Abstract:
1. A method of creating map data for representing a map for use in a map data utilization apparatus, the map made up from a plurality of map components and each of the plurality of map components having a plurality of attribute types defined in the map data, each of the attribute types is associated with at least one other attribute type from among the plurality of attribute types, the method comprising: associating, by a processor, attribute data records of a subject attribute type with attribute data records of an other attribute type by having each of the attribute data records of the other attribute type indicate a number of associated data records from the subject attribute type that respectively correspond with the attribute data record of the other attribute type; arranging, by the processor, a data list of the attribute data records for the subject attribute type based on (i) a sequential order of the attribute data records of the other attribute type such that the data list for each of the attribute types are aligned to have a same arrangement order as its associated at least one other attribute type for representing the map components of the map data, and (ii) the number of associated data records identified per each of the attribute data records of the other attribute type that respectively correspond with the attribute data record of the other attribute type such that a relationship is established between one attribute data record of the other attribute type and the corresponding attribute data records of the subject attribute type; and storing, by the processor, as the map data for representing the map for use in the map data utilization apparatus, in a form of the data list which is arranged, the attribute data records for each of the plurality of attribute types based on an association between the plurality of attribute types, wherein the attribute data records for representing each of the plurality of attribute types of each of the plurality of map components are formed as one data list.
