Hydrographic imaging for underwater environment modelling

The article presents the research on hydrographic data integration for the purpose of environment modelling. The approach taken by the authors assumes three basic sources of underwater information: sonar images, bathymetric grid and contour map of magnetic anomaly derived from hydrographic surveys conducted in marine waters. The article discusses the characteristics of each set of data and presents the hierarchical model of proposed integration. The process of integration is discussed together with some issues related to input data resolution. Obtained results are presented in a form of a 3D visualization model.
