Patent ID: 8576249

Claim:
A map display device, comprising: a map display control unit that brings up a map on display at a display monitor; a stormy weather condition information reception unit that receives stormy weather condition information; a stormy weather condition information display control unit that provides a storm path forecast, indicating a predicted path of a storm, based upon the stormy weather condition information by superimposing the storm path forecast over the map on display at the display monitor; and a predicted position selection unit that selects a first predicted position and a second predicted position among a plurality of predicted positions that the storm is estimated to assume; wherein: the predicted position selection unit selects, as the second predicted position, a predicted position corresponding to a latest time point among the plurality of predicted positions and selects, as the first predicted position, a predicted position closest to a halfway point between the current position of the storm and the second predicted position; and the stormy weather condition information display control unit displays the storm path forecast by using two fan-shaped ranges, one centered on the current position of the storm with an arc thereof passing through the first predicted position and another centered on the first predicated position with an arc thereof passing through the second predicted position.
