DP3841.The coordinates were established by GPS observations
DP3841.and adjusted by the National Geodetic Survey in June 2019.
DP3841
DP3841.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP3841.been affixed to the stable North American Tectonic Plate.
DP3841
DP3841.The coordinates are valid at the epoch date displayed above
DP3841.which is a decimal equivalence of Year/Month/Day.
DP3841
DP3841.Due to the release of the International GNSS Service (IGS) 2014
DP3841.realization of the International Terrestrial Reference Frame of 2014
DP3841.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP3841.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP3841.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP3841.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP3841.currently published epoch of 2010.00.
DP3841
DP3841.Additional information on MYCS2 is available at
DP3841.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP3841
DP3841.The XYZ, and position/ellipsoidal ht. are equivalent.
DP3841
DP3841.The ellipsoidal height was determined by GPS observations
DP3841.and is referenced to NAD 83.
