DL7622.The coordinates were established by GPS observations
DL7622.and adjusted by the National Geodetic Survey in May 2022.
DL7622
DL7622.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7622.been affixed to the stable North American Tectonic Plate.
DL7622
DL7622.The coordinates are valid at the epoch date displayed above
DL7622.which is a decimal equivalence of Year/Month/Day.
DL7622
DL7622.Due to the release of the International GNSS Service (IGS) 2014
DL7622.realization of the International Terrestrial Reference Frame of 2014
DL7622.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7622.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7622.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7622.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7622.currently published epoch of 2010.00.
DL7622
DL7622.Additional information on MYCS2 is available at

DL7622.** This station is in an area of known vertical motion. Due to the
DL7622.** variability of land subsidence, uplift, and crustal motion, NGS has,
DL7622.** determined the orthometric heights for marks in these suspect
DL7622.** subsidence areas should be considered valid only at the epoch date
DL7622.** associated with the orthometric height. These heights must always
DL7622.** be validated when used as control. All previously superseded
DL7622.** orthometric heights are now considered suspect and are available
DL7622.** in the superseded section. NGS does not recommend using suspect
DL7622.** or superseded heights as control.
DL7622
DL7622.The orthometric height was determined by GPS observations and a
DL7622.high-resolution geoid model using precise GPS observation and
DL7622.processing techniques.
DL7622
DL7622.Significant digits in the geoid height do not necessarily reflect accuracy.
DL7622.GEOID18 height accuracy estimate available here.
DL7622
DL7622.The PID for the CORS L1 Phase Center is DR1518.

DL7622
DL7622.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7622
DL7622.The ellipsoidal height was determined by GPS observations
DL7622.and is referenced to NAD 83.
