A geodetic control network is a network, often of triangles, that are measured precisely by techniques of control surveying, such as terrestrial surveying or satellite geodesy. It is also known as a geodetic network , reference network , control point network , or simply control network .
Dimensional control survey: This is a type of survey conducted in or on a non-level surface. Common in the oil and gas industry to replace old or damaged pipes on a like-for-like basis, the advantage of dimensional control survey is that the instrument used to conduct the survey does not need to be level.
Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point. Connected survey lines form the framework and the directions and lengths of the survey lines are measured with an angle measuring instrument and tape or chain. [2]
Some researchers have criticised control self-assessment as a flawed approach as the way risk is defined and measured is unsophisticated. In particular, control self-assessment may understate risk by not identifying extreme downside risk. An extreme downside risk is a highly improbable event that would have catastrophic consequences if it occurred.
Mobile data collection or mobile surveys is an increasingly popular method of data collection. Over 50% of surveys today are opened on mobile devices. [6] The survey, form, app or collection tool is on a mobile device such as a smart phone or a tablet.
While it is possible to use only two known control points in a resection (free stationing), it is recommended to use three control points. There is no redundancy for orientation, using two points only. [7] When performing a resection (free-stationing) on more than 4 points, diminishing returns are achieved in the returned results.

The Private Sector Survey on Cost Control (PSSCC), commonly referred to as the Grace Commission, was an investigation requested by United States President Ronald Reagan, authorized in Executive Order 12369 on June 30, 1982. In doing so President Reagan used the now famous phrase, "Drain the swamp". [1]
Self-control is an aspect of inhibitory control, one of the core executive functions. [ 1 ] [ 2 ] Executive functions are cognitive processes that are necessary for regulating one's behavior in order to achieve specific goals .
