanwhile, the tides observation data are used to
derive the tidal model and tidal line.
Based on the analysis of tidal datum that has been conducted, it shows that is a
great potential to use LAT as reference level for marine cadastre. This will benefit
the realization of marine cadastre in Malaysia due the availability of com-
mencement point for parcel right. However, to develop the homogenous datum for
land and sea, there is a need to develop a model for defining the relationship
between different vertical reference surfaces. Large scale map of LAT tidal line
and littoral zone for Malaysia is important towards the realization of marine
cadastre in Malaysia.
