AM7024.The coordinates were established by GPS observations
AM7024.and adjusted by the National Geodetic Survey in June 2019.
AM7024
AM7024.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AM7024.been affixed to the stable North American Tectonic Plate.
AM7024
AM7024.The coordinates are valid at the epoch date displayed above
AM7024.which is a decimal equivalence of Year/Month/Day.
AM7024
AM7024.Due to the release of the International GNSS Service (IGS) 2014
AM7024.realization of the International Terrestrial Reference Frame of 2014
AM7024.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AM7024.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AM7024.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AM7024.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AM7024.currently published epoch of 2010.00.
AM7024
AM7024.Additional information on MYCS2 is available at
AM7024.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AM7024
AM7024.The orthometric height was determined by GPS observations and a
AM7024.high-resolution geoid model using precise GPS observation and
AM7024.processing techniques.
AM7024
AM7024.Significant digits in the geoid height do not necessarily reflect accuracy.
AM7024.GEOID18 height accuracy estimate available here.
AM7024
AM7024.The PID for the CORS L1 Phase Center is DR1462.

AM7024.Click photographs - Photos may exist for this station.
AM7024
AM7024.The XYZ, and position/ellipsoidal ht. are equivalent.
AM7024
AM7024.The ellipsoidal height was determined by GPS observations
AM7024.and is referenced to NAD 83.
