DL3184.The coordinates were established by GPS observations
DL3184.and adjusted by the National Geodetic Survey in June 2019.
DL3184
DL3184.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3184.been affixed to the stable North American Tectonic Plate.
DL3184
DL3184.The coordinates are valid at the epoch date displayed above
DL3184.which is a decimal equivalence of Year/Month/Day.
DL3184
DL3184.Due to the release of the International GNSS Service (IGS) 2014
DL3184.realization of the International Terrestrial Reference Frame of 2014
DL3184.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3184.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3184.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3184.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3184.currently published epoch of 2010.00.
DL3184
DL3184.Additional information on MYCS2 is available at
DL3184.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL3184
DL3184.The orthometric height was determined by GPS observations and a
DL3184.high-resolution geoid model using precise GPS observation and
DL3184.processing techniques.
DL3184
DL3184.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3184.GEOID18 height accuracy estimate available here.
DL3184
DL3184.The PID for the CORS L1 Phase Center is DQ6488.

DL3184.Click photographs - Photos may exist for this station.
DL3184
DL3184.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3184
DL3184.The ellipsoidal height was determined by GPS observations
DL3184.and is referenced to NAD 83.
