DP4775.The coordinates were established by GPS observations
DP4775.and adjusted by the National Geodetic Survey in June 2019.
DP4775
DP4775.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP4775.been affixed to the stable North American Tectonic Plate.
DP4775
DP4775.The coordinates are valid at the epoch date displayed above
DP4775.which is a decimal equivalence of Year/Month/Day.
DP4775
DP4775.Due to the release of the International GNSS Service (IGS) 2014
DP4775.realization of the International Terrestrial Reference Frame of 2014
DP4775.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP4775.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP4775.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP4775.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP4775.currently published epoch of 2010.00.
DP4775
DP4775.Additional information on MYCS2 is available at
DP4775.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP4775.Significant digits in the geoid height do not necessarily reflect accuracy.
DP4775.GEOID18 height accuracy estimate available here.

DP4775.Click photographs - Photos may exist for this station.
DP4775
DP4775.The XYZ, and position/ellipsoidal ht. are equivalent.
DP4775
DP4775.The ellipsoidal height was determined by GPS observations
DP4775.and is referenced to NAD 83.
