The number of fisherman in Japan is declining. As people currently involved in the fishery industry grow old and retire fewer and fewer young people come into the industry to replace them and it is said that Japan may face a fisheries crisis within a few decades. Under these circumstances, it is important that the efficiency of coastal resource management be increased in order to conserve the present catch. This can be done with the help of Information Technology. Scientific information about the spatial and temporary dynamic nature of marine habitats is especially important in coastal resource management and Geographic Information System (GIS) is a tool that can be used to assess and manage this kind of marine information. In order to get marine information for GIS effectively and efficiently the authors have developed a general-purpose real-time sensor platform called "MovaCom (Movable Computer)". In this paper, experimental data for a 3-D topographic map of a seabed obtained by MovaCom combined with fishing echo sounder is reported to show the effectiveness of using MovaCom. The experimental data is in good agreement with measurements of multi-beam echo sounder and it is accurate to within approximately 1m.
