Abstract

PURPOSE:To achieve an easy and accurate depiction of the sea bottom by indicating a submarine map on both sides of a shipls wake along therewith through an color-coded isobathic chart. CONSTITUTION:Image data measured with a sonar or the like are read out of an underwater cross-sectional image memory circuit 10 to extract a sea-bottom image with a sea-bottom extraction circuit 11, and the depth of each point of the sea-bottom image is converted into a graduated level through a depth-level conversion circuit 12 and applied to an indication position computing circuit 15 to which the true bearing of a ship from a bow direction detector 13, the current position thereof from a wake indicator 14 and other information are inputted. The sea-botton image converted into levels is alloted to a specified indication position to be memorized into a map image memory device 16 and the wake and a submarine map on both sides therof through a color coded isobathic chart are indicated on a device 14 through a color pattern generation circuit 18, an interface 17 and the like. This indication enables easy and accurate depiction of the sea bottom.
