DM2676.The coordinates were established by GPS observations
DM2676.and adjusted by the National Geodetic Survey in December 2022.
DM2676
DM2676.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2676.been affixed to the stable North American Tectonic Plate.
DM2676
DM2676.The coordinates are valid at the epoch date displayed above
DM2676.which is a decimal equivalence of Year/Month/Day.
DM2676
DM2676.Due to the release of the International GNSS Service (IGS) 2014
DM2676.realization of the International Terrestrial Reference Frame of 2014
DM2676.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2676.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2676.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2676.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2676.currently published epoch of 2010.00.
DM2676
DM2676.Additional information on MYCS2 is available at
DM2676.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM2676
DM2676.The orthometric height was determined by differential leveling and
DM2676.adjusted by the NATIONAL GEODETIC SURVEY
DM2676.in August 2012.
DM2676
DM2676.No vertical observational check was made to the station.
DM2676
DM2676.Significant digits in the geoid height do not necessarily reflect accuracy.
DM2676.GEOID18 height accuracy estimate available here.
DM2676
DM2676.The PID for the CORS L1 Phase Center is DR8322.

DM2676.Click photographs - Photos may exist for this station.
DM2676
DM2676.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2676
DM2676.The ellipsoidal height was determined by GPS observations
DM2676.and is referenced to NAD 83.
