Information providing apparatus and system

Abstract

An information providing apparatus including a microprocessor and a memory storing a map information including a road map. The microprocessor is configured to perform: acquiring from an in-vehicle device, driving information including position information indicating the position of a vehicle detected by a first sensor and measurement error information indicating an occurrence of a measurement error output by a second sensor measuring an external environment of the vehicle, and further acquiring the map information from the memory; determining whether a snowfall has occurred in a predetermined region of the road map, based on the driving information and the map information; and outputting information in which a determination result is associated with the road map. The determining includes when recognizing that the measurement error has occurred while the vehicle is traveling in the predetermined region, determining that the snowfall has occurred in the predetermined region.
