GX1681 ACCURACIES - Complete network and local accuracy information.
GX1681 CBN - This is a Cooperative Base Network Control Station.
GX1681 DESIGNATION - C 195
GX1681 PID - GX1681
GX1681
GX1681 Horiz and Ellip are the horizontal and ellipsoid height accuracies
GX1681 at the 95% confidence level per Federal Geographic Data Committee
GX1681 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
GX1681 the standard deviations (one sigma) of the coordinates (NETWORK) or
GX1681 of the difference in the coordinates (LOCAL) in latitude, longitude
GX1681 and ellipsoid height. CorrNE is the (unitless) correlation
GX1681 coefficient between the latitude and longitude components of either
GX1681 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
GX1681 the three-dimensional straight-line slope distance, in km, between
GX1681 station GX1681 and the corresponding local station. Local stations
GX1681 are stations processed simultaneously in a session regardless of
GX1681 distance.
GX1681
GX1681 Accuracy and standard deviation values are given in cm.
