Stakeouts play a major role in construction surveying. This involves the transfer and marking of previously planned dimensions and geometric points on a site or property. Stakeouts are used in a wide range of applications from a metrological point of view. For example, modern machinery and hall layouts are precisely staked out before assembly begins, but stage set concepts are also marked out by staking out before final assembly. For the precise staking out of areas, optical measurement techniques are usually used, such as tachymetry for polar staking out.
