DM2680.The coordinates were established by GPS observations
DM2680.and adjusted by the National Geodetic Survey in April 2022.
DM2680
DM2680.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2680.been affixed to the stable North American Tectonic Plate.
DM2680
DM2680.The coordinates are valid at the epoch date displayed above
DM2680.which is a decimal equivalence of Year/Month/Day.
DM2680
DM2680.Due to the release of the International GNSS Service (IGS) 2014
DM2680.realization of the International Terrestrial Reference Frame of 2014
DM2680.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2680.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2680.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2680.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2680.currently published epoch of 2010.00.
DM2680
DM2680.Additional information on MYCS2 is available at
DM2680.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM2680
DM2680.The orthometric height was determined by differential leveling and
DM2680.adjusted by the NATIONAL GEODETIC SURVEY
DM2680.in August 2012.
DM2680
DM2680.No vertical observational check was made to the station.
DM2680
DM2680.Significant digits in the geoid height do not necessarily reflect accuracy.
DM2680.GEOID18 height accuracy estimate available here.
DM2680
DM2680.The PID for the CORS L1 Phase Center is DM2681.

DM2680.Click photographs - Photos may exist for this station.
DM2680
DM2680.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2680
DM2680.The ellipsoidal height was determined by GPS observations
DM2680.and is referenced to NAD 83.
