Abstract
A map information update support device includes a communication interface unit that acquires plural items of radar image data of the same observation area acquired at different times, respectively, a registration processing unit that registrates the plural items of radar image data with respect to one another, a characteristic value calculation unit that calculates a characteristic value representing a state of a surface of the earth in the observation area using the items of radar image data after the registration process, a feature changed area extraction unit that extracts a feature changed area based on the characteristic value, a road change candidate area extraction unit that synthesizes the feature changed area with map information of the observation area and extracts a road change candidate area that is a candidate of a road changed portion, and an output unit that outputs the map information synthesized with the road change candidate area.
