Abstract: A map update system includes a map data storage unit storing therein map data. The map update system acquires a position of a road marking painted on a surface of a road. The map update system acquires a determination value to be subjected to determination of blurring of the road marking based on at least either of measurement information on the road marking and analysis information analyzing the measurement information. The map update system compares the determination value to a reference value and acquires blur information indicating a degree of blurring of the road marking. The map update system reflects the blur information in the map data.

Abstract: A map generation system provides to: acquire an image of the vehicle's environment from the imaging device; analyze the image to calculate the position of a feature on the road; upload map information including the position of the feature to a server; and statistically determines the coordinates of individual features in the uploaded map information.

Abstract: In a probe data evaluation apparatus, probe data are collected from a vehicle. Provisional map data are generated based on the collected probe data. The generated provisional map data are compared with reference map data, to provide a comparison result. Whether or not to adopt the collected probe data is determined based on the comparison result.
