<P>PROBLEM TO BE SOLVED: To provide a technology to reduce a processing load in searching data included in a prescribed range in map data. <P>SOLUTION: An information processing device comprises: map data preservation means that has a system in which an earth surface is hierarchically divided by meshes, that has geographic codes indicating the position of each mesh by a character string, and in which adding a character to the code expressing an upper mesh causes a geographic code of a lower mesh to be indicated; searching range acquisition means that acquires a searching range of the map data; mesh group processing means that selects a mesh group covering the searching range; information acquisition means that acquires a geographic code indicating a piece of positional information from a plurality of pieces of data in which pieces of positional information are set; searching means that searches data included in the mesh group covering the searching range by comparing the geographic code acquired by the information acquisition means and the geographic code in the mesh group; and output means that outputs search results obtained by the searching. <P>COPYRIGHT: (C)2013,JPO&INPIT |
