AI8823.The coordinates were established by GPS observations
AI8823.and adjusted by the National Geodetic Survey in June 2019.
AI8823
AI8823.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI8823.been affixed to the stable North American Tectonic Plate.
AI8823
AI8823.The coordinates are valid at the epoch date displayed above
AI8823.which is a decimal equivalence of Year/Month/Day.
AI8823
AI8823.Due to the release of the International GNSS Service (IGS) 2014
AI8823.realization of the International Terrestrial Reference Frame of 2014
AI8823.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI8823.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI8823.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI8823.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI8823.currently published epoch of 2010.00.
AI8823
AI8823.Additional information on MYCS2 is available at
AI8823.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI8823
AI8823.The orthometric height was determined by differential leveling.
AI8823.The vertical network tie was performed by a horz. field party for horz.
AI8823.obs reductions. Reset procedures were used to establish the elevation.
AI8823
AI8823.Significant digits in the geoid height do not necessarily reflect accuracy.
AI8823.GEOID18 height accuracy estimate available here.

AI8823.The PID for the CORS L1 Phase Center is AI8824.

AI8823.Click photographs - Photos may exist for this station.
AI8823
AI8823.The XYZ, and position/ellipsoidal ht. are equivalent.
AI8823
AI8823.The ellipsoidal height was determined by GPS observations
AI8823.and is referenced to NAD 83.
