PY1050 DESIGNATION - 2 GWM
PY1050 PID - PY1050
PY1050
PY1050 Horiz and Ellip are the horizontal and ellipsoid height accuracies
PY1050 at the 95% confidence level per Federal Geographic Data Committee
PY1050 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
PY1050 the standard deviations (one sigma) of the coordinates (NETWORK) or
PY1050 of the difference in the coordinates (LOCAL) in latitude, longitude
PY1050 and ellipsoid height. CorrNE is the (unitless) correlation
PY1050 coefficient between the latitude and longitude components of either
PY1050 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
PY1050 the three-dimensional straight-line slope distance, in km, between
PY1050 station PY1050 and the corresponding local station. Local stations
PY1050 are stations processed simultaneously in a session regardless of
PY1050 distance.
PY1050
PY1050 Accuracy and standard deviation values are given in cm.
