DF4068.The coordinates were established by GPS observations
DF4068.and adjusted by the National Geodetic Survey in March 2023.
DF4068
DF4068.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF4068.been affixed to the stable North American Tectonic Plate.
DF4068
DF4068.The coordinates are valid at the epoch date displayed above
DF4068.which is a decimal equivalence of Year/Month/Day.
DF4068
DF4068.Due to the release of the International GNSS Service (IGS) 2014
DF4068.realization of the International Terrestrial Reference Frame of 2014
DF4068.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF4068.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF4068.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF4068.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF4068.currently published epoch of 2010.00.
DF4068
DF4068.Additional information on MYCS2 is available at
DF4068.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF4068
DF4068.The orthometric height was determined by GPS observations and a
DF4068.high-resolution geoid model using precise GPS observation and
DF4068.processing techniques.
DF4068
DF4068.Significant digits in the geoid height do not necessarily reflect accuracy.
DF4068.GEOID18 height accuracy estimate available here.
DF4068
DF4068.The PID for the CORS L1 Phase Center is DI8139.

DF4068.Click photographs - Photos may exist for this station.
DF4068
DF4068.The XYZ, and position/ellipsoidal ht. are equivalent.
DF4068
DF4068.The ellipsoidal height was determined by GPS observations
DF4068.and is referenced to NAD 83.
