GIS Marine information system based on GIS

摘要

The present invention relates to a marine information system based on a GIS. Interference and dissipation of sound waves are minimized by collecting topological/geographical information of a seabed based on sound waves emitted from a sensor installed on the seabed. Costs for observing a seabed and probability of marine pollution are minimized by reusing equipment as a sensor, having finished emission of sound waves, is floated to the surface of the sea and retrieved. In addition, the marine information system based on a GIS has a sensor fixation means, tightly fixates and installs a sensor on a seabed to prevent the sensor from being moved by tide, and thus makes more precise detection possible. Resource and costs can be saved by salvaging, retrieving, and reusing some components of the sensor fixation means.
