Claim 4:
5. A relay method for a relay server that collects sensor data from a plurality of mobile terminals, each mobile terminal of the plurality of mobile terminals comprising one or more sensors, and uploads the sensor data to a central server via a network, the relay server comprising a hardware processor and a memory connected to the hardware processor, the relay method comprising:
collecting, by the relay server, the sensor data from the plurality of mobile terminals;
storing the sensor data in the memory as collected sensor data;
calculating, by the relay server, a presence of spatial overlaps between the collected sensor data stored in the memory by identifying overlaps between most temporally recent sensor data from the collected sensor data included in a spatial range to other sensor data;
removing, by the relay server in the memory, the identified overlaps between the collected sensor data;
creating, by the relay server, relay data integrating the collected sensor data without the removed overlaps;, and uploading, by the relay server, the relay data to the central server; and
with respect to the most temporally recent sensor data of the collected sensor data, calculating, by the relay server, the spatial range in which detection points included in the most temporally recent sensor data exist; determining, by the relay server, detection points of the sensor data other than the most temporally recent sensor data included in the spatial range as overlapping detection points: removing, by the relay server, sensor data of the overlapping detection points from the sensor data including the overlapping detection points; and creating, by the relay server, the relay data by integrating the most temporally recent sensor data and the sensor data from which the overlapping detection points were removed.
