DF5771.The coordinates were established by GPS observations
DF5771.and adjusted by the National Geodetic Survey in June 2019.
DF5771
DF5771.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF5771.been affixed to the stable North American Tectonic Plate.
DF5771
DF5771.The coordinates are valid at the epoch date displayed above
DF5771.which is a decimal equivalence of Year/Month/Day.
DF5771
DF5771.Due to the release of the International GNSS Service (IGS) 2014
DF5771.realization of the International Terrestrial Reference Frame of 2014
DF5771.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF5771.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF5771.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF5771.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF5771.currently published epoch of 2010.00.
DF5771
DF5771.Additional information on MYCS2 is available at
DF5771.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF5771.** This station is in an area of known vertical motion. Due to the
DF5771.** variability of land subsidence, uplift, and crustal motion, NGS has,
DF5771.** determined the orthometric heights for marks in these suspect
DF5771.** subsidence areas should be considered valid only at the epoch date
DF5771.** associated with the orthometric height. These heights must always
DF5771.** be validated when used as control. All previously superseded
DF5771.** orthometric heights are now considered suspect and are available
DF5771.** in the superseded section. NGS does not recommend using suspect
DF5771.** or superseded heights as control.
DF5771
DF5771.The orthometric height was determined by GPS observations and a
DF5771.high-resolution geoid model using precise GPS observation and
DF5771.processing techniques.
DF5771
DF5771.Significant digits in the geoid height do not necessarily reflect accuracy.
DF5771.GEOID18 height accuracy estimate available here.
DF5771
DF5771.The PID for the CORS L1 Phase Center is DR1465.

DF5771.Click photographs - Photos may exist for this station.
DF5771
DF5771.The XYZ, and position/ellipsoidal ht. are equivalent.
DF5771
DF5771.The ellipsoidal height was determined by GPS observations
DF5771.and is referenced to NAD 83.
