PROBLEM TO BE SOLVED: To provide an observation apparatus that can be integrated into the infrastructure of an existing observation network and does not need to construct another observation network.SOLUTION: A GPS receiver 2 including a GPS antenna 3 and a barometer 4 are arranged in the same observation post. Positional data D1 and barometric pressure data D4 output by each device are once gathered at a data gathering device 5, and the data gathering device 5, as a representative of the devices, transmits the positional data D1 and the barometric pressure data D4 to a central device 100 via a communication network 10. |
