摘要:
It is provided a method, comprising associating value ranges to each of a predefined number of fields, wherein the value ranges for each of the fields are continuous; associating, for each of the fields, bijectively rowkey field values to the value ranges of the respective field, wherein the rowkey field values for each of the fields are continuous; generating rowkeys, wherein each rowkey comprises one of the rowkey field values for each of the fields, and wherein a rowkey is generated for each of the corresponding combinations of the rowkey field values; wherein the associating of the rowkey field values is further adapted to associate the rowkey field values such that for each of the fields and for each of the rowkeys: a first rowkey field value for the respective field of the respective rowkey is neighbored to a second rowkey field value for the respective field of a second rowkey of the rowkeys, and a first value range of the respective field of the respective rowkey is continuous with a second value range of the respective field of the second rowkey, wherein the rowkey field values of the respective field comprise the first and second rowkey field values, and the value ranges of the respective field comprise the first and second value ranges.
摘要:
The present invention is related to detection of isolated anomalies, and operates in an automatic manner, without resulting in overloading an anomaly management system in case of large-scale anomalies occurring and that does not rely on user intervention.

An information management method to be executed by a computer, the information management method includes; accepting (S101) a registration request that includes identification information of a mobile device, and position information of the mobile device that includes latitude and longitude; generating (S111) a value that includes the identification information followed by information that indicates a date and time when the registration request is accepted; storing (S 102) the position information in a first storage unit in a manner correlated with the value; generating (S121) another value that includes the information that indicates the date and time followed by the identification information; storing (S103) the position information in a second storage unit in a manner correlated with the other value; storing (S 104) the position information in a third storage unit in a manner correlated with the identification information; and storing (S 105) the identification information in a fourth storage unit in a manner correlated with the position information.
摘要:
A system and method for providing a digital map database wherein multiple instances of geocoded objects pertaining to points of interest (POI) and/or three-dimensional (3D) objects contained within one or more building blocks are compared to find undesirable duplicate geocoded objects. Cross-referencing information is stored and preference information about which geocoded object or object property/attribute should be used is assessed to determine priority for selection or presentation on the display screen (12) of a navigation device (10) or other suitable computing device. Cross-references can be pre-calculated at compile time or calculated on-the-fly by the navigation application at run time and may be persistently stored in dedicated data structures. When duplicate geocoded objects are found, only the most accurate information or a super set of (attribute) information is used by applications or presented to a user thereby preventing confusion.

Described is a technology by which uploaded GPS data is indexed according to spatio-temporal relationships to facilitate efficient insertion and retrieval. The indexes may be converted to significantly smaller-sized data structures when new updates to that structure are not likely. GPS data is processed into a track of spatially-partitioned segments such that each segment has a cell. Each cell has an associated temporal index (a compressed start-end tree), into which data for that cell's segments are inserted. The temporal index may include an end time index that relates each segment's end time to a matching start time index. Given query input comprising a spatial predicate and a temporal predicate, tracks may be searched for by determining which spatial candidate cells may contain matching results. For each candidate cell, the search accesses the cell's associated temporal index to find any track or tracks that correspond to the temporal predicate.
