Description
Ｄ座標はリンクの始点から当該Ｚ構成点までの距離としているが、Ｄ座標の“０”となる基準値は上記差分表現と同様に限定するものではない。 D coordinate is the distance to the starting point or we those wherein Z configuration point of the link, the reference value to be "0" of the D coordinates is not limited as above differencing.
図１３に示すように、図５に示された実施の形態１のデータ構造ではＺ構成点の位置は経度、緯度にて示しているが、実施の形態４ではＸＹ関連成分としてＺ構成点ＰＺｊの設定間隔と始点からのＺ構成点ｊの設定順序とを含ませ、Ｚ構成点のＸＹ方向の位置を間接的に算出可能にしている。なお、他のデータ構造は図５で示した実施の形態１と同様であるため説明を省略する。 As shown in FIG. 13, in the data structure of the first embodiment shown in FIG. 5, the position of the Z constituent point is indicated by longitude and latitude, but in the fourth embodiment, the Z constituent point PZj is used as the XY-related component. And the setting order of the Z constituent point j from the starting point are included so that the position of the Z constituent point in the XY direction can be indirectly calculated. Other data structures are the same as those in the first embodiment shown in FIG.
このように、実施の形態４の３次元道路地図データ処理システムにおけるＺ構成点作成部２５は、ＸＹ関連成分として、始点〜終点間にＺ構成点を設ける距離間隔と、始点からの当該Ｚ構成点の設定順序とすることにより、各Ｚ構成点に必要な情報はＺ成分のみにすることができるため、実施の形態１以上に格納用３次元道路地図データの情報量を削減することができる。 As described above, the Z composing point creation unit 25 in the three-dimensional road map data processing system according to the fourth embodiment includes the distance interval in which the Z composing point is provided between the start point and the end point as the XY-related component, and the Z configuration from the start point. By adopting the point setting order, the information necessary for each Z component point can be only the Z component, so that the information amount of the storage three-dimensional road map data can be reduced as compared with the first embodiment. .
