DL9818.The coordinates were established by GPS observations
DL9818.and adjusted by the National Geodetic Survey in June 2019.
DL9818
DL9818.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL9818.been affixed to the stable North American Tectonic Plate.
DL9818
DL9818.The coordinates are valid at the epoch date displayed above
DL9818.which is a decimal equivalence of Year/Month/Day.
DL9818
DL9818.Due to the release of the International GNSS Service (IGS) 2014
DL9818.realization of the International Terrestrial Reference Frame of 2014
DL9818.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL9818.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL9818.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL9818.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL9818.currently published epoch of 2010.00.
DL9818
DL9818.Additional information on MYCS2 is available at
DL9818.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL9818
DL9818.The orthometric height was determined by GPS observations and a
DL9818.high-resolution geoid model using precise GPS observation and
DL9818.processing techniques.
DL9818
DL9818.Significant digits in the geoid height do not necessarily reflect accuracy.
DL9818.GEOID18 height accuracy estimate available here.
DL9818
DL9818.The PID for the CORS L1 Phase Center is DL9819.

DL9818.Click photographs - Photos may exist for this station.
DL9818
DL9818.The XYZ, and position/ellipsoidal ht. are equivalent.
DL9818
DL9818.The ellipsoidal height was determined by GPS observations
DL9818.and is referenced to NAD 83.
