DL3506.The coordinates were established by GPS observations
DL3506.and adjusted by the National Geodetic Survey in May 2021.
DL3506
DL3506.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3506.been affixed to the stable North American Tectonic Plate.
DL3506
DL3506.The coordinates are valid at the epoch date displayed above
DL3506.which is a decimal equivalence of Year/Month/Day.
DL3506
DL3506.Due to the release of the International GNSS Service (IGS) 2014
DL3506.realization of the International Terrestrial Reference Frame of 2014
DL3506.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3506.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3506.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3506.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3506.currently published epoch of 2010.00.
DL3506
DL3506.Additional information on MYCS2 is available at
DL3506.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3506.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3506.GEOID18 height accuracy estimate available here.

DL3506.Click photographs - Photos may exist for this station.
DL3506
DL3506.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3506
DL3506.The ellipsoidal height was determined by GPS observations
DL3506.and is referenced to NAD 83.
