DF4371.The coordinates were established by GPS observations
DF4371.and adjusted by the National Geodetic Survey in June 2019.
DF4371
DF4371.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF4371.been affixed to the stable North American Tectonic Plate.
DF4371
DF4371.The coordinates are valid at the epoch date displayed above
DF4371.which is a decimal equivalence of Year/Month/Day.
DF4371
DF4371.Due to the release of the International GNSS Service (IGS) 2014
DF4371.realization of the International Terrestrial Reference Frame of 2014
DF4371.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF4371.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF4371.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF4371.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF4371.currently published epoch of 2010.00.
DF4371
DF4371.Additional information on MYCS2 is available at
DF4371.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF4371.Significant digits in the geoid height do not necessarily reflect accuracy.
DF4371.GEOID18 height accuracy estimate available here.

DF4371.The XYZ, and position/ellipsoidal ht. are equivalent.
DF4371
DF4371.The ellipsoidal height was determined by GPS observations
DF4371.and is referenced to NAD 83.
