The pieces of attribute information in the attribute information data list are arranged in the order corresponding to the pieces of geometric information or phase information which are feature information, and the pieces of relation information are arranged in the order corresponding to the pieces of geometric information or phase information which are feature information.

Navigation device and navigation method

The present invention aims to provide a technology capable of enhancing the effect of reducing differential data in size. A bit shift unit shifts either of old data and new data in a forward direction and a backward direction of its bit string by each of 0, 1, 2, . . . , and n bit(s) to generate a plurality of data. A copy bit string extracting unit extracts information on copy bit strings based on the plurality of data and other non-shifted data. An additional bit string extracting unit excludes copy bit strings from the new data to extract information on additional bit strings. A differential data generating unit creates differential data based on the information on copy bit strings and the information on additional bit strings.
