DP1957.The coordinates were established by GPS observations
DP1957.and adjusted by the National Geodetic Survey in June 2019.
DP1957
DP1957.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP1957.been affixed to the stable North American Tectonic Plate.
DP1957
DP1957.The coordinates are valid at the epoch date displayed above
DP1957.which is a decimal equivalence of Year/Month/Day.
DP1957
DP1957.Due to the release of the International GNSS Service (IGS) 2014
DP1957.realization of the International Terrestrial Reference Frame of 2014
DP1957.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP1957.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP1957.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP1957.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP1957.currently published epoch of 2010.00.
DP1957
DP1957.Additional information on MYCS2 is available at
DP1957.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP1957.Significant digits in the geoid height do not necessarily reflect accuracy.

DP1957.The XYZ, and position/ellipsoidal ht. are equivalent.
DP1957
DP1957.The ellipsoidal height was determined by GPS observations
DP1957.and is referenced to NAD 83.
