An apparatus and method for collecting data acquired during a seismic survey are disclosed. The apparatus is a seismic survey system, comprising a plurality of data sources, a plurality of cells, and a plurality of independent pathways. The data sources are positioned about an area to be surveyed, each data source being associated with a transmitter capable of transmitting data. The cells each contain a portion of the data sources and their associated transmitters. One of the transmitters within each cell also serves as a gateway for receiving data transmitted from the other data source transmitters within the cell. The independent pathways each contain a portion of the gateways whereby data may be transmitted along each pathway via the gateways and associated transmitters in that pathway. The method is a method for conducting a seismic survey. The method comprises positioning a plurality of seismic data sources about an area to be surveyed; defining a plurality of cells such that each cell contains a portion of the seismic data sources; defining one of the seismic data sources within each cell to also serve as a gateway; defining a plurality of independent pathways such that each pathway contains a portion of the gateways; within each respective cell, transmitting seismic data from the seismic data sources to the gateway; and, within each pathway, transmitting the seismic data from one gateway to another to reach a central location.

The invention claimed is: 1. A seismic survey system, comprising: a plurality of transmitters; a plurality of data sources positioned about an area to be surveyed, each data source, when in operation, communicating with one of the transmitters that, when in operation, transmits data from the data sources; a plurality of cells each containing a portion of the data sources and the transmitters with which they communicate, one of the transmitters within each cell also serving as a gateway during operation for receiving data transmitted from the other data source transmitters within the cell and transmitting the data collected within the cell; and a plurality of independent pathways, each independent pathway containing a least one gateway through which data is transmitted during operation along each pathway via at least one gateway in that pathway without consolidation of data. 2. The seismic survey system of claim 1, further wherein the transmitter comprise transmitters that, in operation, wirelessly transmits data. 3. The seismic survey system of claim 1, further comprising a computing and storing center for receiving the data transmitted along each pathway. 4. The seismic survey system of claim 3, further comprising at least a pair of relay points through which the data transmitted along each independent pathway is relayed to the computing and storing center. 5. The seismic survey system of claim 1, further comprising a fixed-base facility to which the data is transmitted. 6. The seismic survey system of claim 5, further comprising a recording truck through which the data is transmitted to the fixed-base facility. 7. The seismic survey system of claim 1, wherein the transmitters comprise transmitters that, in operation, transmit data in an asynchronous mode. 8. The seismic survey system of claim 1, wherein the transmitters comprise transmitters that, in operation, transmit data in a synchronous mode. 9. The seismic survey system of claim 1, wherein the data is transmitted along each independent pathway according to frequency division multiplexing. 10. The seismic survey system of claim 1, wherein the data is transmitted along each pathway according to time division multiplexing. 11. The seismic survey system of claim 1, wherein the distance between gateways of adjacent cells is limited according to transmission licensing constraints. 12. The seismic survey system of claim 1, wherein the distance between gateways of adjacent cells is limited to improve reliability. 13. The seismic survey system of claim 1, wherein the pathways are substantially linear. 14. The seismic survey system of claim 1, wherein the cells overlap. 15. The seismic survey system of claim 1, wherein the cells are interleaved. 16. A seismic survey system of claim 1, wherein no gateway in a path directly receives data from more than one gateway or directly transmits data to more than one gateway. 17. The seismic survey system of claim 1, wherein at least one cell is arranged to, in addition to transmitting date from data source in the cell, relay, in use, data received from a gateway of another cell. 18. A method for use in seismic surveying, comprising: collecting a plurality of seismic data at a plurality of seismic data sources, each data sources communicating with a transmitter that, in operation, transmits data, the seismic data sources being organized into a plurality of cells, one of the transmitters within each cell also serving as a gateway for receiving data transmitted from the other data source transmitters within the cell; transmitting the collected seismic data over a plurality of independent pathways to a central location, each independent pathway containing at least one gateway through which data is transmitted during operation along each pathway via the at least one gateway without consolidation of data; and collecting the transmitted seismic data at the central location. 19. The method of claim 18, wherein transmitting the collected seismic data includes transmitting the collected seismic data using one of frequency division multiplexing and time division multiplexing. 20. The method of claim 18, wherein the cell definitions are constrained with transmission licensing constraints. 21. The method of claim 18, wherein the distance between cells is constrained to improve reliability. 22. The method of claim 18, wherein the cells overlap. 23. The method of claim 18, wherein cells are interleaved. 24. The method of claim 18, wherein defining the independent pathways include at least a pair of relay points through which the collected seismic data is transmitted to the central location. 25. The method of claim 18, wherein no gateway in a path directly receives data from more than one gateway or directly transmits data to more than one gateway.
