AI4198.The coordinates were established by GPS observations
AI4198.and adjusted by the National Geodetic Survey in June 2019.
AI4198
AI4198.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI4198.been affixed to the stable North American Tectonic Plate.
AI4198
AI4198.The coordinates are valid at the epoch date displayed above
AI4198.which is a decimal equivalence of Year/Month/Day.
AI4198
AI4198.Due to the release of the International GNSS Service (IGS) 2014
AI4198.realization of the International Terrestrial Reference Frame of 2014
AI4198.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI4198.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI4198.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI4198.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI4198.currently published epoch of 2010.00.
AI4198
AI4198.Additional information on MYCS2 is available at
AI4198.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI4198
AI4198.The orthometric height was determined by GPS observations and a
AI4198.high-resolution geoid model using precise GPS observation and
AI4198.processing techniques.
AI4198
AI4198.Significant digits in the geoid height do not necessarily reflect accuracy.
AI4198.GEOID18 height accuracy estimate available here.
AI4198
AI4198.The PID for the CORS L1 Phase Center is DS2695.

AI4198.Click photographs - Photos may exist for this station.
AI4198
AI4198.The XYZ, and position/ellipsoidal ht. are equivalent.
AI4198
AI4198.The ellipsoidal height was determined by GPS observations
AI4198.and is referenced to NAD 83.
