Abstract: It is necessary to design the vessel’s track for resource survey on the sea, and the route of sailing and workload of survey will be reflected by the vessel’s track. This paper enumerates several manners for data collection and a method for data extraction, then making use of Global Mapper to plot the vessel’s track which can change color,thickness and otherwise,while trend of the depth will be revealed. The vessel’s track that is plotted by Global Mapper will provide reference for checkout of the datum more reliable and effective.
