Abstract
A seismic data acquisition system includes a controller, a plurality of sensor stations and a plurality of seismic sources. Each sensor station includes a sensor coupled to the earth for sensing seismic energy in the earth. The sensor provides a signal indicative of the sensed seismic energy and a recorder device co-located with the sensor unit that receives and stores the signals. A communication device is co-located with the sensor station and provides direct two-way wireless communication with the central controller. In one embodiment, in-field personnel determine elevation values, or Z values, for the sensor stations and seismic source by accessing a digital elevation model or a look-up table based on the digital elevation model. 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.
