1. A situation display device adapted to be equipped in a ship, the device comprising:

  • a controller comprising memory and one or more processors configured to execute;

    an observation data acquiring module configured to acquire observation data obtained by observing a direction and a magnitude of at least one of meteorological phenomena and hydrographic phenomena, along with information of observed locations of the observation data from a beacon receiver and a GPS receiver, wherein the meteorological phenomena and hydrographic phenomena include at least one phenomenon selected from the group consisting of a wind direction, a wind speed, an atmospheric pressure, and a wave height; and

    a data selecting module configured to select the observation data obtained at the observed location that is within a predetermined range from a set course of the device; and

    a display unit configured to display, when a display screen is oriented vertically, on a bottom side of the display screen, a three-dimensional graphic with a location of the device with respect to the course, and display the course linearly such that a traveling direction thereof extends upward from the bottom side,wherein the display unit displays, in an upward tapering shape, an area having a predetermined range from the course to a perpendicular direction to the course, and displays the selected observation data as an observation data display part at a position on the display screen that indicates a relationship between the course and the observed location of the selected observation data, the displayed position of the device in the perpendicular direction being corresponding to an offset amount of the location of the device from the course, and the observation data display part including a visually distinguishable symbol that graphically illustrates the direction and the magnitude of the selected observation data relative to the course; and

    wherein a size of the symbol of the observation data display part with respect to the direction and the magnitude is adjusted according to the observed location on the display screen.
