DM3483.The coordinates were established by GPS observations
DM3483.and adjusted by the National Geodetic Survey in July 2022.
DM3483
DM3483.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3483.been affixed to the stable North American Tectonic Plate.
DM3483
DM3483.The coordinates are valid at the epoch date displayed above
DM3483.which is a decimal equivalence of Year/Month/Day.
DM3483
DM3483.Due to the release of the International GNSS Service (IGS) 2014
DM3483.realization of the International Terrestrial Reference Frame of 2014
DM3483.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3483.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3483.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3483.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3483.currently published epoch of 2010.00.
DM3483
DM3483.Additional information on MYCS2 is available at
DM3483.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM3483
DM3483.The orthometric height was determined by differential leveling and
DM3483.adjusted by the NATIONAL GEODETIC SURVEY
DM3483.in August 2012.
DM3483
DM3483.No vertical observational check was made to the station.
DM3483
DM3483.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3483.GEOID18 height accuracy estimate available here.
DM3483
DM3483.The PID for the CORS L1 Phase Center is DR4865.

DM3483.Click photographs - Photos may exist for this station.
DM3483
DM3483.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3483
DM3483.The ellipsoidal height was determined by GPS observations
DM3483.and is referenced to NAD 83.
