Patent number: 6983205Abstract: Provides methods, apparatus and system for compressing a large number of continuous location data of moving objects. A large number of continuous location data of moving objects sent from a mobile unit or a locating device are received, these location data are compressed and inserted the compressed location data into a database, so as to solve the problem that the data can not work under a high insertion frequency, and reduce the storage space of continuous locations while maintaining certain location query precision. An example apparatus for compressing the location data of moving objects, comprises: input interface for receiving current location data of a moving continuously; data compressing unit for compressing the location data received via said input interface; and output interface for outputting compressed location data of the moving object.Type: GrantFiled: December 5, 2003Date of Patent: January 3, 2006Assignee: International Business Machines CorporationInventors: Ying Chen, Fang Yan Rao, Xiu Lan Yu

Patent number: 6940530Abstract: Provides point label placement determining methods, apparatus and systems. A point label placement determining method and system are used in map browsing service based on session mode. In an example embodiment, initial label placement data in a scale is calculated by a static point label determining method. When a user requires a map browsing service, the requirement are met by using an incremental label placement method on the base of said initial label placement data. The incremental point label placement method dramatically reduces the cost for service process. Therefore, the simultaneous requirements of a large number of users can be met. The present invention is successfully used in location based service systems.Type: GrantFiled: May 20, 2003Date of Patent: September 6, 2005Assignee: International Business Machines CorporationInventors: Ying Chen, Xiu Lan Yu, Fang Yan Rao
