DH3753.The coordinates were established by GPS observations
DH3753.and adjusted by the National Geodetic Survey in June 2019.
DH3753
DH3753.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3753.been affixed to the stable North American Tectonic Plate.
DH3753
DH3753.The coordinates are valid at the epoch date displayed above
DH3753.which is a decimal equivalence of Year/Month/Day.
DH3753
DH3753.Due to the release of the International GNSS Service (IGS) 2014
DH3753.realization of the International Terrestrial Reference Frame of 2014
DH3753.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3753.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3753.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3753.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3753.currently published epoch of 2010.00.
DH3753
DH3753.Additional information on MYCS2 is available at
DH3753.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH3753
DH3753.The orthometric height was determined by GPS observations and a
DH3753.high-resolution geoid model using precise GPS observation and
DH3753.processing techniques.
DH3753
DH3753.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3753.GEOID18 height accuracy estimate available here.
DH3753
DH3753.The PID for the CORS L1 Phase Center is DI3730.

DH3753
DH3753.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3753
DH3753.The ellipsoidal height was determined by GPS observations
DH3753.and is referenced to NAD 83.
