DH7125.The coordinates were established by GPS observations
DH7125.and adjusted by the National Geodetic Survey in June 2020.
DH7125
DH7125.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7125.been affixed to the stable North American Tectonic Plate.
DH7125
DH7125.The coordinates are valid at the epoch date displayed above
DH7125.which is a decimal equivalence of Year/Month/Day.
DH7125
DH7125.Due to the release of the International GNSS Service (IGS) 2014
DH7125.realization of the International Terrestrial Reference Frame of 2014
DH7125.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7125.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7125.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7125.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7125.currently published epoch of 2010.00.
DH7125
DH7125.Additional information on MYCS2 is available at
DH7125.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH7125
DH7125.The orthometric height was determined by GPS observations and a
DH7125.high-resolution geoid model using precise GPS observation and
DH7125.processing techniques.
DH7125
DH7125.Significant digits in the geoid height do not necessarily reflect accuracy.
DH7125.GEOID18 height accuracy estimate available here.

DH7125
DH7125.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7125
DH7125.The ellipsoidal height was determined by GPS observations
DH7125.and is referenced to NAD 83.
