DL2071.The coordinates were established by GPS observations
DL2071.and adjusted by the National Geodetic Survey in June 2019.
DL2071
DL2071.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2071.been affixed to the stable North American Tectonic Plate.
DL2071
DL2071.The coordinates are valid at the epoch date displayed above
DL2071.which is a decimal equivalence of Year/Month/Day.
DL2071
DL2071.Due to the release of the International GNSS Service (IGS) 2014
DL2071.realization of the International Terrestrial Reference Frame of 2014
DL2071.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2071.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2071.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2071.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2071.currently published epoch of 2010.00.
DL2071
DL2071.Additional information on MYCS2 is available at
DL2071.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL2071
DL2071.The orthometric height was determined by differential leveling and
DL2071.adjusted by the NATIONAL GEODETIC SURVEY
DL2071.in April 2009.
DL2071
DL2071.No vertical observational check was made to the station.
DL2071
DL2071.Significant digits in the geoid height do not necessarily reflect accuracy.
DL2071.GEOID18 height accuracy estimate available here.
DL2071
DL2071.The PID for the CORS L1 Phase Center is DR9320.

DL2071.Click photographs - Photos may exist for this station.
DL2071
DL2071.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2071
DL2071.The ellipsoidal height was determined by GPS observations
DL2071.and is referenced to NAD 83.
