JODC Bathymetry Integrated Random Dataset (J-BIRD)

The data includes soundings, bottom sediments, low water lines, contour lines and coast lines. In addition, specific lines in the charts such as construction area and fish agriculture area were digitized since April 1993.

Each data may be identified by the mark in the first column of data record. As of April 1993, J-BIRD has plotting sheets digitized for Charts and Basic Maps of the Sea at a Scale of 1/10,000 or smaller for Coastal Area of Japan, and GEBCO Sheets at a Scale of 1/1,000,000 for the Northwestern Pacific of 0 to 48 Degrees North and 100 to 180 Degrees East.
