METODO E APPARECCHIATURA ASSOCIATI AD UN SISTEMA A MICROCALCOLATORE PER L'INDICAZIONE E REGISTRAZIONE AUTOMATICA DEI PARAMETRI CHE DEFINISCONO SPAZIALMENTE LE COLLOCAZIONI DELLE AREE DI ESPLORAZIONE SISMICA E DEGLI SCHIERAMENTI DI SORGENTI DI TALI PARAMETRI

In seismic exploration there is provided in association with a microcomputer system a method and apparatus for (i) selectively providing an alarm-generating digital code so as to alert an operator that the next-in- time positions of a source-detector array are the last approved locations before the recording truck location must be changed; (ii) providing a next- in-time positional code for disconnectably connecting recording circuitry to different but contiguous sets of detectors, i.e. an "active" array, from among a plurality of detectors positioned along the line of survey; and (iii) for conditionally updating source-detector array parameters related to a seismic exploration system, especially during generation and collection of seismic data using a vibratory source detector array positioned at known locations along a line of survey at the earth's surface.
