DL2744.The coordinates were established by GPS observations
DL2744.and adjusted by the National Geodetic Survey in August 2024.
DL2744
DL2744.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2744.been affixed to the stable North American Tectonic Plate.
DL2744
DL2744.The coordinates are valid at the epoch date displayed above
DL2744.which is a decimal equivalence of Year/Month/Day.
DL2744
DL2744.Due to the release of the International GNSS Service (IGS) 2014
DL2744.realization of the International Terrestrial Reference Frame of 2014
DL2744.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2744.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2744.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2744.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2744.currently published epoch of 2010.00.
DL2744
DL2744.Additional information on MYCS2 is available at
DL2744.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL2744.Significant digits in the geoid height do not necessarily reflect accuracy.
DL2744.GEOID18 height accuracy estimate available here.

DL2744.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2744
DL2744.The ellipsoidal height was determined by GPS observations
DL2744.and is referenced to NAD 83.
