According to the geospatial referential relationship of the marine geophysical data gathered from the same survey area, the author achieves 3D integration of the same area's multi-beam and sub-bottom profile data in GIS by using survey line vector data as topological entities. The implementation of integration mainly utilizes the following functions in GIS, the supporting function of multi-kinds spatial data such as raster and vector, the powerful secondary development function, and the topology construction function of spatial data. The main procedures include pre-processing bathymetric data to get submarine DTM and creating 3D seafloor stratum slices by processing the sub-bottom profile data. And then achieves the 3D visual display of associations between multi-beam and sub-bottom profile by spatial topological relation in GIS. On the basis, the author also gives future prospects on the integration method and model of the multi-source marine geophysical data.
