Abstract:On the basis of requirement of water information presentation of the digital ocean system, a method for cubic water data modeling and building is proposed. Based on the 3DGIS software package, such as Terrasuite and EV-Globe, sea surface modeling, water information presentation, and virtual ocean scenery building are studied, especially, the presentation of water feature with "cubic grid". The study brings new thoughts for the building of the digital ocean prototype system.
Keywords:digital ocean  water data model  cubic grid  3D-dimensional visualization  sea surface modeling
