DM7870.The coordinates were established by GPS observations
DM7870.and adjusted by the National Geodetic Survey in June 2019.
DM7870
DM7870.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7870.been affixed to the stable North American Tectonic Plate.
DM7870
DM7870.The coordinates are valid at the epoch date displayed above
DM7870.which is a decimal equivalence of Year/Month/Day.
DM7870
DM7870.Due to the release of the International GNSS Service (IGS) 2014
DM7870.realization of the International Terrestrial Reference Frame of 2014
DM7870.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7870.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7870.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7870.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7870.currently published epoch of 2010.00.
DM7870
DM7870.Additional information on MYCS2 is available at
DM7870.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM7870.Significant digits in the geoid height do not necessarily reflect accuracy.

DM7870.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7870
DM7870.The ellipsoidal height was determined by GPS observations
DM7870.and is referenced to NAD 83.
