Abstract: This paper analyzes the different reference frames and map projections which are involved in coastal space data-integration, and proposes some effective methods for unifying different reference frames and transforming different map projections. Particularly, the relation between the order of a polynomial and control points is discussed. The methods proposed for map projection transformation in this paper can be used in other fields, e.g. integration of landform and seabed.
