AA2158 ACCURACIES - Complete network and local accuracy information.
AA2158 DESIGNATION - 2 35
AA2158 PID - AA2158
AA2158
AA2158 Horiz and Ellip are the horizontal and ellipsoid height accuracies
AA2158 at the 95% confidence level per Federal Geographic Data Committee
AA2158 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
AA2158 the standard deviations (one sigma) of the coordinates (NETWORK) or
AA2158 of the difference in the coordinates (LOCAL) in latitude, longitude
AA2158 and ellipsoid height. CorrNE is the (unitless) correlation
AA2158 coefficient between the latitude and longitude components of either
AA2158 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
AA2158 the three-dimensional straight-line slope distance, in km, between
AA2158 station AA2158 and the corresponding local station. Local stations
AA2158 are stations processed simultaneously in a session regardless of
AA2158 distance.
AA2158
AA2158 Accuracy and standard deviation values are given in cm.
