The process used to correct measurement errors in surveying is calibration and adjustment. In surveying, accuracy is paramount, and measurement errors can arise from various factors, such as instrumental inaccuracies, environmental influences, or human error. Calibration involves comparing the measurements obtained with a standard or known value and adjusting them accordingly to reflect true distances or angles.

Adjustment refers to the systematic modification of measured data to minimize errors, ensuring that the results are as precise as possible. This is often done using mathematical techniques to improve the reliability and accuracy of the data collected during a survey. By using calibration and adjustment, surveyors can ensure that their measurements are consistent and meet the required standards for various applications, such as property delineation or construction projects.

In contrast, parcel evaluation relates more to the assessment of property values, surface mapping typically deals with the representation of features on a surface rather than correcting errors, and boundary realignment is focused on adjusting legal property lines rather than the initial measurement accuracy.
