Publication number: 20040111213Abstract: There have been problems in the facility information management system arts because when a distance-based facility database is searched for the facility information by specifying the name and distance of a facility, the location and position of a specific facility must be found on a figure such as a map. Such a location is not easily pointed out especially when the facility is damaged. To overcome the above problems, the present invention relates the distance-based facility data with map data and allows a generation of graphical figure data to be overlaid on a map from the numerical data corresponding to the facility parameters stored in the distance-based facility data.Type: ApplicationFiled: November 10, 2003Publication date: June 10, 2004Inventors: Kazuaki Iwamura, Keiro Muro, Shintaro Hatsumoto, Shu Tezuka, Yukio Funyu

Patent number: 6728730Abstract: A figure management system in which plural kinds of figures concerning the same part to be managed are modified. The figure management system includes a figure DB for storing data of figures including topological figures, an attribute DB for storing object attribute data, input and output devices, and a computer for managing figure and object attribute data. An ID code common to features indicating the same object is assigned. On input of a new figure, feature-attribute matching is performed between a feature having no ID code on the new figure and existent object attribute data. If any inconsistency is found the feature is indicated as a discrepant feature or a renewed feature.Type: GrantFiled: August 8, 2000Date of Patent: April 27, 2004Assignee: Hitachi, Ltd.Inventors: Keiro Muro, Nobuhiro Ishimaru, Kazuaki Iwamura, Kazuo Tsutsui
