1. A method comprising:
automatically associating wireless seismic acquisition units to topographic locations, each wireless seismic acquisition unit comprising a satellite navigation system receiver, wherein automatically associating comprises the following steps, carried out by an associating device:
obtaining topographic locations at which respective ones of the wireless seismic acquisition units are expected to be laid, the topographic locations being defined prior to deployment of the wireless seismic acquisition units at the respective topographic locations and stored in a topographic location file on at least one non-transitory computer-readable medium;
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;
computing associations, each association between one of the wireless seismic acquisition units and a respective one of the topographic locations, said associations based on a function of a comparison between the measured positions of said wireless seismic acquisition units and the topographic locations at which respective ones of the wireless seismic acquisition units are expected to be laid using at least one predetermined rule of association, where, for each seismic acquisition unit, if said wireless seismic acquisition unit meets said at least one predetermined rule of association, said seismic acquisition unit is associated with its respective one of the topographic locations,
wherein said at least one predetermined rule includes the following first rule: a given topographic location is associated to the closest wireless seismic acquisition unit, provided that a distance between said given topographic location and a measured position of said closest wireless seismic acquisition unit is less than an association distance,
outputting the associations for each wireless seismic acquisition unit and their respective one of the topographic locations to a database stored on the at least one non-transitory computer-readable medium; and
wherein the method further comprises generating a display on a man-machine interface based on the outputted associations.
