DI1690.The coordinates were established by GPS observations
DI1690.and adjusted by the National Geodetic Survey in June 2019.
DI1690
DI1690.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1690.been affixed to the stable North American Tectonic Plate.
DI1690
DI1690.The coordinates are valid at the epoch date displayed above
DI1690.which is a decimal equivalence of Year/Month/Day.
DI1690
DI1690.Due to the release of the International GNSS Service (IGS) 2014
DI1690.realization of the International Terrestrial Reference Frame of 2014
DI1690.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1690.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1690.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1690.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1690.currently published epoch of 2010.00.
DI1690
DI1690.Additional information on MYCS2 is available at
DI1690.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI1690
DI1690.The orthometric height was determined by GPS observations and a
DI1690.high-resolution geoid model using precise GPS observation and
DI1690.processing techniques.
DI1690
DI1690.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1690.GEOID18 height accuracy estimate available here.
DI1690
DI1690.The PID for the CORS L1 Phase Center is DL3081.

DI1690.Click photographs - Photos may exist for this station.
DI1690
DI1690.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1690
DI1690.The ellipsoidal height was determined by GPS observations
DI1690.and is referenced to NAD 83.
