Abstract: An information processing system, comprises a data acquirer that acquires an image captured by a vehicle-mounted camera included in a first vehicle, and positional information of the first vehicle; an analyzer that analyzes a road condition in a periphery of the first vehicle based on one or more images that have been acquired; and an evaluator that assigns a cost value to a spot or a road link included in map data based on a result of analyzing the road condition and positional information corresponding to the image.
