DF5878.The coordinates were established by GPS observations
DF5878.and adjusted by the National Geodetic Survey in June 2019.
DF5878
DF5878.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF5878.been affixed to the stable North American Tectonic Plate.
DF5878
DF5878.The coordinates are valid at the epoch date displayed above
DF5878.which is a decimal equivalence of Year/Month/Day.
DF5878
DF5878.Due to the release of the International GNSS Service (IGS) 2014
DF5878.realization of the International Terrestrial Reference Frame of 2014
DF5878.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF5878.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF5878.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF5878.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF5878.currently published epoch of 2010.00.
DF5878
DF5878.Additional information on MYCS2 is available at
DF5878.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF5878.Significant digits in the geoid height do not necessarily reflect accuracy.
DF5878.GEOID18 height accuracy estimate available here.

DF5878.Click photographs - Photos may exist for this station.
DF5878
DF5878.The XYZ, and position/ellipsoidal ht. are equivalent.
DF5878
DF5878.The ellipsoidal height was determined by GPS observations
DF5878.and is referenced to NAD 83.
