Abstract

Abstract:

Marine survey data increase steadily with the continuous progress in global marine surveying and the development of marine exploration techniques. So far various specialized softwares have been used to display/plot all types of marine survey data for visualization. However, it is necessary to create a data visualization tool for quick data display and analysis for today's global ocean observation and seafloor exploration. Here, for visualization and simultaneous display of multi-type data, we design and develop (using Matlab) a simple, easy-to-use data visualization and graphic user interface called OceanVis1.0. Using OceanVis1.0, all types of marine survey data—global bathymetric data, marine gravity anomaly data, marine magnetic anomaly data, earthquake waveform data, etc.—can be easily visualized for mapping analysis, and comprehensive visual analysis of key oceanic areas can be achieved. In OceanVis1.0, multi-type survey data can be displayed using 2D lines and 3D space variations, and visual manipulation such as zoom and rotation is also easy to do. For multi-beam, marine gravity and magnetic anomaly data, free cutting 2D lines and graphic output without saving intermediate graphics provide real-time visualization and a quick display. Meanwhile, OceanVis1.0 allows quick display and analysis of marine exploration data obtained from survey voyages, thus can be used in designing ship surveying lines for a specific research area.

Key words: data visualization, graphic user interface, global ocean seafloor data, OceanVis1.0
