DL1890.The coordinates were established by GPS observations
DL1890.and adjusted by the National Geodetic Survey in March 2023.
DL1890
DL1890.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL1890.been affixed to the stable North American Tectonic Plate.
DL1890
DL1890.The coordinates are valid at the epoch date displayed above
DL1890.which is a decimal equivalence of Year/Month/Day.
DL1890
DL1890.Due to the release of the International GNSS Service (IGS) 2014
DL1890.realization of the International Terrestrial Reference Frame of 2014
DL1890.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL1890.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL1890.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL1890.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL1890.currently published epoch of 2010.00.
DL1890
DL1890.Additional information on MYCS2 is available at
DL1890.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL1890
DL1890.The orthometric height was determined by GPS observations and a
DL1890.high-resolution geoid model using precise GPS observation and
DL1890.processing techniques.
DL1890
DL1890.Significant digits in the geoid height do not necessarily reflect accuracy.
DL1890.GEOID18 height accuracy estimate available here.
DL1890
DL1890.The PID for the CORS L1 Phase Center is DR1512.

DL1890
DL1890.The XYZ, and position/ellipsoidal ht. are equivalent.
DL1890
DL1890.The ellipsoidal height was determined by GPS observations
DL1890.and is referenced to NAD 83.
