DM2678.The coordinates were established by GPS observations
DM2678.and adjusted by the National Geodetic Survey in June 2019.
DM2678
DM2678.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2678.been affixed to the stable North American Tectonic Plate.
DM2678
DM2678.The coordinates are valid at the epoch date displayed above
DM2678.which is a decimal equivalence of Year/Month/Day.
DM2678
DM2678.Due to the release of the International GNSS Service (IGS) 2014
DM2678.realization of the International Terrestrial Reference Frame of 2014
DM2678.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2678.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2678.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2678.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2678.currently published epoch of 2010.00.
DM2678
DM2678.Additional information on MYCS2 is available at
DM2678.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM2678
DM2678.The orthometric height was determined by differential leveling and
DM2678.adjusted by the NATIONAL GEODETIC SURVEY
DM2678.in August 2012.
DM2678
DM2678.No vertical observational check was made to the station.
DM2678
DM2678.Significant digits in the geoid height do not necessarily reflect accuracy.
DM2678.GEOID18 height accuracy estimate available here.
DM2678
DM2678.The PID for the CORS L1 Phase Center is DM2679.

DM2678.Click photographs - Photos may exist for this station.
DM2678
DM2678.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2678
DM2678.The ellipsoidal height was determined by GPS observations
DM2678.and is referenced to NAD 83.
