Forensic geophysics put the pieces together

摘要

One processing shop goes to great lengths to find vintage data - and reprocesses it with tender loving care. On page 54 of this issue you will find a feature on seismic data processing. Processing has really taken off in the past few years, aided by faster compute power and technology transfer from other industries such as gaming. But the basic adage behind processing has always been "garbage in, garbage out" (or any number of variations of the word "garbage"). In other words, if raw data is of poor quality, there is not much that even the cleverest processor can do to render the final product useful.
