INFORMATION PROCESSING APPARATUS, CURRENT LOCATION DISPLAY SYSTEM, AREA EXTRACTION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To acquire a map that has no redundant areas and has suppressed the amount of data.SOLUTION: A server 1 includes a CPU 11-1, an area map specification processing part 52, and an area map extraction part 53. The CPU 11-1 specifies a plurality of partial areas from the entire area of data. The area map extraction part 53 extracts the plurality of partial areas specified by the CPU 11-1 as extraction areas. When there is an overlapping area in which the plurality of partial areas specified by the CPU 11-1 overlap with each other in the entire area, the area map specification processing part 52 controls the area map extraction part 53 so as not to extract the overlapping area more than once.
