A visualization system of marine environmental data

On behalf of the "Bundesamt für Seeschiffahrt und Hydrographie" in Hamburg and in cooperation with the "Institut für Ostseeforschung Warnemünde", it was developed a VIsualization System for MARine environmental data, called VISMAR. The objectiv was an interactive computer supported system, which allows scientist to use methods of visual data analysis on geographical maps in an easy way. The interactive system support also the dataselection with speciell reference to time, geographic coordinates, depth and measured parameters. Data that could be visualize, are measurements of e.g.: temperature, salinity, disolved gases, nutrients, pollutants, current, phyto- and zooplankton, other biomasses, magnetic values, topographie and sediment. We describe the main features of the system and show its usability by a number of applications in oceanography.
