DM2662.The coordinates were established by GPS observations
DM2662.and adjusted by the National Geodetic Survey in April 2022.
DM2662
DM2662.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2662.been affixed to the stable North American Tectonic Plate.
DM2662
DM2662.The coordinates are valid at the epoch date displayed above
DM2662.which is a decimal equivalence of Year/Month/Day.
DM2662
DM2662.Due to the release of the International GNSS Service (IGS) 2014
DM2662.realization of the International Terrestrial Reference Frame of 2014
DM2662.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2662.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2662.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2662.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2662.currently published epoch of 2010.00.
DM2662
DM2662.Additional information on MYCS2 is available at
DM2662.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM2662
DM2662.The orthometric height was determined by differential leveling and
DM2662.adjusted by the NATIONAL GEODETIC SURVEY
DM2662.in December 2011.
DM2662
DM2662.No vertical observational check was made to the station.
DM2662
DM2662.Significant digits in the geoid height do not necessarily reflect accuracy.
DM2662.GEOID18 height accuracy estimate available here.
DM2662
DM2662.The PID for the CORS L1 Phase Center is DR8321.

DM2662.Click photographs - Photos may exist for this station.
DM2662
DM2662.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2662
DM2662.The ellipsoidal height was determined by GPS observations
DM2662.and is referenced to NAD 83.
