Rigorous Estimation of Local Accuracies
This technical note introduces a rigorous calculation of “local accuracies.” The term local accuracies refers to the relative error between 2 arbitrary points (uncertainty of one point with respect to the other), expressed in a local horizon 3-D reference frame (e,n,u), that were connected using any geodetic-surveying methodology [optical procedures, global positioning system (GPS), etc.]. It is calculated as a function of the full global Cartesian variance-covariance matrix of the (x,y,z) coordinates of the points defining the spatial network.
