The horizontal coordinates were established by GPS observations
and adjusted by the National Geodetic Survey in June 2012.
NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
been affixed to the stable North American tectonic plate. See
NA2011 for more information.
The horizontal coordinates are valid at the epoch date displayed above
which is a decimal equivalence of Year/Month/Day.
The orthometric height was determined by GPS observations and a
high-resolution geoid model using precise GPS observation and
processing techniques.
Significant digits in the geoid height do not necessarily reflect accuracy.
GEOID12B height accuracy estimate available here.
Photographs are available for this station.
The X, Y, and Z were computed from the position and the ellipsoidal ht.
The Laplace correction was computed from DEFLEC12B derived deflections.
The ellipsoidal height was determined by GPS observations
and is referenced to NAD 83.
The following values were computed from the NAD 83(2011) position.
