摘要
The invention relates to a network of communicating survey nails (10) that each comprise an active radio-frequency identification beacon, comprising: - a stand-alone electrical power source for powering a transmitter and a storing means; - the storing means storing a unique identifier and information on the position of the nail; - the transmitter transmitting, using an RFID protocol, a radiofrequency signal containing said unique identifier and said information on the position of the nail, the transmitter comprising an antenna. The invention also relates to a device (30) for recording topography, which comprises at least three nails (10) and a geo-referencing device (36) comprising: - a first means (361) for communicating using an RFID protocol, for receiving the radiofrequency signal containing the unique identifier and the position information of each nail; and - a triangulating means (363) configured to compute the position of the geo-referencing device with respect to the position of the three nails.
