DL1888.The coordinates were established by GPS observations
DL1888.and adjusted by the National Geodetic Survey in January 2023.
DL1888
DL1888.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL1888.been affixed to the stable North American Tectonic Plate.
DL1888
DL1888.The coordinates are valid at the epoch date displayed above
DL1888.which is a decimal equivalence of Year/Month/Day.
DL1888
DL1888.Due to the release of the International GNSS Service (IGS) 2014
DL1888.realization of the International Terrestrial Reference Frame of 2014
DL1888.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL1888.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL1888.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL1888.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL1888.currently published epoch of 2010.00.
DL1888
DL1888.Additional information on MYCS2 is available at
DL1888.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL1888.Significant digits in the geoid height do not necessarily reflect accuracy.

DL1888.The XYZ, and position/ellipsoidal ht. are equivalent.
DL1888
DL1888.The ellipsoidal height was determined by GPS observations
DL1888.and is referenced to NAD 83.
