DP3844.The coordinates were established by GPS observations
DP3844.and adjusted by the National Geodetic Survey in June 2019.
DP3844
DP3844.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP3844.been affixed to the stable North American Tectonic Plate.
DP3844
DP3844.The coordinates are valid at the epoch date displayed above
DP3844.which is a decimal equivalence of Year/Month/Day.
DP3844
DP3844.Due to the release of the International GNSS Service (IGS) 2014
DP3844.realization of the International Terrestrial Reference Frame of 2014
DP3844.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP3844.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP3844.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP3844.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP3844.currently published epoch of 2010.00.
DP3844
DP3844.Additional information on MYCS2 is available at
DP3844.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP3844.The XYZ, and position/ellipsoidal ht. are equivalent.
DP3844
DP3844.The ellipsoidal height was determined by GPS observations
DP3844.and is referenced to NAD 83.
