SG0028 ACCURACIES - Complete network and local accuracy information.
SG0028 CBN - This is a Cooperative Base Network Control Station.
SG0028 DESIGNATION - V 65
SG0028 PID - SG0028
SG0028
SG0028 Horiz and Ellip are the horizontal and ellipsoid height accuracies
SG0028 at the 95% confidence level per Federal Geographic Data Committee
SG0028 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
SG0028 the standard deviations (one sigma) of the coordinates (NETWORK) or
SG0028 of the difference in the coordinates (LOCAL) in latitude, longitude
SG0028 and ellipsoid height. CorrNE is the (unitless) correlation
SG0028 coefficient between the latitude and longitude components of either
SG0028 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
SG0028 the three-dimensional straight-line slope distance, in km, between
SG0028 station SG0028 and the corresponding local station. Local stations
SG0028 are stations processed simultaneously in a session regardless of
SG0028 distance.
SG0028
SG0028 Accuracy and standard deviation values are given in cm.
