It is proposed a method for automatically assigning wireless seismic acquisition units to topographic positions, each wireless seismic acquisition unit includes a satellite navigation system receiver. The method has the following steps, carried out by an assigning device: obtaining topographic locations at which the wireless seismic acquisition units are expected to be laid; obtaining measured positions of the wireless seismic acquisition units, corresponding to or derived from position information provided by the satellite navigation system receivers when the wireless seismic acquisition units are installed on the ground, each near one of the topographic locations; and computing associations, each between one of the wireless seismic acquisition units and one of the topographic positions, as a function of a comparison between the measured positions and the topographic locations.

A data acquisition network includes an assembly of nodes including at least one wireless network of nodes in which two neighboring nodes transmit data between each other by radio waves. The assembly of nodes also includes at least one other network of nodes in which two neighboring nodes transmit data between each other by a cable. The data is also conveyed by radio waves. The at least one other network forms a cabled network of nodes.
