DJ8961.The coordinates were established by GPS observations
DJ8961.and adjusted by the National Geodetic Survey in April 2022.
DJ8961
DJ8961.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DJ8961.been affixed to the stable North American Tectonic Plate.
DJ8961
DJ8961.The coordinates are valid at the epoch date displayed above
DJ8961.which is a decimal equivalence of Year/Month/Day.
DJ8961
DJ8961.Due to the release of the International GNSS Service (IGS) 2014
DJ8961.realization of the International Terrestrial Reference Frame of 2014
DJ8961.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DJ8961.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DJ8961.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DJ8961.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DJ8961.currently published epoch of 2010.00.
DJ8961
DJ8961.Additional information on MYCS2 is available at
DJ8961.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DJ8961
DJ8961.The orthometric height was determined by GPS observations and a
DJ8961.high-resolution geoid model using precise GPS observation and
DJ8961.processing techniques.
DJ8961
DJ8961.Significant digits in the geoid height do not necessarily reflect accuracy.
DJ8961.GEOID18 height accuracy estimate available here.
DJ8961
DJ8961.The PID for the CORS L1 Phase Center is DR7733.

DJ8961
DJ8961.The XYZ, and position/ellipsoidal ht. are equivalent.
DJ8961
DJ8961.The ellipsoidal height was determined by GPS observations
DJ8961.and is referenced to NAD 83.
