PROBLEM TO BE SOLVED: To solve a problem wherein no system for local guide capable of acquiring the whole local three-dimensional structure, and capable of providing a landmark or scene information serving as a mark for acquiring the current position exists, and a problem wherein no means capable of collecting the landmark or scene information required for the local guide of the three-dimensional structure and capable of digitalizing it immediately to be accumulated exist.;SOLUTION: Both information of the whole local three-dimensional structure and detail information thereof are exhibited to be easily acquired, by providing a means for exhibiting three-dimensional moving and usual two-dimensional moving by different methods. A collection cost for a data required for the local guide is reduced by providing a means for inputting and editing the information of the three-dimensional structure, based on a local top view, and a means for supporting acquisition of the detail information.;COPYRIGHT: (C)2007,JPO&INPIT
