PURPOSE:To grasp intuitively and easily information of both information of the wake of a ship and weather, fishery, or the like simultaneouslyby displaying the wake of the ship on a single color CRT screen together with longitudinal lines and latitudinal lines and displaying compositely weather, fishery information, etc. in a sea area corresponding to the display range simultaneously with said display. CONSTITUTION:The wake is displayed on the scrren of a color CRT display device 4 together with longitudinal lines and latitudinal lines by video signals transmitted from a video signal generator 3. An antenna 5 and a receiver 6 receive radio signals including weather information, fishery information, etc. which are sent from a transmitting station on the ground or a artificial satellite. One- picture components of data or received still pictures are stored in a received data storage device 7. A picture position data correcting device 8 corrects data stored in the storage device 7 as a function of the position on longitude and latitude and converts this data, and data is stored again. A display data extracting and processing device 9 extracts a part of picture data stored in the correcting device 8 and compounds data and sends back data to an operation controller 1. |
