DL1707.The coordinates were established by GPS observations
DL1707.and adjusted by the National Geodetic Survey in May 2021.
DL1707
DL1707.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL1707.been affixed to the stable North American Tectonic Plate.
DL1707
DL1707.The coordinates are valid at the epoch date displayed above
DL1707.which is a decimal equivalence of Year/Month/Day.
DL1707
DL1707.Due to the release of the International GNSS Service (IGS) 2014
DL1707.realization of the International Terrestrial Reference Frame of 2014
DL1707.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL1707.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL1707.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL1707.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL1707.currently published epoch of 2010.00.
DL1707
DL1707.Additional information on MYCS2 is available at
DL1707.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL1707
DL1707.The orthometric height was determined by GPS observations and a
DL1707.high-resolution geoid model using precise GPS observation and
DL1707.processing techniques.
DL1707
DL1707.Significant digits in the geoid height do not necessarily reflect accuracy.
DL1707.GEOID18 height accuracy estimate available here.
DL1707
DL1707.The PID for the CORS L1 Phase Center is DR7749.

DL1707
DL1707.The XYZ, and position/ellipsoidal ht. are equivalent.
DL1707
DL1707.The ellipsoidal height was determined by GPS observations
DL1707.and is referenced to NAD 83.
