PCT No. PCT/FR91/01067 Sec. 371 Date Aug. 20, 1992 Sec. 102(e) Date Aug. 20, 1992 PCT Filed Dec. 24, 1991 PCT Pub. No. WO92/12442 PCT Pub. Date Jul. 23, 1992.A method for the automatic association, with seismic signals received by receivers (R1 . . . Rn) distributed on a site to be explored, of topographic data relative to the location of these receivers. The seismic signals are collected and stored by seismic acquisition devices (B1-Bn) which, after each seismic "shooting", transmit the signals successively to a central station 1. When the receivers are positioned in the field, each receiver is located by means of radiopositioning of the GPS type for example, and the position indications are introduced into an auxiliary memory of the corresponding acquisition device. After each repatriation of the data of a shooting, the indications are read in this memory and remain associated with those data at the time of the general grouping on the tape recorder of the central station.
