DL2037.The coordinates were established by GPS observations
DL2037.and adjusted by the National Geodetic Survey in June 2019.
DL2037
DL2037.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2037.been affixed to the stable North American Tectonic Plate.
DL2037
DL2037.The coordinates are valid at the epoch date displayed above
DL2037.which is a decimal equivalence of Year/Month/Day.
DL2037
DL2037.Due to the release of the International GNSS Service (IGS) 2014
DL2037.realization of the International Terrestrial Reference Frame of 2014
DL2037.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2037.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2037.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2037.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2037.currently published epoch of 2010.00.
DL2037
DL2037.Additional information on MYCS2 is available at
DL2037.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL2037.Significant digits in the geoid height do not necessarily reflect accuracy.
DL2037.GEOID18 height accuracy estimate available here.

DL2037.The PID for the CORS L1 Phase Center is DL2038.

DL2037.Click photographs - Photos may exist for this station.
DL2037
DL2037.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2037
DL2037.The ellipsoidal height was determined by GPS observations
DL2037.and is referenced to NAD 83.
DL2037
DL2037. The following values were computed from the NAD 83(2011) position.
