DH7107.The coordinates were established by GPS observations
DH7107.and adjusted by the National Geodetic Survey in July 2022.
DH7107
DH7107.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7107.been affixed to the stable North American Tectonic Plate.
DH7107
DH7107.The coordinates are valid at the epoch date displayed above
DH7107.which is a decimal equivalence of Year/Month/Day.
DH7107
DH7107.Due to the release of the International GNSS Service (IGS) 2014
DH7107.realization of the International Terrestrial Reference Frame of 2014
DH7107.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7107.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7107.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7107.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7107.currently published epoch of 2010.00.
DH7107
DH7107.Additional information on MYCS2 is available at
DH7107.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH7107
DH7107.The orthometric height was determined by differential leveling and
DH7107.adjusted by the NATIONAL GEODETIC SURVEY
DH7107.in April 2014.
DH7107
DH7107.No vertical observational check was made to the station.
DH7107
DH7107.Significant digits in the geoid height do not necessarily reflect accuracy.
DH7107.GEOID18 height accuracy estimate available here.
DH7107
DH7107.The PID for the CORS L1 Phase Center is DQ6778.

DH7107.Click photographs - Photos may exist for this station.
DH7107
DH7107.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7107
DH7107.The ellipsoidal height was determined by GPS observations
DH7107.and is referenced to NAD 83.
