AH8407 PID - AH8407
AH8407
AH8407 Horiz and Ellip are the horizontal and ellipsoid height accuracies
AH8407 at the 95% confidence level per Federal Geographic Data Committee
AH8407 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
AH8407 the standard deviations (one sigma) of the coordinates (NETWORK) or
AH8407 of the difference in the coordinates (LOCAL) in latitude, longitude
AH8407 and ellipsoid height. CorrNE is the (unitless) correlation
AH8407 coefficient between the latitude and longitude components of either
AH8407 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
AH8407 the three-dimensional straight-line slope distance, in km, between
AH8407 station AH8407 and the corresponding local station. Local stations
AH8407 are stations processed simultaneously in a session regardless of
AH8407 distance.
AH8407
AH8407 Accuracy and standard deviation values are given in cm.
