DL2308.The coordinates were established by GPS observations
DL2308.and adjusted by the National Geodetic Survey in June 2019.
DL2308
DL2308.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2308.been affixed to the stable North American Tectonic Plate.
DL2308
DL2308.The coordinates are valid at the epoch date displayed above
DL2308.which is a decimal equivalence of Year/Month/Day.
DL2308
DL2308.Due to the release of the International GNSS Service (IGS) 2014
DL2308.realization of the International Terrestrial Reference Frame of 2014
DL2308.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2308.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2308.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2308.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2308.currently published epoch of 2010.00.
DL2308
DL2308.Additional information on MYCS2 is available at
DL2308.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL2308
DL2308.The orthometric height was determined by GPS observations and a
DL2308.high-resolution geoid model using precise GPS observation and
DL2308.processing techniques.
DL2308
DL2308.Significant digits in the geoid height do not necessarily reflect accuracy.
DL2308.GEOID18 height accuracy estimate available here.
DL2308
DL2308.The PID for the CORS L1 Phase Center is DP2659.

DL2308.Click photographs - Photos may exist for this station.
DL2308
DL2308.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2308
DL2308.The ellipsoidal height was determined by GPS observations
DL2308.and is referenced to NAD 83.
