DP3850.The coordinates were established by GPS observations
DP3850.and adjusted by the National Geodetic Survey in June 2019.
DP3850
DP3850.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP3850.been affixed to the stable North American Tectonic Plate.
DP3850
DP3850.The coordinates are valid at the epoch date displayed above
DP3850.which is a decimal equivalence of Year/Month/Day.
DP3850
DP3850.Due to the release of the International GNSS Service (IGS) 2014
DP3850.realization of the International Terrestrial Reference Frame of 2014
DP3850.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP3850.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP3850.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP3850.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP3850.currently published epoch of 2010.00.
DP3850
DP3850.Additional information on MYCS2 is available at
DP3850.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP3850
DP3850.The XYZ, and position/ellipsoidal ht. are equivalent.
DP3850
DP3850.The ellipsoidal height was determined by GPS observations
DP3850.and is referenced to NAD 83.
