DP1231.The coordinates were established by GPS observations
DP1231.and adjusted by the National Geodetic Survey in April 2020.
DP1231
DP1231.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP1231.been affixed to the stable North American Tectonic Plate.
DP1231
DP1231.The coordinates are valid at the epoch date displayed above
DP1231.which is a decimal equivalence of Year/Month/Day.
DP1231
DP1231.Due to the release of the International GNSS Service (IGS) 2014
DP1231.realization of the International Terrestrial Reference Frame of 2014
DP1231.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP1231.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP1231.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP1231.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP1231.currently published epoch of 2010.00.
DP1231
DP1231.Additional information on MYCS2 is available at
DP1231.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP1231.Significant digits in the geoid height do not necessarily reflect accuracy.
DP1231.GEOID18 height accuracy estimate available here.

DP1231
DP1231.The XYZ, and position/ellipsoidal ht. are equivalent.
DP1231
DP1231.The ellipsoidal height was determined by GPS observations
DP1231.and is referenced to NAD 83.
