DO1740.The coordinates were established by GPS observations
DO1740.and adjusted by the National Geodetic Survey in June 2019.
DO1740
DO1740.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO1740.been affixed to the stable North American Tectonic Plate.
DO1740
DO1740.The coordinates are valid at the epoch date displayed above
DO1740.which is a decimal equivalence of Year/Month/Day.
DO1740
DO1740.Due to the release of the International GNSS Service (IGS) 2014
DO1740.realization of the International Terrestrial Reference Frame of 2014
DO1740.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO1740.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO1740.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO1740.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO1740.currently published epoch of 2010.00.
DO1740
DO1740.Additional information on MYCS2 is available at
DO1740.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO1740.Significant digits in the geoid height do not necessarily reflect accuracy.
DO1740.GEOID18 height accuracy estimate available here.

DO1740.Click photographs - Photos may exist for this station.
DO1740
DO1740.The XYZ, and position/ellipsoidal ht. are equivalent.
DO1740
DO1740.The ellipsoidal height was determined by GPS observations
DO1740.and is referenced to NAD 83.
