DL1900.The coordinates were established by GPS observations
DL1900.and adjusted by the National Geodetic Survey in May 2020.
DL1900
DL1900.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL1900.been affixed to the stable North American Tectonic Plate.
DL1900
DL1900.The coordinates are valid at the epoch date displayed above
DL1900.which is a decimal equivalence of Year/Month/Day.
DL1900
DL1900.Due to the release of the International GNSS Service (IGS) 2014
DL1900.realization of the International Terrestrial Reference Frame of 2014
DL1900.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL1900.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL1900.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL1900.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL1900.currently published epoch of 2010.00.
DL1900
DL1900.Additional information on MYCS2 is available at
DL1900.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL1900
DL1900.The orthometric height was determined by GPS observations and a
DL1900.high-resolution geoid model using precise GPS observation and
DL1900.processing techniques.
DL1900
DL1900.Significant digits in the geoid height do not necessarily reflect accuracy.
DL1900.GEOID18 height accuracy estimate available here.
DL1900
DL1900.The PID for the CORS L1 Phase Center is DR3612.

DL1900.Click photographs - Photos may exist for this station.
DL1900
DL1900.The XYZ, and position/ellipsoidal ht. are equivalent.
DL1900
DL1900.The ellipsoidal height was determined by GPS observations
DL1900.and is referenced to NAD 83.
