DL6500.The coordinates were established by GPS observations
DL6500.and adjusted by the National Geodetic Survey in August 2024.
DL6500
DL6500.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6500.been affixed to the stable North American Tectonic Plate.
DL6500
DL6500.The coordinates are valid at the epoch date displayed above
DL6500.which is a decimal equivalence of Year/Month/Day.
DL6500
DL6500.Due to the release of the International GNSS Service (IGS) 2014
DL6500.realization of the International Terrestrial Reference Frame of 2014
DL6500.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6500.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6500.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6500.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6500.currently published epoch of 2010.00.
DL6500
DL6500.Additional information on MYCS2 is available at
DL6500.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6500.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6500
DL6500.The ellipsoidal height was determined by GPS observations
DL6500.and is referenced to NAD 83.
