To provide a system capable of efficiently managing three-dimensional point group data.SOLUTION: Three-dimensional point group acquisition means 22 of a terminal device 20 acquires outline region data of a desired feature from an attribute data server device 60. The three-dimensional point group data acquisition means 22 accesses a first point group server device 40a on the basis of the acquired outline region data of the feature, and acquires three-dimensional point group data included in the region as first three-dimensional point group data. Further, the three-dimensional point group data acquisition means 22 accesses a second point group server device 40b on the basis of the acquired outline region data of the feature, and acquires three-dimensional point group data included in the region as second three-dimensional point group data. Three-dimensional mode construction means 24 constructs a three-dimensional shape of the feature on the basis of the acquired first three-dimensional point group data and second three-dimensional point group data.SELECTED DRAWING: Figure 1

    【課題】三次元点群データを効率よく管理することのできるシステムを提供する。【解決手段】端末装置20の三次元点群データ取得手段22は、所望の地物の外形領域データを、属性データサーバ装置60から取得する。三次元点群データ取得手段22は、取得した地物の外形領域データに基づいて、第1点群サーバ装置40aにアクセスし、当該領域に含まれる三次元点群データを第1三次元点群データとして取得する。さらに、三次元点群データ取得手段22は、取得した地物の外形領域データに基づいて、第1点群サーバ装置40bにアクセスし、当該領域に含まれる三次元点群データを第2三次元点群データとして取得する。三次元モデル構築手段24は、上記取得した第1三次元点群データと第2三次元点群データに基づいて、当該地物の三次元形状を構築する。【選択図】図1
