An Adjustment is a mathematical process of generating corrections to Reduced Observations and Coordinates to generate a consistent set of adjusted Coordinates and adjusted Reduced Observations. The adjusted Reduced Observations are able to be re-generated from the adjusted Coordinates and are therefore not retained. Inputs are, Reduced Observations, Observation Accuracy, Coordinates and constraints which are defined by Adjustment Method and Adjustment Coefficients. The primary outputs are adjusted Coordinates, Coordinate Accuracy (again in the form of a VCV matrix) and identification of suspect Reduced Observations.The Adjustment entity contains information about the network adjustment process including, the type of adjustment model used, constraints applied, source, etc.
