Absolutely accuracy refers to how accurate a survey measurement is - within a specific coordinate system. For example, a determined boundary survey for Land Registry should have an absolute accuracy within Ordnance Survey National Grid of 300 mm (0.3 metres)

Most surveys will incorporate some control, but a control survey is only concerned with establishing a robust and well referenced control network for other survey works to be carried out from. Recommended as a first step for larger sites and areas, this ensures an adequate framework is installed before hundreds of hours are invested in carrying out detail survey works (mapping the features).

The hedge and ditch rule implies that where a hedge lies between land and a ditch, the ditch also belongs to the owner of the land. The underlying premise is that the current (or a previous) landowner dug the ditch immediately adjacent to the boundary line and planted a hedge on the excavated soil deposited within their own parcel. This is a simplified example and many other factors may come into play in determining if this rule can apply.

Local scale factor is a multiplier that is applied to survey measurements on some surveys, to respect the curvature of the earth, within the projection/coordinate system/grid being used.
