DM2704.The coordinates were established by GPS observations
DM2704.and adjusted by the National Geodetic Survey in June 2019.
DM2704
DM2704.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2704.been affixed to the stable North American Tectonic Plate.
DM2704
DM2704.The coordinates are valid at the epoch date displayed above
DM2704.which is a decimal equivalence of Year/Month/Day.
DM2704
DM2704.Due to the release of the International GNSS Service (IGS) 2014
DM2704.realization of the International Terrestrial Reference Frame of 2014
DM2704.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2704.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2704.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2704.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2704.currently published epoch of 2010.00.
DM2704
DM2704.Additional information on MYCS2 is available at
DM2704.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM2704.Significant digits in the geoid height do not necessarily reflect accuracy.
DM2704.GEOID18 height accuracy estimate available here.

DM2704.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2704
DM2704.The ellipsoidal height was determined by GPS observations
DM2704.and is referenced to NAD 83.
