Abstract

A method, apparatus and system for acquiring seismic data is disclosed that in one aspect receives a seismic signal detected by at least one sensor in response to a seismic energy signal generated by a source at a selected location at a data acquisition unit in data that is in data communication with the sensor, receives at least one parameter of the source and/or receiver at the data acquisition unit; and generates a data block at the data acquisition unit having data representative of the received seismic signal and a header that contains data representative of the at least one parameter of the source and/or receiver. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
