摘要

This invention relates to an altitude reliability determining system comprising:
a map information acquiring unit (11) that acquires map information including road information and background information, an altitude information acquiring unit (13) that acquires altitude information indicating an altitude of each unit region, the unit region being set by dividing a map indicated in the map information into a plurality of unit regions having a predetermined size, an altitude calculating unit (14) that calculates a predicted altitude of each of a plurality of reference points based on the road information and the altitude information, the plurality of reference points being set along a road.
