In the aggregation of probe data, aggregation using fine spatial granularity is enabled and high-precision aggregation can be performed by controlling the loss of the information content of the probe data. A data recording unit (121) records probe data generated by a vehicle, which is a probe (101). In a filter coefficient recording unit (125), a filter coefficient determined according to the distance between a road, which is a geographical element existing within a geographical range divided into a plurality of regions, and each of the plurality of regions is recorded in association with each of the plurality of regions. In a filter calculation processing unit (126), a region corresponding to the probe data recorded by the data recording unit (121) from among the plurality of regions is selected, the filter coefficient associated with the region and recorded by the filter coefficient recording unit (125) is read for each selected region, and the probe data is weighed and aggregated using the filter coefficient.
