Sampling procedures are an important aspect of geophysical exploration survey design. It is good practice that the selection of survey parameters ensures that the signal to noise ratio is optimised, while minimising survey cost._x000D_
Sampling considerations for any geophysical method include the size of the target, scale of observation, aliasing associated with station and line spacing, nature and extent of overburden, and the presentation of data._x000D_
As a guide to survey design, the specifics are discussed for three geophysical techniques in common use in mineral exploration; these include the magnetic method, transient electromagnetics and induced polarisation.
