HV3450 ACCURACIES - Complete network and local accuracy information.
HV3450 DESIGNATION - TT 6 K NPS
HV3450 PID - HV3450
HV3450
HV3450 Horiz and Ellip are the horizontal and ellipsoid height accuracies
HV3450 at the 95% confidence level per Federal Geographic Data Committee
HV3450 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
HV3450 the standard deviations (one sigma) of the coordinates (NETWORK) or
HV3450 of the difference in the coordinates (LOCAL) in latitude, longitude
HV3450 and ellipsoid height. CorrNE is the (unitless) correlation
HV3450 coefficient between the latitude and longitude components of either
HV3450 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
HV3450 the three-dimensional straight-line slope distance, in km, between
HV3450 station HV3450 and the corresponding local station. Local stations
HV3450 are stations processed simultaneously in a session regardless of
HV3450 distance.

HV3450 Accuracy and standard deviation values are given in cm.
