DF7929.The coordinates were established by GPS observations
DF7929.and adjusted by the National Geodetic Survey in June 2019.
DF7929
DF7929.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF7929.been affixed to the stable North American Tectonic Plate.
DF7929
DF7929.The coordinates are valid at the epoch date displayed above
DF7929.which is a decimal equivalence of Year/Month/Day.
DF7929
DF7929.Due to the release of the International GNSS Service (IGS) 2014
DF7929.realization of the International Terrestrial Reference Frame of 2014
DF7929.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF7929.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF7929.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF7929.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF7929.currently published epoch of 2010.00.
DF7929
DF7929.Additional information on MYCS2 is available at
DF7929.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF7929.Significant digits in the geoid height do not necessarily reflect accuracy.
DF7929.GEOID12B height accuracy estimate available here.

DF7929.Click photographs - Photos may exist for this station.
DF7929
DF7929.The XYZ, and position/ellipsoidal ht. are equivalent.
DF7929
DF7929.The ellipsoidal height was determined by GPS observations
DF7929.and is referenced to NAD 83.
