DL3478.The coordinates were established by GPS observations
DL3478.and adjusted by the National Geodetic Survey in June 2019.
DL3478
DL3478.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3478.been affixed to the stable North American Tectonic Plate.
DL3478
DL3478.The coordinates are valid at the epoch date displayed above
DL3478.which is a decimal equivalence of Year/Month/Day.
DL3478
DL3478.Due to the release of the International GNSS Service (IGS) 2014
DL3478.realization of the International Terrestrial Reference Frame of 2014
DL3478.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3478.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3478.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3478.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3478.currently published epoch of 2010.00.
DL3478
DL3478.Additional information on MYCS2 is available at
DL3478.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3478.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3478.GEOID18 height accuracy estimate available here.

DL3478
DL3478.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3478
DL3478.The ellipsoidal height was determined by GPS observations
DL3478.and is referenced to NAD 83.
