Patent number: 5864632Abstract: A map editing device capable of easily supplementing insufficient information and easily re-measuring an object that has changed. An image, a perspective projection map, a projection center and a projection angle are displayed in superposition. When a user manually changes the projection center and the projection angle, a perspective projection map after this change is generated and displayed. When a perspective projection map capable of obtaining insufficient information is determined, an imaging condition capable of obtaining the insufficient information can be determined based on the projection center and the projection angle at that time. The insufficient information can be easily supplemented if the arrangement is so made as to acquire images conforming with the imaging condition. The condition necessary for re-measurement can be determined.Type: GrantFiled: September 30, 1996Date of Patent: January 26, 1999Assignee: Hitachi, Ltd.Inventors: Yukio Ogawa, Tomoko Hatakeyama, Shigeru Kakumoto

Patent number: 5544052Abstract: In a digital cartographic system for processing geographic information, a map projection of a map is converted. The map projection transformation is carried out with a coordinate value in which longitude and latitude are set to a center by way of a linear interpolation so as to simplify a calculation required for transforming the map projection, and also not depending upon a map projection to be converted. Also, after the transformation process operation, a reference line such as longitude/latitude and an equiangular line is superposition-displayed/overlapping-displayed in order to assist an analysis, in response to a demand. In accordance with the present invention, a map can be shown with correctness of a distance and correctness of azimuth by performing various sorts of map-projection transformation, the digital cartographic system can support an intuitive idea of a user, and also can improve an information representation function of this digital cartographic system.Type: GrantFiled: February 28, 1995Date of Patent: August 6, 1996Assignee: Hitachi, Ltd.Inventors: Takehiro Fujita, Shigeru Kakumoto, Yasuei Nomoto

Patent number: 5144679Abstract: In correspondence with the graphic data having a spatial extent, there is the address data table configured of arrays, the dimension of which are not smaller in number than the dimensions of the extent of the graphic data. Coordinate transformation is performed between the graphic data and the address data table, whereby any desired point on each figure can be brought into correspondence with one array number of the address data table. Those memory addresses of a graphic data table at which the individual graphic data items are sorted, are subsequently stored in the address data table. In case of searching for graphic data located at any desired position, the corresponding array number of the address data table is obtained on the basis of the position, whereupon the desired figure can be searched for through that memory address to the graphic data which is stored.Type: GrantFiled: February 4, 1991Date of Patent: September 1, 1992Assignees: Hitachi, Ltd, Hitachi Seiko, Ltd.Inventors: Shigeru Kakumoto, Masayasu Kato, Fumitaka Otsu, Kazuo Watanabe

Patent number: 5099520Abstract: A figure retrieval method for storing memory addresses for figure data in an address data table which corresponds to positional coordinates of a multi-dimensional array. When retrieving end points, or node points, other points on a line and points on a surface, these points constituting the figure data, memory addresses for figure data for an object to be retrieved are stored in the address data table and then retrieved. Flags indicative of the kind of the constituent points are also stored in the address data table in combination with the memory addresses and are used for figure retrieval.Type: GrantFiled: March 20, 1990Date of Patent: March 24, 1992Assignees: Hitachi Ltd., Hitachi Seiko Ltd.Inventors: Kazuaki Iwamura, Shigeru Kakumoto, Yasunori Emura

Patent number: 4991117Abstract: A figure data display method and system in which the contents to be stored and constituting data are stored in the form of figure data divided into a plurality of partial areas, a file information table is prepared which registers therein figure area information, along with volume information of the figure data, in the sequence of serial numbers allocated to the partial areas dependent on their positions, and those partial areas, which are necessary for display of the figure data, are searched within a range of the registered serial numbers. By preparing the figure data represented in the compressed form by taking relative values between the coordinate values of respective features points in the figure data, or by retrieving file names in a manner involving direct searching the figure data from a storage medium, operation from the step of reading the figure data to the step of displaying the same can be speeded up.Type: GrantFiled: December 13, 1988Date of Patent: February 5, 1991Assignees: Hitachi, Ltd., Hitachi Seiko, Ltd.Inventors: Kazuaki Iwamura, Shigeru Kakumoto, Rita M. Harder, Yasunori Emura
