Because of the complexity of sea's environment and the difficulty to gain data,the sea three-dimensional visual research always concentrates on the sea scene and the seabed terrain aspect,and the related visual research of seabed sediment should be strengthened.Through the establishment of seabed sediment database,the seabed sediment visual simulated environment is built.Based on water depth data and multi-beam data,the basic three-dimensional seabed terrain is established and free isobaths automatic production is realized.And based on the drill hole data and the stratum drag net sample,the seabed sediment three-dimensional visualization is initially realized.Through the effective integration,the 3-D visual simulation system of seabed sediment is constructed,which can develope marine resource,sea economy and maintain country sea rights and interests.
