 DI3431.The coordinates were established by GPS observations
 DI3431.and adjusted by the National Geodetic Survey in June 2019.
 DI3431
 DI3431.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DI3431.been affixed to the stable North American Tectonic Plate. 
 DI3431
 DI3431.The coordinates are valid at the epoch date displayed above
 DI3431.which is a decimal equivalence of Year/Month/Day.
 DI3431
 DI3431.Due to the release of the International GNSS Service (IGS) 2014
 DI3431.realization of the International Terrestrial Reference Frame of 2014
 DI3431.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
 DI3431.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
 DI3431.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
 DI3431.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
 DI3431.currently published epoch of 2010.00.
 DI3431
 DI3431.Additional information on MYCS2 is available at
 DI3431.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
 DI3431
 DI3431.The orthometric height was determined by GPS observations and a
 DI3431.high-resolution geoid model using precise GPS observation and
 DI3431.processing techniques.
 DI3431
 DI3431.Significant digits in the geoid height do not necessarily reflect accuracy.
 DI3431.GEOID18 height accuracy estimate available here.
 DI3431
 DI3431.The PID for the CORS L1 Phase Center is DL3083.

 DI3431.Click photographs - Photos may exist for this station.
 DI3431
 DI3431.The XYZ, and position/ellipsoidal ht. are equivalent.
 DI3431
 DI3431.The ellipsoidal height was determined by GPS observations
 DI3431.and is referenced to NAD 83.
