PROBLEM TO BE SOLVED: To provide a track data display program, a track data display method, and a track data display device capable of easily extracting a case of taking an evasive action by a ship.SOLUTION: A track data display program causes a computer to execute a process for extracting specific track data about a set of specific ships whose relative distance is within a predetermined range from among pieces of track data relating to a plurality of ships. A track data display program causes the computer to execute a process for extracting the site at which the distance between tracks becomes the minimum from the specific track data. The track data display program causes the computer to execute the process for displaying the point data of the ship arriving first at the extracted site from among the set of specific ships relating to the extracted site in association with the point data of the other ship at the time in which the ship having arrived first arrives at the extracted site.SELECTED DRAWING: Figure 10

    【課題】船舶が回避行動を取った事例を容易に抽出可能な航跡データ表示プログラム、航跡データ表示方法および航跡データ表示装置を提供する。【解決手段】航跡データ表示プログラムは、コンピュータに、複数の船舶に関する航跡データのうち、相対距離が所定の範囲内となる特定の船舶の組についての、特定の航跡データを抽出する処理を実行させる。航跡データ表示プログラムは、特定の航跡データから、航跡間の距離が極小となる箇所を抽出する処理を実行させる。航跡データ表示プログラムは、抽出した箇所について、特定の船舶の組のうち、抽出した箇所に先に到達した船舶の地点データと、先に到達した船舶が抽出した箇所に到達した時刻における他方の船舶の地点データとを対応づけて表示する処理を実行させる。【選択図】図10
