DL3494.The coordinates were established by GPS observations
DL3494.and adjusted by the National Geodetic Survey in June 2019.
DL3494
DL3494.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3494.been affixed to the stable North American Tectonic Plate.
DL3494
DL3494.The coordinates are valid at the epoch date displayed above
DL3494.which is a decimal equivalence of Year/Month/Day.
DL3494
DL3494.Due to the release of the International GNSS Service (IGS) 2014
DL3494.realization of the International Terrestrial Reference Frame of 2014
DL3494.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3494.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3494.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3494.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3494.currently published epoch of 2010.00.
DL3494
DL3494.Additional information on MYCS2 is available at
DL3494.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL3494
DL3494.The orthometric height was determined by GPS observations and a
DL3494.high-resolution geoid model using precise GPS observation and
DL3494.processing techniques.
DL3494
DL3494.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3494.GEOID18 height accuracy estimate available here.
DL3494
DL3494.The PID for the CORS L1 Phase Center is DR7753.

DL3494.Click photographs - Photos may exist for this station.
DL3494
DL3494.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3494
DL3494.The ellipsoidal height was determined by GPS observations
DL3494.and is referenced to NAD 83.
