DL6898.The coordinates were established by GPS observations
DL6898.and adjusted by the National Geodetic Survey in June 2019.
DL6898
DL6898.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6898.been affixed to the stable North American Tectonic Plate.
DL6898
DL6898.The coordinates are valid at the epoch date displayed above
DL6898.which is a decimal equivalence of Year/Month/Day.
DL6898
DL6898.Due to the release of the International GNSS Service (IGS) 2014
DL6898.realization of the International Terrestrial Reference Frame of 2014
DL6898.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6898.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6898.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6898.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6898.currently published epoch of 2010.00.
DL6898
DL6898.Additional information on MYCS2 is available at
DL6898.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL6898
DL6898.The orthometric height was determined by GPS observations and a
DL6898.high-resolution geoid model using precise GPS observation and
DL6898.processing techniques.
DL6898
DL6898.Significant digits in the geoid height do not necessarily reflect accuracy.
DL6898.GEOID18 height accuracy estimate available here.
DL6898
DL6898.The PID for the CORS L1 Phase Center is DR4863.

DL6898.Click photographs - Photos may exist for this station.
DL6898
DL6898.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6898
DL6898.The ellipsoidal height was determined by GPS observations
DL6898.and is referenced to NAD 83.
