DL2080.The coordinates were established by GPS observations
DL2080.and adjusted by the National Geodetic Survey in June 2019.
DL2080
DL2080.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2080.been affixed to the stable North American Tectonic Plate.
DL2080
DL2080.The coordinates are valid at the epoch date displayed above
DL2080.which is a decimal equivalence of Year/Month/Day.
DL2080
DL2080.Due to the release of the International GNSS Service (IGS) 2014
DL2080.realization of the International Terrestrial Reference Frame of 2014
DL2080.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2080.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2080.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2080.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2080.currently published epoch of 2010.00.
DL2080
DL2080.Additional information on MYCS2 is available at
DL2080.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL2080
DL2080.The orthometric height was determined by GPS observations and a
DL2080.high-resolution geoid model using precise GPS observation and
DL2080.processing techniques.
DL2080
DL2080.Significant digits in the geoid height do not necessarily reflect accuracy.
DL2080.GEOID18 height accuracy estimate available here.
DL2080
DL2080.The PID for the CORS L1 Phase Center is DS2807.

DL2080.Click photographs - Photos may exist for this station.
DL2080
DL2080.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2080
DL2080.The ellipsoidal height was determined by GPS observations
DL2080.and is referenced to NAD 83.
