...R. F. Blakely; C. R. Ellis; H. J. Martin abstract A semi-automatic system to digitize seismographic records is described. Photographic images of the records are digitized using a cathode-ray-tube film scanner that is controlled by a computer. An operator, interacting with the computer through...

... seismograph with a maximum capacity of 1024 channels and sign bit recording technology. Vibrators were the source of energy. Simple four-line swath geometry with 192 live channels (4 × 48 channels) was used with a bin size of 15 × 60 m. The data were processed by GSI Singapore in 1988 because no in-house...
